The prevailing winds of the atmospheric circulation arise because of the difference in pressure at various latitudes and act as means for distribution of thermal energy on the planet. The intense heat over the Tibetan Plateau, coupled with associated terrain features like the high altitude of the plateau, generate the tropical easterly jet over central India. [Note 7]. The unique geographical features of the Indian subcontinent, along with associated atmospheric, oceanic, and geophysical factors, influence the behavior of the monsoon. Kerala's State Disaster Management Authority, "Dozens feared dead in India landslide after floods", "Toll in Idukki Landslide Rises to 52 as Three More Bodies Recovered", "Kerala rains: 22 dead in Idukki landslide, search resumes for 43 missing", "Air India jet breaks in two in Kerala, killing 18", Tea plantation landslide kills 49 in India as more feared buried, "A Step at a Time: How Kerala Can Start Picking up the Pieces", "Dip in rainfall,but State to remain on alert", https://en.wikipedia.org/w/index.php?title=2020_Kerala_floods&oldid=987311458, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 November 2020, at 06:12. According to this theory, the monsoon is a result of the shift of the Inter Tropical Convergence Zone (ITCZ) under the influence of the vertical sun. Although the ENSO effect was statistically effective in explaining several past droughts in India, in recent decades, its relationship with the Indian monsoon seemed to weaken. On 7 August 2020, due to heavy rainfall in the monsoon season, severe floods affected Kerala , India. , The rainfall is a result of the convergence of wind flow from the Bay of Bengal and reverse winds from the South China Sea. As a security measure in the prevailing situation of heavy rains, the India Meteorological Department had issued Red alert in the 9 districts in Northern and Central Kerala, orange alert in 3 districts of Central Kerala, and yellow alert in the 2 districts of southern Kerala. 2018 Kerala floods Date July 2018 (2018-07) â August 2018 Location Kerala, India Cause Low pressure Heavy rain Discharges Landslide Deaths 483 dead,140 went missing Property damage â¹ 400 billion (US$5.6 billion) (estimated) On 16 August 2018, severe floods affected the south Indian state Kerala, due to unusually high rainfall during the monsoon season. The reverse condition is known as La Niña. People love the Kerala experience during the monsoon. This causes the winds to blow over the Indian subcontinent toward the Indian Ocean in a northeasterly direction, causing the northeast monsoon. Monsoon In Kerala, IndiaKerala receives most of its rainfall in two distinguished monsoon seasons. 1.  A Southern Oscillation Index (SOI), based on the pressure difference between Tahiti and Darwin, has been formulated by the Bureau of Meteorology (Australia) to measure the strength of the oscillation. Alternating belts of high pressure and low pressure develop along the equator, the two tropics, the Arctic and Antarctic circles, and the two polar regions, giving rise to the trade winds, the westerlies, and the polar easterlies. See photos taken only three months apart in the Western Ghats. Only part of the northeast monsoon passing over the Bay of Bengal picks up moisture, causing rain in Andhra Pradesh and Tamil Nadu during the winter months. A normal monsoon is generally accepted to be one involving close to the average quantity of precipitation over all the geographical locations under its influence (mean spatial distribution) and over the entire expected time period (mean temporal distribution). Because of the lofty Himalayas, the westerly jet's movement is inhibited. According to this theory, the onset of the southwest monsoon is driven by the shift of the subtropical westerly jet north from over the plains of India toward the Tibetan Plateau. Kerala's State Disaster Management Authority, Kerala police along with the Indian Air Force, civilians, volunteers, fishermen from coastal Kerala are actively taking part in the rescue operations in flood-affected regions. Mawsynram and Cherrapunji, both in the Indian state of Meghalaya, alternate as the wettest places on Earth given the quantity of their rainfall, though there are other cities with similar claims. The word monsoon (derived from the Arabic "mausim", meaning "seasonal reversal of winds"), although generally defined as a system of winds characterized by a seasonal reversal of direction, lacks a consistent, detailed definition.  As the Tibetan Plateau heats up, the low pressure created over it pulls the westerly jet north. As such, during the northern summer (May and June), the ITCZ moves north, along with the vertical sun, toward the Tropic of Cancer.  After arriving slightly before time, Southwest Monsoon has now covered the entire state of Kerala. It states that during the hot subtropical summers, the massive landmass of the Indian Peninsula heats up at a different rate than the surrounding seas, resulting in a pressure gradient from south to north.  On 9 August 2020, 49 people died during a landslide at a tea plantation in Rajamala.  Walker noticed that when pressure was high in Tahiti, it was low in Darwin, and vice versa. , The Centre for Development of Advanced Computing (CDAC) at Bengaluru facilitated the Seasonal Prediction of Indian Monsoon (SPIM) experiment on the PARAM Padma supercomputing system. They receive more than 11,000 millimeters of rain each from the monsoon. Despite progress in alternative forms of irrigation, agricultural dependence on the monsoon remains far from insignificant. As one of the tropical destination, Kerala is now at heavenly climate throughout this monsoon season. Additionally, the arrival date and the departure date of both the southwest and northeast monsoon should be close to the mean dates. Geographical features of the Indian subcontinent. Updated: 10 Jun 2019, 08:06 AM IST Nidheesh M.K. , The monsoon is the primary bearer of fresh water to the area.  In negative dipole years, the reverse happens, making Indonesia much warmer and rainier. One major drawback of traveling during the monsoon is that most wildlife sanctuaries are closed. Though the normal rainfall for Kerala for the entire month of August is only 427mm, the state received 476mm in the first ten days of August itself.. The mechanism affecting the monsoon is that the westerly jet causes high pressure over northern parts of the subcontinent during the winter. El Niño is a warm ocean current originating along the coast of Peru that replaces the usual cold Humboldt Current. The reverse shift takes place for the northeast monsoon winds, leading to a second, minor burst of rainfall over the eastern Indian Peninsula during the Northern Hemisphere winter months. On 8 August 2019, due to heavy rainfall in the Monsoon season, severe flood affected Kerala. Two factors are essential for rain formation: Additionally, one of the causes of rain must happen. 483 osoby zginÄÅy, a co najmniej 82 400 zostaÅo uratowanych.. Powodzie. These include diseases such as dengue, malaria, cholera, and colds. This criticism does not deny the role of differential heating of sea and land in generating monsoon winds, but casts it as one of several factors rather than the only one. School Certificates Ruined In Flood, Kerala â¦ It is only when the Tibetan Plateau heats up significantly more than the Himalayas that the ITCZ rises abruptly and swiftly shifts north, leading to the bursting of monsoon rains over the Indian subcontinent.  On the same day, the Air India Express Flight 1344 carrying 191 people crashed in Kerala, resulting in the death of 18 people and the wounding of several others. They follow the principle of geostrophic winds. Between the two monsoon seasons, the temperature remains cool in most parts of Kerala. The relevant features in explaining the monsoon mechanism are as follows: Pink arrow: Southwest monsoon wind direction; green arrow: northeast monsoon wind direction. Although the southwest and northeast monsoon winds are seasonally reversible, they do cause precipitation on their own. Consequently, the air above coastal lands heats up faster than the air above seas. Striking a perfect balance between the hilly areas and the coastal region, monsoon in Kerala are majorly of two types. Kerala was also flooded in 2018 and 2019. , Seasonal Prediction of Indian Monsoon (SPIM), The name of the wind is based on the direction that it blows, First, the Himalayas serve as orographic barriers to the southwest monsoon winds. Find the perfect kerala monsoon stock photo. Monsoon season in Kerala is a unique experience. , The onset of the monsoon occurs over the Bay of Bengal in May, arriving at the Indian Peninsula by June, and then the winds move towards the South China Sea.. New Delhi: Kerala, one of the southernmost states of India that shares its coastline with the Arabian Sea, has experienced numerous floods in the past.Monsoon has wreaked havoc in âGodâs Own Countryâ for decades and what we see today is just another paradigm of natureâs fury. The reduction in the summer monsoon rainfall have grave consequences over central India because at least 60% of the agriculture in this region is still largely rain-fed.  His own career prospects, his emotional well-being, and the performance of his monetary policy are all "a hostage" to the monsoon, he said, as is the case for most Indians.  On reaching land, these winds rise because of the geographical relief, cooling adiabatically and leading to orographic rains. Several theories have been proposed to explain the origin, process, strength, variability, distribution, and general vagaries of the monsoon, but understanding and predictability are still evolving.  The observed monsoon rainfall indicates a gradual decline over central India, with a reduction of up to 10%.  Heavy rains in Idukki have caused severe landslide in Munnar in which at least 52 people died and nearly 19 were reported missing.

There have been books written and films made which showcase the beauty of the state during the season. Westerly winds were exceptionally strong at the 850 hPa level, which helped the monsoon currents to penetrate into the ghats. The average temperature remains between 20°C and 35°C and the rainfall ranges between 2250 and 2500 mm. With the northward shift of the vertical sun, this jet shifts north, too. Canopy of Monsoon clouds..jpg 2,592 × 1,944; 325 KB Centre for monsoon studies - cochin university.JPG 4,752 × 3,168; 4.86 MB Chalakudy River anticipating the monsoons.jpg 5,184 × â¦ And Northeast monsoon, also known as the retreating monsoon, comes around October-November. [Note 5] However, because of the Coriolis effect (which causes winds in the Northern Hemisphere to turn right, whereas winds in the Southern Hemisphere turn left), these southeast trade winds are deflected east in the Northern Hemisphere, transforming into southwest trades. Therefore, the agricultural calendar of India is governed by the monsoon. , D. Subbarao, former governor of the Reserve Bank of India, emphasized during a quarterly review of India's monetary policy that the lives of Indians depend on the performance of the monsoon. Kerala's average maximum daily temperature is around 37 °C; the minimum is 19.8 °C. South West Monsoon. The dry, northeasterly trade winds, and their more extreme form, the harmattan, are interrupted by the northern sâ¦ The dynamic theory explains the monsoon on the basis of the annual shifts in the position of global belts of pressure and winds. This results in the southwest monsoon. Fourth, they are a major factor in the. In the case of the monsoon, the cause is primarily orographic, due to the presence of highlands in the path of the winds. Despite decreased rains, light to moderate rain with one or two heavy spells will continue during the next few days over Coastal Karnataka and Kerala. The monsoon of western Sub-Saharan Africa is the result of the seasonal shifts of the Intertropical Convergence Zone and the great seasonal temperature and humidity differences between the Sahara and the equatorial Atlantic Ocean. According to this theory, during the summer months in the Northern Hemisphere, the ITCZ shifts north, pulling the southwest monsoon winds onto the land from the sea. , The onset of the monsoon increases fungal and bacterial activity. 7. Heavy rains in Idukki have caused severe landslide in Munnar in which at least 52 people died and nearly 19 were reported missing. As a result, Kerala averages some 120â140 rainy days per year. The "bursting" of the monsoon is primarily explained by the jet stream theory and the dynamic theory. Since 1950s, the South Asian summer monsoon has been exhibiting large changes, especially in terms of droughts and floods. , Normally, the southwest monsoon can be expected to "burst" onto the western coast of India (near Thiruvananthapuram) at the beginning of June and to cover the entire country by mid-July. This season ( Edavappathi - as the rains starts by the middle of the Malayalam month Edavam ) begins by the end of May or early June with the outset of the southwest monsoon winds. First observed by World War II pilots, they develop just below the tropopause over areas of steep pressure gradient on the surface. Take a journey to this historic destination with your loved ones , famously known for the song from Bombay movie. No need to register, buy now! Bursting of monsoon refers to the sudden change in weather conditions in India (typically from hot and dry weather to wet and humid weather during the southwest monsoon), characterized by an abrupt rise in the mean daily rainfall. , The unnatural increase in rainfall was caused by a monsoon surge, which was aided by a strong Somali Current or Somali Jet and a low-pressure on the Bay of Bengal which dragged strong monsoon winds towards the Western Coast of India. The Northern Limit of Monsoon (NLM) is currently passing through Shirali, Hassan, Mysuru, Kodaikanal, and Tuticorin.Moreover, conditions are now conducive for the further advancement of Southwest Monsoon into some more parts of South India and may even touch parts of Northeast â¦  In India monsoons create an entire season in which the winds reverse completely.  As a result, the Indian government is actively working with farmers and the nation's meteorological department to produce more drought resistant crops.  As a security measure during the prevailing situation of heavy rains, the India Meteorological Department issued a red alert for the 3 districts of Wayanad, Kozhikkode and Idukki. However, many meteorologists argue that the monsoon is not a local phenomenon as explained by the traditional theory, but a general weather phenomenon along the entire tropical zone of Earth. Monsoon clouds - panoramio.jpg 1,600 × 1,200; 349 KB Monsoon Clouds Over Kochi.jpg 1,029 × 683; 130 KB Rainbow - Kochi from top of a building 01.jpg 3,264 × 1,840; 2.25 MB The Western Ghats are the first highlands of India that the southwest monsoon winds encounter. 545 Relief Camps were opened by the Government of Kerala and 12121 inmates were admitted into these relief camps. Southern oscillation, a phenomenon first observed by Sir Gilbert Thomas Walker, director general of observatories in India, refers to the seesaw relationship of atmospheric pressures between Tahiti and Darwin, Australia. Alappuzha This jet creates a low-pressure zone over the northern Indian plains, influencing the wind flow toward these plains and assisting the development of the southwest monsoon[clarification needed]. The Southwest Monsoon that arrives in the month of June is called Edavappathy, as it comes in the middle of the month of Edavam on the Malayalam Calendar. In summer, most of Kerala is prone to gale-force winds, storm surges, and torrential downpours accompanying dangerous cyclones coming in off the Indian Ocean. Precipitation then occurs on the windward side of the highlands because of adiabatic cooling and condensation of the moist rising air. Southwest monsoon, from June to August, is the main rainy season. It is a tropical land with, generally, pleasant climate. An orange alert was also issued for five districts. Monsoon rains are likely to hit the southern Kerala coast in two days, a top weather official said on Monday, easing concerns about the onset delay threatening plantings of â¦ Thus, the monsoon is one of the best periods for an escape to Kerala. The ITCZ migrates northward from the equatorial Atlantic in February, reaches western Africa on or near June 22, then moves back to the south by October. , The down side however is that when monsoon rains are weak, crop production is low leading to higher food prices with limited supply. The Monsoon season in Kerala is indeed a heavenly spectacle as the whole of earth rejoices after being revived from the harsh summer spell.  However, following the 2009 drought in India (worst since 1972), The department decided in 2010 that it needed to develop an "indigenous model" to further improve its prediction capabilities. Because the southwest monsoon flows from sea to land, it carries more moisture, and therefore causes more rain, than the northeast monsoon.  The state is reeling under damage to property worth Rs 19,000 crore, death of people, livestock and heavy loss to agriculture, especially in Kuttanad, Alappuzha, also known as ‘Kerala’s Rice Bowl’ and the state has submitted a comprehensive plan to Central government to improve the disaster management capacity of the state. Though the mean position of the ITCZ is taken as the equator, it shifts north and south with the migration of the vertical sun toward the Tropics of Cancer and Capricorn during the summer of the respective hemispheres (Northern and Southern Hemisphere). , One of the most commonly used words to describe the erratic nature of the monsoon is "vagaries", used in newspapers, magazines, books, web portals to insurance plans, and India's budget discussions.  Future changes in the monsoon will depend on a competition between land and ocean—on which is warming faster than the other. Orographic barriers force wind to rise. The effect is known to have a pronounced influence on the strength of the southwest monsoon over India, with the monsoon being weak (causing droughts) during El Niño years, while La Niña years bring particularly strong monsoons.. Powodzie w Kerali â klÄska Å¼ywioÅowa powodzi, która nawiedziÅa KeralÄ, stan w poÅudniowo-zachodnich Indiach, w sierpniu 2018 roku. All of these factors have positive ripple effects throughout the economy of India. On 7 August 2020, due to heavy rainfall in the monsoon season, severe floods affected Kerala, India. Monsoon in Kerala.  The relationship between extremes of the Indian summer monsoon rainfall, along with ENSO and EQUINOO, have been studied, and models to better predict the quantity of monsoon rains have been statistically derived.. Second, they help confine the winds to the subcontinent, hampering their northward progress. The temperatures range from a maximum of 29 to 23 degrees centigrade. English: Monsoon rain in Kerala. Over India, a subtropical westerly jet develops in the winter season and is replaced by the tropical easterly jet in the summer season. The monsoon is the primary delivery mechanism for fresh water in the Indian subcontinent. The jet streams are systems of upper-air westerlies.  Therefore, in the context of the monsoon, the two together came to be known as the El Niño-Southern Oscillation (ENSO) effect.  Additionally, farmers rendered jobless by failed monsoon rains tend to migrate to cities. However, the agriculture sector still contributes 17-20% of GDP and is the largest employer in the country, with about 60% of Indians dependent on it for employment and livelihood. Kerala to witness more pre-Monsoon rains March 16, 2017 12:48 PM | Skymet Weather Team Most parts of Kerala have been witnessing dry weather conditions in the month of February. Mid October witnesses the arrival of the Northeast Monsoon. Sometimes, despite average annual rainfall, the daily distribution or geographic distribution of the rain is substantially skewed. Szczególnie silne opady miaÅy miejsce 8 sierpnia. For those who enjoy downpours what better time to be in Kerala than the Monsoon season. , The northeast monsoon usually "bursts" around 20 October and lasts for about 50 days before withdrawing. When the southeast trade winds cross the equator, they are perceived in the Northern Hemisphere as equatorial westerlies because they seem to blow from the equator toward the Tropic of Cancer.  As such, the flora, fauna, and entire ecosystems of these areas rely heavily on the monsoon.  With a positive IOD, winds over the Indian Ocean blow from east to west. Around 65% of the rainfall occurs from June to August corresponding to the Southwest monsoon, and the rest from September to December corresponding to Northeast monsoon.  At least five prediction models exist. Na poczÄ tku sierpnia 2018 stan Kerala nawiedziÅy intensywne opady deszczu. However, geophysical factors like Earth's orbit, its rotation, and its axial tilt cause these belts to shift gradually north and south, following the Sun's seasonal shifts. Since the strength of the monsoon is partially dependent on the temperature difference between the ocean and the land, higher ocean temperatures in the Indian Ocean have weakened the moisture bearing winds from the ocean to the land. Without them, the southwest monsoon winds would blow right over the Indian subcontinent into, For the northeast monsoon, the highlands of the, This page was last edited on 8 January 2021, at 10:29. Monsoon is an ideal time for Ayurvedic treatments in Kerala, it is believed that Ayurveda therapies work best in the rainy season as the pores of the skin opens during this season. Since the Great Famine of 1876–78 in India, various attempts have been made to predict monsoon rainfall. Because of differences in the specific heat capacity of land and water, continents heat up faster than seas. However, the huge landmass of the Himalayas restricts the low-pressure zone onto the Himalayas themselves. South West Monsoon in Kerala : Southwest monsoon is the main rainy season in Kerala. There are some unique features of the rains that the monsoon brings to the Indian subcontinent. To be in Kerala during the Onam festival is a delight. A host of mosquito-borne, water-borne and air-borne infections become more common as a result of the change in the ecosystem. In 2003, IMD substantially changed its forecast methodology, model, and administration. Because more than half of these farmlands are rain-fed, the monsoon is critical to food sufficiency and quality of life. It affects the Indian subcontinent, where it is one of the oldest and most anticipated weather phenomena and an economically important pattern every year from June through September, but it is only partly understood and notoriously difficult to predict. A view of a flooded road after Monsoon rains in Kochi Kerala took lessons from 2018 floods, all set to manage any disaster this monsoon 3 min read.  For example, the strong ENSO of 1997 did not cause drought in India. An early shift results in an early monsoon. , However, a rainy monsoon is not necessarily a normal monsoon – that is, one that performs close to statistical averages calculated over a long period. Most of the coastal rivers of Western India are also rain-fed and monsoon-dependent. In Kerala , people enjoy a very moderate climate. It has a significant effect on the overall well-being of residents and has even been dubbed the "real finance minister of India"..  Walker noticed that the quantity of rainfall in the Indian subcontinent was often negligible in years of high pressure over Darwin (and low pressure over Tahiti). Strength: The strength of the southwest monsoon is determined by the strength of the easterly tropical jet over central India. Meanwhile, there has been a three-fold rise in widespread extreme rainfall events during the years 1950 to 2015, over the entire central belt of India, leading to a steady rise in the number of flash floods with significant socioeconomic losses. Kerala was also flooded in 2018 and 2019 .  A sixteen-parameter monsoon forecasting model used since 1988 was replaced in 2003. This theory tries to explain the establishment of the northeast and southwest monsoons, as well as unique features like "bursting" and variability. The monsoon of South Asia is among several geographically distributed global monsoons. The northward shift is not a slow and gradual process, as expected for most changes in weather pattern.  Further, the two poles of the IOD – the eastern pole (around Indonesia) and the western pole (off the African coast) — independently and cumulatively affect the quantity of monsoon rains. A good monsoon results in better agricultural yields, which brings down prices of essential food commodities and reduces imports, thus reducing food inflation overall. Places like Kerala and the Western Ghats get a large number of tourists, both local and foreigners, during the monsoon season. They give rise to slowly moving upper-air waves, with 250-knot winds in some air streams. This shift is due to the intense heating of the plateau during the summer months. The monsoon turns large parts of India from semi-deserts into green grasslands. Daytime scene showing the pre-monsoon air over India. Kerala has mainly two rainy seasons. The exact criteria for a normal monsoon are defined by the Indian Meteorological Department with calculations for the mean and standard deviation of each of these variables.. But with the advent of globalization, such travel is gaining popularity. The floods resulted in the death of at least 22 people.  Widespread extreme rainfall events are those rainfall events which are larger than 150 mm/day and spread over a region large enough to cause floods. However, invariably Monsoon arrives over the state before or after its normal onset date. And when coupled with the traditional theory (based on the heating of sea and land), it enhances the explanation of the varying intensity of monsoon precipitation along the coastal regions with orographic barriers. As such, it affects the environment (and associated flora, fauna, and ecosystems), agriculture, society, hydro-power production, and geography of the subcontinent (like the availability of fresh water in water bodies and the underground water table), with all of these factors cumulatively contributing to the health of the economy of affected countries.  Places like Kerala and the Western Ghats get a large number of tourists, both local and foreigners, during the monsoon season. Prior to onset of Monsoon, pre-Monsoon weather activities pick up pace and the entire state of Kerala experiences intense rain showers. A strong easterly tropical jet results in a strong southwest monsoon over central India, and a weak jet results in a weak monsoon. The jet stream theory also explains the variability in timing and strength of the monsoon. Also, some mountainous areas, especially in Himalayan regions, get cut off when roads are damaged by landslides and floods during heavy rains. This makes the Arabian Sea (the western Indian Ocean near the African coast) much warmer and the eastern Indian Ocean around Indonesia colder and drier. Third, they contribute to the convergence of the Bay of Bengal branch and Arabian Sea branch of the southwest monsoon winds, increasing the intensity of precipitation over the northern part of the subcontinent. The high temperature during the summer over the Tibetan Plateau, as well as over Central Asia in general, is believed to be the critical factor leading to the formation of the tropical easterly jet over India. A recent assessment of the monsoonal changes indicate that the land warming has increased during 2002–2014, possibly reviving the strength of the monsoon circulation and rainfall. Theories of the mechanism of the monsoon primarily try to explain the reasons for the seasonal reversal of winds and the timing of their reversal.  With around 120â140 rainy days per year,: 80 Kerala has a wet and maritime tropical climate influenced by the seasonal heavy rains of the southwest summer monsoon and northeast winter monsoon.
