  • Cyclone Tauktae
    Cyclone Tauktae What is the issue? The recent Cyclone Tauktae has left a trail of death and destruction before making landfall in Gujarat. This reminds again that accurate forecasts and resilience-building hold the key to handling severe cyclones. How severe was Cyclone Tauktae? Cyclone Tauktae swelled into an extremely severe cyclonic storm. It led to dumping enormous volumes of water all along the west coast. The cyclone caused loss of life in Kerala, Karnataka, Goa, Maharashtra and Gujarat, before weakening overland. The twin crises of the cyclone and COVID-19 have strained the capacities of multiple States, especially the coastal ones. What are IMD’s recent measures? In 2020, the India Meteorological Department (IMD) launched an impact- based cyclone warning system. This was designed to reduce economic losses by focusing on districts and specific locations. It incorporates such factors as population, infrastructure, land use and settlements. The IMD also claimed that its accuracy of forecasts, for instance, in plotting landfall location, is now better. Together with ground mapping of vulnerabilities, this is a promising approach to avoid loss of life and destruction of property. What are the priorities now? Developing greater expertise in forecasting and disaster mitigation is essential. Crafting policies to increase resilience among communities is another priority. Arabian Sea has emerged as a major source of severe cyclones. Their intensity is aggravated by long-term rise in sea surface temperatures linked to pollution over South Asia and its neighbourhood. So importance of precise early warnings is high now than before. Climate-proofing lives and dwellings is also a high priority now.

  • Cyclone Tauktae
    Cyclone Tauktae drishtiias.com/printpdf/cyclone-tauktae Why in News Recently, Cyclone Tauktae made landfall in Gujarat. The cyclone has left a trail of destruction as it swept through the coastal states of Kerala, Karnataka, Goa and Maharashtra. Key Points 1/3 About: Named by: It is a tropical cyclone, named by Myanmar. It means 'gecko', a highly vocal lizard, in the Burmese language. Typically, tropical cyclones in the North Indian Ocean region (Bay of Bengal and Arabian Sea) develop during the pre-monsoon (April to June) and post-monsoon (October to December) periods. May-June and October-November are known to produce cyclones of severe intensity that affect the Indian coasts. Classification: It has weakened into a "very severe cyclonic storm" from the "extremely severe cyclonic storm". The India Meteorological Department (IMD) classifies cyclones on the basis of the maximum sustained surface wind speed (MSW) they generate. The cyclones are classified as severe (MSW of 48-63 knots), very severe (MSW of 64-89 knots), extremely severe (MSW of 90-119 knots) and super cyclonic storm (MSW of 120 knots or more). One knot is equal to 1.8 kmph (kilometers per hour). Developed in Arabian Sea: Tauktae is the fourth cyclone in consecutive years to have developed in the Arabian Sea, that too in the pre-monsoon period (April to June). After Cyclone Mekanu in 2018, which struck Oman, Cyclone Vayu in 2019 struck Gujarat, followed by Cyclone Nisarga in 2020 that struck Maharashtra. All these cyclones since 2018 have been categorised either ‘Severe Cyclone’ or above. Arabian Sea becoming Hotbed of Cyclones: Annually, five cyclones on average form in the Bay of Bengal and the Arabian Sea combined.

  • Arabian Sea and Cyclone Tauktae
    Cyclone Tauktae A low-pressure area over the Arabian Sea first concentrated into a depression and later intensified into a cyclonic storm named ‘Cyclone Tauktae’. The West Coast of India has been affected by the cyclone. It is the first cyclone of 2021. Some brief facts about Tauktae Cyclone for the IAS Exam are given below: What kind of a It is a tropical cyclone, termed as ‘Extreme Severe Cyclonic Storm’ (ESCS) and cyclone is Tauktae? ‘Very Severe Cyclonic Storm’ (VSCS) What is the meaning It means ‘Gecko’ (in Burmese Language) which is a highly vocal lizard of the name ‘Tauktae’? Which country has Myanmar has named this cyclone ‘Tauktae’. given the name ‘Tauktae’? How are cyclones 13 countries of the World Meteorological Organization/United Nations Economic named? and Social Commission for Asia and the Pacific (WMO/ESCAP) Panel on Tropical Cyclones (PTC) name the cyclones In 2020, the following cyclones hit the Indian regions: 1. Cyclone Nisarga 2. Cyclone Amphan Arabian Sea and Cyclone Tauktae Due to global warming Arabian Sea has been warming up in recent years and Cyclone Taukate is the fourth cyclone in consecutive years to have originated from the sea. Typically, out of the average of five cyclones that develop annually in the Bay of Bengal and Arabian Sea region, four are formed over the Bay of Bengal (It being warmer than the Arabian Sea). The warmer temperature supports active convection, heavy rainfall, and intense cyclone activity. However, Arabian Sea water too is warming up which provides an ample amount of energy that enables the intensification of tropical cyclones.

    CHAPTER 3 Hotspots of exposure to cascading risks 44 ChApTER 3: Hotspots OF EXpOsURE to CAsCAdInG RIsks he devastating impacts of the COVID-19 pandemic along with the frequent occurrence of other biological and natural hazards combined with the effects of climate change, Thas placed millions more people at risk. A set of hotspots have emerged under these new and converging risk parameters. Countries in these hotspots need to capture the impact of systemic and cascading risks and highlight priority areas for action. The Asia-Pacific Disaster Report 2019 presented, for the first time, a riskscape that included slow-onset disasters along with floods, tropical cyclones, earthquakes, and tsunamis. However, the risks have expanded with the addition of biological hazards and the impacts of climate change that are occurring simultaneously. Thus, the riskscape now needs to include a new set of complex parameters. The Asia- Pacific Disaster Report 2021 combines, for the first time, data on biological hazards, natural hazards and climate change to identify hotspots where people are simultaneously exposed to multiple risks. These hotspots are listed below: • East and North-East Asia — where heatwaves and related biological hazards are increasing along with the existing riskscape of earthquakes and tropical cyclones. • North and Central Asia — where high per capita rates of COVID-19 are being superimposed on new areas of drought and biological hazards due to climate change. • South and South-West Asia and South-East Asia — as one of the global epicentres of COVID19, the pandemic here is being superimposed on floods, droughts, and cyclones, that are being exacerbated by climate change and leading to systemic failures.

  • Earth Newsletter May-June
    J.B.BODA May-June 2021 Cyclone Risk in India The extensive coastal belt of India is very vulnerable to the deadly storms known as tropical cyclones. About 4 to 6 such storms originate in the Bay of Bengal and the Arabian Sea every year. Tropical cyclones, which are characterised by torrential rain, gales, and storm surges, cause heavy loss of human lives and destruction of property. They also result in extensive damage to standing crops and loss of cattle. The Bay of Bengal cyclones more often strike Odisha-West Bengal coast in October, Andhra coast in November and the Tamil Nadu coast in December. Over 60 percent of the events in the Bay of Bengal strike dierent parts of the east coast of India, 30 percent strike coasts of Bangladesh and Myanmar, and about 13 percent dissipate over the sea itself. The cyclones crossing dierent coastal states are shown in Fig.1. Considering Arabian Sea, a significant number of cyclones dissipate over the sea itself before making any landfall (about 48.5%). Gujarat coast is the most prone for the cyclones developing over the Arabian Sea, with about 23% of total cyclones developing over the Arabian Sea, crossing the Gujarat coast, and 11% each crossing the Pakistan and Oman coasts. Fig.1 (a) Frequency of cyclones/severe cyclones over the Bay of Bengal landfalling over different coastal states during 1891-2019. Fig.1 (b) Frequency of cyclones/severe cyclones over the Arabian Sea landfalling over different coastal states during 1891-2019. Kindly note that the monitoring system over the region has undergone several changes with augmentation of surface observatories, introduction of RS/RW observations during the 1930’s, use of satellites since the 1960s, and implementation of meteorological buoys since 1997.

  • A CLIMATE RISK: the HINDU EDITORIAL on EXTREME WEATHER EVENTS Relevant For: Environment | Topic: Environmental Conservation, Sustainable Development, and EIA
    Source : www.thehindu.com Date : 2021-07-26 A CLIMATE RISK: THE HINDU EDITORIAL ON EXTREME WEATHER EVENTS Relevant for: Environment | Topic: Environmental Conservation, Sustainable Development, and EIA The monsoon is nearing its halfway mark and July, which is among the rainiest months, began with a rainfall deficit but has since seen a revival. For most of last week, all-India rainfall has been over 50% more than what is normal for this time of the year. Many regions in the Konkan coast and the southern peninsula have been seeing instances of extreme rainfall. According to India Meteorological Department (IMD) data on the regional distribution, the ‘South Peninsula’ has seen 29% more rain from June 1-July 25 than what is normal for this period. Rainfall in Mahabaleshwar, Maharashtra, was torrential enough to beat its all-time record, according to the IMD. The monsoon is characterised by unexpected variability that forecast models can capture only in a limited way. However, much evidence is accumulating that there is a distinctive change in climate patterns. The frequency and the strength of cyclones over the Arabian Sea have increased in the last two decades. There has been a 52% increase in the frequency of cyclones over the Arabian Sea from 2001-2019 and an 8% decrease over the Bay of Bengal compared to 1982-2002, when, historically, most cyclones have been in the Bay of Bengal, according to a new study in Climate Dynamics. Even the duration of these cyclones has increased by 80%. More cyclones are bringing in more moisture from the Arabian Sea and contributing to extreme rainfall events over the western coast, the most recent example being cyclone Tauktae in May, which at 185 kilometres per hour was among the strongest cyclones to approach Mumbai.
