ABSTRACT The Cyclone is right now classified as a “Very Severe Cyclonic Storm” and is the fifth-most cyclone twister ever in written history in the “Arabian Sea”. It started in the “Arabian Sea” and was first seen by the Indian Meteorological Department on 13th May moving toward the east, and afterward consequently north, while heightening. The tempest moved along the shoreline of Karnataka on 15th May, starting a fast increasing from a “Serious Cyclonic Storm” to a “Exceptionally Severe Cyclonic Storm”, and afterward to an “Incredibly Severe Cyclonic Storm”. The IMD classifies tropical storms into 7 different types, which rotates in an anti-clockwise direction into “Depression”, “Deep Depression”, “Cyclonic Storm”, “Severe Cyclonic Storm”, “Very Severe Cyclonic Storm”, “Extremely Severe Cyclonic Storm”, and “Super Cyclonic Storm”. The last two have wind rates of more than 160 kmph and 220 kmph, separately. Keywords: Tauktae, Strom, Rain, Cyclone, Data, Satellite Images. I. INTRODUCTION India was pummelled on seventeenth May 2021 by the strongest storm on record to arrive at its west coast, hampering specialists' reaction to the Covid-19 (Khandelval, 2020; Soni et al., 2020; U Pandya, 2020) & Mucormycosis (Khandelval, 2021) emergency in a portion of the country's hardest hit areas. Typhoon Tauktae, a tempest with wind speeds identical to a high-end Category 3 tropical storm that was formed in the "Arabian Sea '', made landfall on seventeenth May 2021 night neighbourhood time in Gujarat. It reinforced marginally as it hit the western state with most extreme supported breezes of 205 kilometers each hour (125 mph), as per the United States' “Joint Typhoon Warning Center”. The word cyclone is accepted to have come from the Greek word kyklon which signifies “moving in a circle” or “whirling around”. This is because a cyclone contains high winds which rotate, or “whirl around” a central point. A twister is a space of shut, roundabout smooth movement pivoting a similar way as the Earth (Willis, 2010; Zou). Coriolis force is considered answerable for the turn of cyclones (Deo et al., 2012). The Coriolis Effect is brought about by the pivot of the Earth and the inactivity of the mass encountering the impact. Just the level part of the Coriolis force is by and large significant. In the Northern Hemisphere due to Coriolis force air stream begin spinning anticlockwise around low pressing factor region prompting development of cyclone Similarly in the southern Hemisphere the feeling of spinning of air stream is clockwise in the cyclone (Laan et al., 2017; Lydolph, 1985; van der Laan et al., 2016). Be that as it may, no cyclone is shaped at equator in light of the fact that Coriolis power is zero at the equator. Coriolis power is tiny, and its effects generally become perceptible just for movements happening over huge distances and significant stretches of time, like huge scope development of air in the climate or water in the sea. “Over the warm ocean”, water dissipates and forms mists. In the event that there is low gaseous tension where the mists are shaped, pulls them in and they begin to turn. It is the Coriolis power that makes the tornado's mists turn. Mists will continue to shape and begin turning more. It's the stage when it can shape into a foster tropical storm or lose its power Once twisters appear over land, their fortitude weakens and they begin to become dim. This is because of the absence of dampness and warmth compared with the sea over which it was formed. www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [249] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:08/August-2021 Impact Factor- 5.354 www.irjmets.com Cyclone Tauktae mean Tornado Tauktae (articulated as Tau'Te) got its name from India's adjoining nation Myanmar, which signifies "Gecko", Gecko is an exceptionally vocal lizard in Burmese dialect. Cyclone Naming Global bodies like “World Meteorological Organisation” (WMO), “United Nations Economic” and “Social Commission” for “Asia”, and the ‘Pacific give names to cyclones’. Besides, “Regional Specialised Meteorological Centres” (RSMC), as well as ‘Tropical Cyclone Warning Centres’, also prepare the names of cyclones. The “Indian Meteorological Department” “(IMD) is among six RSMCs in the world that have been mandated to name tropical cyclones in the north Indian Ocean region (Rathore et al., 2017)”. The ‘WMO’ and ‘UN ESCAP’ comprises (1)India (2)Myanmar (3)Bangladesh (4)Sri Lanka (5)Thailand (6)Pakistan and (7)Oman. In 2018, the “WMO” and “ESCAP” included five more countries (1)Iran (2)Qatar (3)Saudi Arabia (4)United Arab Emirates, and (5)Yemen. Last year, the ‘IMD’ released a list of 169 new cyclones, which were suggested by 13 countries. The cyclone is named to make it simpler for individuals to recollect and recognize the tempests. With a name, it is not difficult to make awareness and to convey cautions, and eliminate disarray where there are numerous cyclonic frameworks over an area. The next cyclone will be called 'Yaas', a name given by Oman. From that point forward, cyclone 'Gulab' will make landfall around there. Pakistan has recommended cyclone Gulab's name. According to the IMD, the cyclone that are probably going to hit the area in the coming months incorporate ‘Shaheen (the name given by Qatar)’, ‘Jawad (the name given by Saudi Arabia)’, ‘Asani (a name recommended by Sri Lanka)’, ‘Sitrang (a name proposed by Thailand)’, ‘Mandous (a name recommended by UAE)’, and ‘Mocha (a name proposed by Yemen)’. “NOAA Historical Hurricane Tracks database” 1. 125 mph, May 20, 1999, Cyclone 02A/ARB 01, Gujarat State, India 2. 125 mph, May 17, 2021, Cyclone Tauktae, Gujarat State, India 3. 120 mph, June 3, 2010, Cyclone Phet, Oman 4. 120 mph, June 9, 1998, Cyclone 03A/ARB 02, Gujarat State, India 5. 105 mph, June 6, 2007, Cyclone Gonu, Oman Figure 1.1 - As per the IMD, the track and intensity of the Cyclone Tauktae are given below: www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science [250] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:08/August-2021 Impact Factor- 5.354 www.irjmets.com Image Source – IMD Figure 1.2 - Winds of Cyclone Tauktae from synthetic aperture radar (SAR) at 1:03 UTC, May 17, 2021.

    NASA analyzes powerful Cyclone Chapala's rainfall over the Arabian Sea 30 October 2015 UTC (10:56 a.m. EDT). GPM's rainfall data from the first pass showed that Chapala was close to hurricane intensity as the GMI instrument clearly showed the location of a developing eye. By the second pass Chapala's maximum sustained winds were estimated at 65 knots (75 mph) making it a category one on the Saffir-Simpson hurricane wind scale. Rainfall rates were derived from data collected by GPM's Microwave Imager (GMI) and Dual- Frequency Precipitation Radar (DPR) instruments. GPM's GMI instrument found precipitation around the small tropical cyclone to be only light to moderate. Rain near the center was measured falling at a rate of slightly more than 28 mm (1.1 The MODIS instrument aboard NASA's Aqua satellite inches) per hour with the first pass and 31.9 mm got a good look at the eye of Tropical Cyclone Chapala (1.3 inches) per hour in the second examination. in the Arabian Sea on Oct. 30 at 09:10 UTC (5:10 a.m. GPM is a joint mission between NASA and the EDT).

The Panel on Tropical Cyclones is a regional body jointly established by WMO and ESCAP. The main objectives of the Typhoon Committee and the Panel on Tropical Cyclones are to promote measures to improve tropical cyclone warning systems in the north-western Pacific Ocean, and in the Bay of Bengal and the Arabian Sea, respectively. They develop activities under three substantive components, namely disaster risk reduction, hydrology and meteorology, as well as in the areas of training and research. The present document summarizes key information from the reports on the forty-third session of the Typhoon Committee and the thirty-eighth session of the Panel on Tropical Cyclones in order to provide an overall picture of the framework of cooperation. The document describes actions which could enhance the effectiveness of collaboration with regard to the management of disaster risk reduction related to typhoons and tropical cyclones, in particular the socio-economic impacts of such disasters. The Committee on Disaster Risk Reduction may wish to provide the Typhoon Committee and the Panel on Tropical Cyclones with guidance on their future actions, particularly with regard to obtaining the support of international organizations and funding sources, and developing partnerships with other organizations.
  • Cyclone Tauktae

    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.

Muni Krishna Teaching Associate & Young Scientist, Dept of Meteorology and Oceanography, Andhra University Visakhapatnam, India; Tel: +91-891-2717663 Email: [email protected] KEY WORDS: Winds, upwelling, cyclone, mixed layer, ekman pumping. ABSTRACT Arabian Sea is more vulnerable to cyclonic systems during the recent decades, the intensity (cat 4 or 5) of cyclone systems are increased due to the effect of global warming. It is essential to study the upper ocean changes during the cyclone period. In the present study focuses on the upper ocean changes during the Phet super cyclone (31 May – 7 June 2010). Multi satellite data provide inimitable opportunity to explore upper ocean rejoinders along the long track of major super cyclonic storm Phet. Two large areas of maximizing upwelling and surface cooling (2 – 6°C) are observed along the track. The first cooling area is looks like a cold tongue and it is approximately 350 km. This is a unique feature and also first time observed in the Arabian Sea. The mixed layer and the depth of 20°C isotherm are deepening 54 m and 2m respectively after the passage of Phet. 1. INTRODUCTION Tropical cyclones seldom assault the Oman coast during summer and may change greatly the ocean conditions. They depend on the ocean for their energy supply. Observations have shown that the state of the ocean has a great influence on the intensities, structures and even paths of tropical cyclones (Fisher, 1958; Tisdale and Clapp, 1963; Perlroth, 1967 and Brand, 1971; Black, 1977; Chang and Anthes, 1979) and also capable of altering the upper layers of the ocean.
