BHUBANESWAR: Cyclone Yaas, called to cross the north Odisha-West Bengal coasts involving Paradip and Sagar islands across Wednesday noon because of very severe cyclonic storm, which is going to be the next cyclone in the Bay of Bengal hitting on the East shore in the month of May in 3 decades. The state government has left enormous preparations to guarantee zero casualty amid forecasts that North Odisha areas of Balasore, Bhadrak, Mayurbhanj, Jagatsinghpur and Kendrapada could be badly hit. Earlier this Fani had destroyed large sections of coastal Odisha, seriously battering spiritual funds Puri and state capital Bhubaneswar, later making landfall near Puri on May 3, 2019. This was followed closely by Amphan who left a path of destruction from northern Odisha and caused enormous harm in Kolkata crossing West Bengal shore on May 20, 2020. The two Fani and Amphan were very severe cyclones. This time Odisha expects quite severe cyclonic storm with sustained wind speed of 120 to 165 kilometers per hour, gusting to 180 kilometers, deep rainfall of 300 mm and storm surge of 3 to 4.5 meters. After Fani struck Odisha, it was subsequently termed among the rarest of summer cyclones, the initial one in 43 years to strike Odisha and among the three to strike the country in the past 150 years using a wind speed of 200 km/hour. But, summer cyclones have gotten regular then for the forthcoming three decades. U C Mohantya professor in School of Earth, Ocean and Climate Sciences, IIT Bhubaneswar, that has performed extensive study on tropical cyclones, ” said that the three May cyclones in 3 years could be mere coincidence. But, increase in seriousness of current cyclones appears to be attributed to global warming. The Bay of Bengal has seen approximately 15 to 20 cyclones in May from the previous 120 decades. “The complete amount of cyclones in the Bay isn’t considerably increasing. On the other hand, the intensity of cyclone is climbing,” he explained. Mohanty said that there are just two cyclone seasons at the Bay of Bengal: April-May-June along with October-November-December. The majority of the cyclones occur in October followed by May. The Bay of Bengal is normally warmer in May. The IIT scientist said that the cyclones are getting more ferocious since global warming is leading to the moisture content from the air, that is the power supply for virtually any cyclone. Oceans are comparatively warmer, leading to additional evaporation. In the same way, moisture holding ability of air is rising because of warming, which makes the tropical cyclones more extreme, ” he explained. Sarat Chandra Sahudirector of the Centre for Environment and Climate (CEC), SOA University, who’s also a former manager of IMD Bhubaneswar, stated summer cyclones have become prevalent both at the Arabian Sea and West Bengal due to global warming because of climate change. The ocean surface temperature has to be minimal 26.5°C for cyclones to sort, aside from other things. The fever is currently around 30°C into 31°C. “The sea surface is assisting transport of vapour and heat out of the sea into overlying atmosphere for cyclone formation. Low stresses are more frequently turning into cyclones because of favourable states,” Sahu stated. Particular relief commissioner (SRC) Pradeep Jena stated Odisha has created preparations for potential landfall in the nation considering prediction by climate channels and specialized inputs from IMD. “Extensive preparations are created for evacuation of individuals from low-lying bubbles, storm surge regions and exposed families,” he explained.
Following Fani & Amphan, Odisha braces for third cyclone in 3 Decades
