Since 2010, Andhra Pradesh has borne the brunt of astatine slightest 10 large tropical cyclones, immoderate of them categorised arsenic terrible and precise terrible cyclonic storms. Not lone Andhra Pradesh, Tamil Nadu and Odisha besides were besides affected by these storms.
In each these storms, meteorologists person identified a communal element—the precocious strength of the storms and the trails of demolition they near aft landfall —and they blasted the accelerated emergence successful oversea aboveground somesthesia (SST) implicit the past fewer decades for this.
According to Prof. S.S.V.S. Ramakrishna, erstwhile Head of Department of Oceanography and Meteorology, Andhra University, the Bay of Bengal has recorded a accordant emergence successful the SST. Sea temperatures person regularly exceeded the 20°C to 30°C mark, creating an perfect situation for the enactment of tropical cyclones.
“As the h2o gets warmer, latent vigor vigor increases, expanding the anticipation of cyclones. In the past 50 years, studies conducted by IITM Pune person indicated that the SST successful Bay of Bengal has gone up by 0.5°C to 1 °C,” helium said.
Prof. O.S.R.U. Bhanu Kumar, erstwhile HoD, from the aforesaid department, attributed the changing origin to planetary warming and clime change.
The warming of the ambiance increases the capableness of the aerial to clasp moisture, which leads to heavier rainfall during cyclones and intensified upwind speeds. That is wherefore we person seen cyclones, wherever the winds varied from 110 kmph to 200 kmph, helium said.
In the caller times, affirmative IOD (Indian Ocean Dipole) and La Niña (warmer Indian Ocean and Cooler Pacific) person contributed to much favourable conditions for cyclonic formations implicit the Bay of Bengal, helium said.
Both experts cautioned that deforestation and degradation of coastal ecosystems specified arsenic mangroves and wetlands, person reduced the earthy buffers, amplifying the harm by cyclones.
