A growing number of cyclones are experiencing multiple rapid intensification globally where a tropical cyclone intensifies dramatically in a short period like an increase in the cyclone’s intensity of 30 knots speed or more in 24 hours and this poses significant challenges to cyclone forecasting, said scientists of the Indian National Centre for Ocean Information Services (INCOIS).
In the latest study conducted in collaboration with researchers from Department of Meteorology and Oceanography, College of Science and Technology, Andhra University, Visakhapatnam, the scientists have deduced that global warming has heightened cyclone intensity, multiple rapid intensifications leading to unpredictability of cyclone behaviour.
“We have observed that tropical cyclones are intensifying rapidly and frequently. We also found changes in their lifecycles. Previously, this rapid intensification used to occur during initial stages of cyclones’ life, but now, with ocean warming, it is occurring even in the mature stages,” explained first author and INCOIS scientist N. D. Manikanta.
