A cyclone is a large mass of air that rotates around a Low-pressure center, usually originating over oceans. They rotate clockwise in the southern hemisphere, south of the equator, and counterclockwise in the northern hemisphere if viewed from above. Let’s find out who names the cyclones in India and what is the meaning of cyclone Yaas.
A typical cyclone was formed due to disturbances over the Indian Ocean, during the Monsoon season in India. The Indian meteorological department first monitored it on May 23. The conditions in the basin favored development as the cyclonic system turned into a deep depression later in the day before intensifying into a cyclone storm the next day, getting the name Yaas.
This High damaging tropical cyclone made way into Odisha and adjoining regions of West Bengal on 27th May and caused havoc.
Naming a Cyclone in North Indian Ocean (45°E – 100°E)
Within the North Indian Ocean region (45°E – 100°E), tropical cyclones are named by the India Meteorological Department (IMD, New Delhi). This happens when they qualify for having intensified into the cyclonic storms with 3-minute sustained wind speeds of at least 34 knots or 39 mph or 63 km/h. If a cyclonic storm moves into the basin from the Western Pacific, then it will keep its original name and IMD doesn’t name it. However, if the cyclone weakens into a deep depression and later reintensifies after moving into the Indian Ocean region then it is assigned a new name by the IMD.
After Cyclone Amphan made its headway into the region in May 2020, it exhausted the list of names that were originally kept from 2004. In May 2020, A new list of names was prepared and will be used in alphabetical order for storms after Amphan. Cyclones names like Nisarga, Gati, Nivar, Burevi, Tauktae were taken from this list.
