The eighth depression and fourth named storm of the 2020 North Indian Ocean cyclone season, Nivar originated from a disturbance in the Intertropical Convergence Zone. Interannual variability is quite high in each basin, but fluctuations in opposite directions between different oceans generally compensate for local variations. The storm system is likely to move northwestwards and weaken into low pressure. It only lasted for a short amount of time. Chennai and other parts of North TN saw gusty winds touching 60-70kmph on 24,25 November. When tropical storms form over the Northwest Pacific Ocean, they become typhoons. Sometimes, gaps between the rainbands leave areas within the storm with no rain or wind. discuss the stage of development of the tropical cyclone nivar The scale proposed in 1977 by the Americans H.S.

University of Reading and Royal Meteorological Society. It is the largest singular and specialised disaster force in the world. A very large part of the energy of cyclones comes from evaporation at the ocean surface, forced by winds of increasing intensity. Today thousands of aspirants have joined the elite services such as IAS, IPS, IFS, IRS and other central and state services with the right inputs provided by ForumIAS. According to the definition of the World Meteorological Organization (WMO), tropical cyclones are atmospheric disturbances of a few hundred kilometres wide scale, originating over tropical or sub-tropical waters and presenting an organized thunderstorm activity and a cyclonic circulation[1], more intense at the surface than at altitude. When an area of disturbed weather in the tropics causes a moving area of thunderstorms, everyone pays a bit closer attention.
