The 2020 North Indian Ocean Cyclone Season was a hyperactive and catastrofic season in the annual cycle of tropical cyclone formation. This season produced eight named storms, of which five intensified into a very severe cyclonic storm. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began with the formation of the deep depression BOB 01 on May 3, and ended in November 29 with the dissipation of Khai-Muk
The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD. The official Regional Specialized Meteorological Centre in this basin is the IMD, while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. On average, three to four cyclonic storms form in this basin every season.
Within this basin, a tropical cyclone is assigned a name when it is judged to have reached Cyclonic Storm intensity, with winds of 65 km/h (40 mph). The names were selected by members of the ESCAP/WMO panel on Tropical Cyclones between 2000 and May 2004, before the nal Specialized Meteorological Center in New Delhi started to assign names in September 2004. There is no retirement of tropical cyclone names in this basin, as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from the Western Pacific, then it will retain its original name. The next nine available names from the List of North Indian Ocean storm names are below.
