caption_attribution_description: English: This map shows the tracks of all tropical cyclones in the 2020 North Indian Ocean cyclone season. The points show the location of each storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir-Simpson Hurricane Scale (see below), and the shape of the data points represent the type of the storm. &#160;Map generation parameters: --res 4000 --extra 1 --dots 0.2 --lines 0.04 --xmin 40 --xmax 100 --ymin 0 --ymax 35 Saffir–Simpson scale Tropical depression≤38 mph≤62 km/h Category 3111–129 mph178–208 km/h Tropical storm39–73 mph63–118 km/h Category 4130–156 mph209–251 km/h Category 174–95 mph119–153 km/h Category 5≥157 mph≥252 km/h Category 296–110 mph154–177 km/h Unknown Storm type Tropical cyclone Subtropical cyclone Extratropical cyclone / Remnant low / Tropical disturbance / Monsoon depression
context_page_description: The 2020 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and November, with peaks in May and October. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on May 16 with the designation of Depression BOB 01 in the Bay of Bengal, later to become Super Cyclonic Storm Amphan, one of the strongest storms in the bay recorded and the costliest storm on record in the basin.
  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; and the Bay of Bengal to the east, abbreviated BOB by the IMD.
  The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department, while the Joint Typhoon Warning Center releases unofficial advisories.
