High Quality Content by WIKIPEDIA articles! The 2012 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. 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 India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. This timeline includes information that was operationally released, meaning that data from post-storm reviews by the IMD, such as a storm that was not operationally warned upon, has not been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, and dissipations during the season.
