to the west of India. The official
Regional Specialized Meteorological Centre in this basin is the
India Meteorological Department (IMD), while the
Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians
45°E and
100°E are included in the season by the IMD.
Sixteen depressions developed during the 1950 season, with four of them becoming cyclonic storms while three of them formed over the land. Most tropical cyclones formed in this season are weak, as there is no severe cyclonic storms formed during this season.
