cyclone that was formed in bay of bengal in may 2017
2017 North Indian Ocean cyclone season The season officially had an early start compared with the last two seasons, with the formation of Cyclone Maarutha over the Bay of Bengal in mid-April. Cyclone Mora, formed in late May over the Bay of Bengal. At its peak intensity, it was equivalent to a marginal Category 1 hurricane on the Saffir-Simpson hurricane wind scale. The cyclone produced severe flooding across Sri Lanka, India, Myanmar and Bangladesh and caused 15 deaths directly and 208 deaths indirectly. The floods persisted in Bangladesh since a Deep Depression over Bay of Bengal made landfall and killed 156 people in Bangladesh. A depression formed in northwestern Bay of Bengal and produced torrential rainfall. It was followed by a depression over Jharkhand which killed 70 people in West Bengal. Under the influence of strong monsoon surge a disturbance developed over Bay of Bengal travelled westwards and intensified to an unnamed depression. It also affected neighboring Karachi in Pakistan. A strong monsoon surge prevented formation of systems until a deep depression formed over West Bengal in October and caused heavy rainfall. A couple of depression formed between mid October and November which continued the rain spell causing destruction of life and property. Very Severe Cyclonic Storm Ockhi formed in early December and wreaked havoc in the countries where it impacted. It was equivalent to a strong Category 3 hurricane on the Saffir-Simpson scale at peak intensity. The twin storm of Ockhi was a deep depression which originated in Bay of Bengal while its counterpart was in Arabian Sea.
History of tropical cyclone naming At the 22nd hurricane committee in 2000 it was decided that tropical cyclones that moved from the Atlantic to the Eastern Pacific basin and vice versa would no longer be renamed.[51] Ahead of the 2000–01 season it was decided to start using male names, as well as female names for tropical cyclones developing in the South-West Indian Ocean.[52] RSMC La Reunion subsequently proposed to the fifteenth session of the RA I Tropical Cyclone Committee for the South-West Indian Ocean during September 2001, that the basin adopt a single circular list of names.[53] Along with the RA V Tropical Cyclone Committee, RSMC La Reunion also proposed to the session that a tropical cyclone have only one name during its lifetime.[53] However, both of these proposals were rejected in favour of continuing an annual list of names and to rename systems when they moved across 90°E into the South-West Indian Ocean.[53] During the 2002 Atlantic hurricane season the naming of subtropical cyclones restarted, with names assigned to systems from the main list of names drawn up for that year.[54]
