North Indian Ocean tropical cyclone
type of tropical cyclone located in North Indian Ocean and measured by India Meteorological Department (IMD) scale
In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December.
The North Indian Ocean is the least active official basin, contributing only seven percent of the world's tropical cyclones. However the basin has produced some of the deadliest cyclones in the world, since they strike over very densely populated areas.
The Regional Specialized Meteorological Centre (RSMC) is the India Meteorological Department (IMD) and it is responsible to monitor the basin, issues warning and name the storms.
Sub-basins
The basin is divided into two sub-basins – the Bay of Bengal and the Arabian Sea.
The Bay of Bengal, located in the northeast of the Indian Ocean. The basin is abbreviated BOB by the India Meteorological Department (IMD). The United States's Joint Typhoon Warning Center unofficially designates as B to classify storms formed in the Bay of Bengal. The Bay of Bengal's coast is shared among India, Bangladesh, Myanmar, Sri Lanka and western part of Thailand. This sub-basin is the most active and produces some of the deadliest cyclones of all time.

Why this record matters
“North Indian Ocean tropical cyclone” is worth following because a concise public description often conceals a longer documentary argument. Here, North, Indian and Ocean provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q27491739. None of the 0 selected statements returned an explicit reference.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
