Weather Systems Over the Country

A low-pressure area formed over the southeast Bay of Bengal at 5:30 a.m. IST on 13 November under the influence of an upper-air cyclonic circulation over the central Andaman Sea and adjoining Andaman and Nicobar Islands. The associated cyclonic circulation extends into the middle troposphere. The system is likely to move northwestwards and intensify into a well-marked low-pressure area around 14 November and a depression around 15 November over the same region.

The Western Disturbance persists as a cyclonic circulation over the Kashmir division and adjoining areas at 3.1 km above mean sea level. Its associated trough in the mid-tropospheric westerlies, with an axis at 5.8 km above mean sea level, now runs roughly along longitude 73°E, north of latitude 32°N.

The upper-air cyclonic circulation over the southeast Bay of Bengal, which extended up to 1.5 km above mean sea level, has merged with the circulation associated with the newly formed low-pressure area.

An upper-air cyclonic circulation persists over Sikkim and adjoining areas at 3.1 km above mean sea level. A trough at the same level extends from this circulation to the northwest Bay of Bengal across Bangladesh and Gangetic West Bengal.

An upper-air cyclonic circulation persists over the southeast Arabian Sea and adjoining south Lakshadweep area at 1.5 km above mean sea level. Another circulation persists over the Gulf of Mannar and adjoining areas at 0.9 km above mean sea level.
