1980–1984 North Indian Ocean cyclone seasons


1980–1984 North Indian Ocean cyclone seasons

The years from 1980-1984 featured the 1980-1984 North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.

1980 North Indian Ocean cyclone season

Tropical Storm One (1B)

The first storm of the season began its life on October 10 in the Bay of Bengal. It executed an anticyclonic loop to the west, and became a tropical storm before hitting eastern Sri Lanka on the 17th. It continued westward, and ultimately dissipated over the Arabian Sea on the 20th.

Unknown Two (2B)

On October 18, a storm of unknown intensity hit eastern India, dissipating the next day.

Tropical Storm Three (3A)

The monsoon trough spawned a tropical depression off the western Indian coast on November 12. It tracked generally northwestward, slowly organizing into a tropical storm on the 17th. The storm turned to the northeast, where it dissipated over the northeastern Arabian Sea.

Unknown Storm Four (4B)

A storm of unknown intensity persisted in the western Bay of Bengal from December 3 to the 7th, remaining well offshore of any landmass.

Tropical Storm Five (5B)

The last storm of the season formed in the central Bay of Bengal on December 12. It moved east-southeastward, then turned to the west where it briefly became a tropical storm. The storm struck eastern Sri Lanka, and dissipated over the island on the 17th.

1981 North Indian Ocean cyclone season

Tropical Storm One (1B)

The monsoon trough spawned a tropical depression just east of Sri Lanka on October 25. The depression tracked northwestward, becoming a tropical storm on the 27th over southern India. Over the Arabian Sea, it turned northeastward where, after reaching a peak of 70 mph winds, it hit western India on the 2nd.

Cyclone Two (2B)

On November 20, Tropical Storm Two, having weakened from a cyclone that developed on the 17th, hit Bangladesh and dissipated soon after.

Cyclone Three (3B)

Cyclone Three, which formed from the monsoon trough in the Bay of Bengal on December 5, reached a peak of 85 mph winds on the 9th. It weakened as it continued northward, and hit near the Indian/Bangladesh border on the 10th as a 60 mph tropical storm. Widespread damage and flooding caused at least 92 fatalities.

1982 North Indian Ocean cyclone season

Cyclone One (1B)

On April 30 the monsoon trough spawned a tropical depression in the western Bay of Bengal. It tracked northeastward, becoming a tropical storm on the 1st and a cyclone on the 2nd. Its movement became more to the east, and the cyclone continued to quickly intensify, reaching a peak of 145 mph winds just before landfall. The small and compact cyclone hit southern Myanmar on the 4th, and it dissipated the next day over land. Moderate to heavy damage was experienced, but advanced warning kept the death toll at only five in an area where hundreds to thousands of deaths are relatively common.

Tropical Storm Two (2B)

Tropical Depression 2B developed from the monsoon trough in the central Bay of Bengal on May 30. It headed northeastward, becoming a tropical storm later that day and reaching a peak of 65 mph winds on the 31st. The storm turned to the northwest, where it weakened to a tropical depression. It restrengthened, and hit near Paradip, India on the 3rd as a 65 mph tropical storm. The storm brought heavy flooding amounting to 140 casualties and destroying over 500,000 homes.

Tropical Storm Three (3B)

Tropical Storm Three, which formed in the central Bay of Bengal on October 13, hit eastern India on the 16th as a 60 mph tropical storm.

Tropical Storm Four (4B)

An area of convection south of the previous storm slowly organized into a tropical storm on October 17. It tracked northwestward, reaching a peak of 60 mph winds before hitting southeastern India on the 18th as a weakened 50 mph storm. 5 casualties can be attributed to this system.

Cyclone Five (5A)

The final storm of the season developed on November 4 in the central Arabian Sea. It tracked northeastward, strengthening into a tropical storm on the 6th and a cyclone on the 7th. The system peaked at 95 mph winds before hitting Veraval, India on the 8th. The cyclone rapidly dissipated, after resulting in 341 casualties and heavy flooding.

1983 North Indian Ocean cyclone season

Tropical Storm Aurora (1A)

On August 9 a tropical depression developed in the northwest Arabian Sea. It tracked westward, becoming a tropical storm later that day. Aurora reached a peak of 50 mph winds before hitting eastern Oman on the 10th, where it dissipated shortly thereafter. It is unknown why it was named.

Tropical Storm Two (2B)

Tropical Storm Two, which began its life on October 1 in the central Bay of Bengal, hit northeastern India on the 3rd as a 60 mph tropical storm, dissipating the next day.

Tropical Depression Kim (16W)

The remnants of Western Pacific Tropical Storm Kim redeveloped in the northeastern Bay of Bengal near Myanmar. It paralleled the coastline, hit western Myanmar, and dissipated on the 20th.

Tropical Storm Three (3B)

65 mph Tropical Storm Three, which developed on November 5 in the central Bay of Bengal, hit southeastern Bangladesh on the 9th. The storm quickly dissipated without causing any reported damage.

1984 North Indian Ocean cyclone season

Tropical Storm One (1A)

On May 23 a tropical depression developed in the northwest Arabian Sea. It drifted west-northwestward, slowly organizing into a tropical storm on the 26th. It tracked westward through the Gulf of Aden, reaching a peak of 50 mph winds before hitting northern Somalia on the 28th. It quickly dissipated, after becoming the only North Indian tropical cyclone in recorded history to transit the Gulf of Aden.

Tropical Storm Two (2B)

Tropical Storm Two, which developed on October 10 in the central Bay of Bengal, hit northeastern India on the 14th, causing little damage or deaths.

Cyclone Three (3B)

Tropical Depression Three formed in the south-central Bay of Bengal. It tracked west-northwestward, becoming a tropical storm on the 10th and a cyclone on the 11th. A break in the ridge brought it northward, where steering currents collapsed on the 13th. After reaching a peak of 95 mph winds the cyclone looped slowly to the west and hit India on the 14th and dissipating on the 15th. Due to the stalling just offshore, the cyclone brought torrential flooding, resulting in at least 430 fatalities and moderate damage.

Cyclone Four (4B)

The final storm of the season began its life east of Sri Lanka on November 27. It drifted northwestward, becoming a tropical storm on the 28th before cyclonically looping to the west. On the 30th the storm became a cyclone, and hit southeastern India on the 1st as an 85 mph cyclone. It rapidly weakened over India, and lost its low level circulation on the 2nd. The mid-level circulation remained, and the system redeveloped over the Arabian Sea on the 3rd. After reaching a secondary peak of 70 mph winds the storm turned to the southwest, hit Somalia on the 7th, and dissipated on the 8th.
