North Indian Ocean tropical cyclone seasons
1979, 1980, 1981, 1982, 1983

The 1981 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea 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. [1] Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD. [2]

Systems

There were 12 depressions that developed during the season. The first formed on June 20 in the northern Bay of Bengal. It soon moved ashore and dissipated on June 24. In August, there were two depressions and a cyclonic storm in the Bay of Bengal. The first formed in the Bay of Bengal on August 3, which dissipated after moving ashore eastern India the next day. The other formed on August 12, moved ashore two days later, and dissipated on August 16. A land depression existed over eastern India on September 9. Another Bay of Bengal depression formed on September 17 and moved ashore India a day later. From October 31 to November 2, a depression existed in the central Bay of Bengal. A depression existed off southwest Myanmar from November 810. [3]

On August 7, a cyclonic storm formed in the northern Bay of Bengal. It moved ashore Odisha the next day, and progressed northwestward through India. It was last observed on August 10 over western India. [3]

A depression formed in the Bay of Bengal on September 24, and quickly intensified into a cyclonic storm while moving northwestward. On September 26, the storm moved ashore Odisha. It eventually turned northward, dissipating over Chhattisgarh on September 28. [3] Many huts were reported to be damaged due to gust winds over the coastal villages of Odisha.

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 according to the JTWC. Over the Arabian Sea, it turned northeastward where, after reaching a peak of 120 km/h (75 mph) winds, it hit western India on November 2 as it recurved northeastward. The IMD last reported the system on November 3. [3] Nearly 5700 huts were reported to be damaged due to gust winds over Gujarat at the time of landfall.

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 1300UTC of 10th as a 60 mph tropical storm. Widespread damage and flooding caused at least 200 fatalities and affected one million people.

The 2005 North Indian Ocean cyclone season caused much devastation and many deaths in Southern India despite the storms’ weakness. The basin covers the Indian Ocean north of the equator as well as inland areas, sub-divided by the Arabian Sea and the Bay of Bengal. Although the season began early with two systems in January, the bulk of activity was confined from September to December. The official India Meteorological Department tracked 12 depressions in the basin, and the unofficial Joint Typhoon Warning Center (JTWC) monitored two additional storms. Three systems intensified into a cyclonic storm, which have sustained winds of at least 63 km/h (39 mph), at which point the IMD named them.

<span class="mw-page-title-main">1992 North Indian Ocean cyclone season</span>

The 1992 North Indian Ocean cyclone season was unofficially the most active year on record for the basin, with 10 tropical storms developing, according to the Joint Typhoon Warning Center (JTWC). There are two main seas in the North Indian Ocean – the Bay of Bengal to the east of the Indian subcontinent – and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the JTWC releases unofficial advisories. An average of four to six storms 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.

<span class="mw-page-title-main">2003 North Indian Ocean cyclone season</span> North Indian Ocean tropical cyclone season

The 2003 North Indian Ocean cyclone season was the last season that tropical cyclones were not publicly labeled by India Meteorological Department (IMD). Also was mostly focused in the Bay of Bengal, where six of the seven depressions developed. The remaining system was a tropical cyclone that developed in the Arabian Sea in November, which was also the only system that did not affect land. There were three cyclonic storms, which was below the average of 4–6. Only one storm formed before the start of the monsoon season in June, although it was also the most notable. On May 10, a depression formed in the central Bay of Bengal, and within a few days became a very severe cyclonic storm. After it stalled, it drew moisture from the southwest to produce severe flooding across Sri Lanka, killing 254 people and becoming the worst floods there since 1947. Damage on the island totaled $135 million (2003 USD). The storm eventually made landfall in Myanmar on May 19. It is possible that the storm contributed to a deadly heat wave in India due to shifting air currents.
