The 1990–91 South-West Indian Ocean cyclone season was fairly quiet, although activity began early and the final named storm formed at a record late date. There were seven named storms classified by the Météo-France office (MFR) on Réunion, as well as three depressions; an additional depression was classified by the Joint Typhoon Warning Center (JTWC), an unofficial warning agency. The JTWC tracked storms in both September and October, although neither affected land. In late November, another short-lived depression formed in the northeastern portion of the basin. Activity remained minimal until January, when Tropical Storm Alison formed in the eastern portion of the basin. Later in the month, Cyclone Bella became the strongest storm of the season, reaching 10‑minute maximum sustained winds of 155 km/h (100 mph). It passed near the island of Rodrigues, becoming the worst cyclone there in 20 years and killing half of the population of one endangered species. Bella also likely caused a cargo ship to go missing with 36 people on board.Three storms developed in short succession in the second half of February. Cyclone Cynthia developed rapidly in the Mozambique Channel on February 16 and struck western Madagascar, killing 36 people and ruining local rice harvests. A residual trough after Cynthia dissipated spawned Tropical Storm Debra, which looped in the Mozambique Channel. Toward the end of the month, Tropical Storm Elma exited the basin into the adjacent Australian region, only to re-enter the south-west Indian Ocean and dissipate. Long-lived Cyclone Fatima originated in the Australian basin in late March and changed directions before becoming extratropical. On April 2, a tropical depression struck eastern Madagascar, killing 18 people. The final storm, Gritelle, was named on June 10, the latest on record.
The 1991–92 South-West Indian Ocean cyclone season was an average cyclone season in which most storms remained over open waters. At the time, the season's official bounds lasted from November 15, 1991, to April 30, 1992, although this season began early when three tropical depressions formed before the official start. The second, designated Tropical Depression A2 by the Météo-France office (MFR) on Réunion, passed north of Madagascar on October 16 before weakening.
The 1992–93 South-West Indian Ocean cyclone season lasted longer than normal, with the first storm Aviona forming on September 27 and the final storm Konita not dissipating until May 7. It was an above-average season, with four tropical cyclones – the equivalent of a minimal hurricane – along with six tropical storms, one subtropical depression, and several depressions including one that was named. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion (MFR), as well as by the Joint Typhoon Warning Center (JTWC).
The 1982–83 South-West Indian Ocean cyclone season was the least active cyclone season in the basin since 1961–1962. There were six systems that were named, although three of them – Arilisy, Clera, and Fely – failed to intensify beyond tropical depression status. No storms reached tropical cyclone status, according to the official warning agency for the basin, Météo-France, although the two strongest storms – Bemany and Elinah – peaked just below that intensity. The first named storm, Arilisy, formed on October 27, and dissipated without having affected land. However, the Joint Typhoon Warning Center (JTWC), which is an unofficial warning center for the basin, briefly tracked a tropical depression in July. The next storm was Bemany, which passed east of Mauritius near peak intensity in early December. Tropical Depression Clera existed briefly in the middle of September, and Tropical Storm Dadafy moved across the eastern portion of the basin in late December.
The 1989–90 South-West Indian Ocean cyclone season was an average cyclone season, with nine named storms and five tropical cyclones – a storm attaining maximum sustained winds of at least 120 km/h (75 mph). The season officially ran from November 1, 1989, to April 30, 1990. Storms were officially tracked by the Météo-France office (MFR) on Réunion while the Joint Typhoon Warning Center (JTWC) in an unofficial basis. The first storm, Cyclone Alibera, was the second longest-lasting tropical cyclone on record in the basin, with a duration of 22 days. Alibera meandered and changed directions several times before striking southeastern Madagascar on January 1, 1989, where it was considered the worst storm since 1925. The cyclone killed 46 people and left widespread damage. Only the final storm of the year – Severe Tropical Storm Ikonjo – also had significant impact on land, when it left $1.5 million in damage (1990 USD) in the Seychelles.
The 1986–87 South-West Indian Ocean cyclone season was below average due to an ongoing El Niño and a weak monsoon that suppressed convection and storms. There were only five named storms tracked by the Météo-France office (MFR) on Réunion. The United States-based Joint Typhoon Warning Center (JTWC) followed four other storms in the basin, which is the waters of the Indian Ocean south of the equator and west of 90° E to the coast of Africa. The JTWC tracked a storm on August 1 in the northeastern portion of the basin, unusual for the time of year. The first named storm was Severe Tropical Storm Alinina, which originated from the Intertropical Convergence Zone east of Madagascar in the middle of January. However, there was an unnamed tropical depression that produced heavy rainfall in Réunion and Madagascar, causing two deaths in the latter country.
The 1961–62 South-West Indian Ocean cyclone season was a busy cyclone season, lasting from December to April.
The 1940 Pacific typhoon season marked an interruption in meteorological records in both the Philippines and Hong Kong due to the start of World War II. There were 43 reported tropical cyclones, including 27 that attained typhoon status. The first storm was observed in February, and the first typhoon formed two months later, killing three people along Mindanao. Several storms formed in June and July, including reports of a typhoon in the newspapers that killed 52 in South Korea, and another typhoon reported in newspapers that killed one person on Samar after dropping heavy rainfall. The strongest typhoon of the season originated in July and attained a minimum pressure of 927 mbar (27.4 inHg), as reported by a ship northeast of the Philippines.
In 1900, 23 tropical cyclones were observed in the western Pacific Ocean, north of the equator and west of the International Date Line. In that region of the world, cyclones that attain maximum sustained winds of at least 118 km/h (74 mph) are known as typhoons. Of the 23 storms, 13 were tracked by the Hong Kong Observatory. Activity occurred from January to December, although the majority of the storms formed from June to November.
In 1901, 21 tropical cyclones were observed in the western Pacific Ocean, north of the equator. In that region of the world, cyclones that attain maximum sustained winds of at least 118 km/h (74 mph) are known as typhoons. Out of the 21 storms, the Hong Kong Observatory tracked nine of them. The strongest storm, known as the De Witte typhoon, reached a minimum barometric pressure of 920 mbar (27 inHg), before striking eastern China.
The 1942 Pacific typhoon season has no official bounds; it ran year-round in 1942, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1942 Pacific hurricane season.
The 1943 Pacific typhoon season has no official bounds; it ran year-round in 1943, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1943 Pacific hurricane season.
The 1944 Pacific typhoon season has no official bounds; it ran year-round in 1944, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1944 Pacific hurricane season.
There were 30 tropical cyclones in the western Pacific Ocean in 1931, including 19 typhoons, as well as one that developed in December of the previous year. The most significant typhoon was one that struck eastern China near Shanghai in the midst of the country's worst floods on record; heavy rainfall caused levees to collapse along the Grand Canal, killing an estimated 300,000 people, including about 2,000 people overnight in the city of Gaoyou.
The following is a list of Pacific typhoon seasons from 1920 to 1937. Data from these years was extremely unreliable, so there were many more typhoons that did not hit land and were not detected by ships. The average from these times was 23 tropical storms, which now would be considered a well-below-average season.
The following is a list of North Indian Ocean tropical cyclones from 1930 to 1939. Records from before the 1970s were extremely unreliable, and storms that stayed at sea were often only reported by ship reports.

The following is a list of weather events that occurred on Earth in the year 2002. There were several natural disasters around the world from various types of weather, including blizzards, cold waves, droughts, heat waves, tornadoes, and tropical cyclones. The deadliest disaster was a heat wave in India in May, which killed more than 1,030 people. The costliest event of the year was a flood in Europe in August, which killed 232 people and caused €27.7 billion (US$27.115 billion) in damage. In September, Typhoon Rusa struck South Korea, killing at least 213 people and causing at least ₩5.148 trillion (US$4.2 billion) in damage.
