List Of Near-Equatorial Tropical Cyclones
Typically, tropical cyclones form at least 5.0 degrees of latitude north and south of the equator, or at least 300 nautical miles (556 km, 345 mi) of the equator. Despite the presence of sufficiently warm sea surface temperatures and generally low wind shear, tropical cyclogenesis is uncommon at these latitudes, due to a lack of the Coriolis force, which causes cyclones to spin. On rare occasions, tropical cyclones can develop within 5º of the equator, though it is more prevalent in the northwestern Pacific Ocean. Background Various factors converge to produce a tropical cyclone, including sufficiently warm sea surface temperatures, low wind shear, ample moisture, and enough atmospheric instability to produce thunderstorms. In addition, weather disturbances typically need to be far enough away from the equator to spin, known as vorticity. This is due to increasing Coriolis force closer to the poles, and which is zero at the equator. One associated phenom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vamei 2001-12-27 0123Z
Tropical Storm Vamei (also known as Typhoon Vamei) was a Pacific tropical cyclone that formed at about from the equator—closer than any other tropical cyclone on record. The last storm of the 2001 Pacific typhoon season, Vamei developed on 26 December at 1.4° N in the South China Sea. It strengthened quickly and made landfall along extreme southeastern Peninsular Malaysia. Vamei rapidly weakened into a remnant low over Sumatra on 28 December, and the remnants eventually re-organized in the North Indian Ocean. Afterward, the storm encountered strong wind shear once again, and dissipated on 1 January 2002. Though Vamei was officially designated as a tropical storm, its intensity is disputed; some agencies classify it as a typhoon, based on sustained winds of and the appearance of an eye. The storm brought flooding and landslides to eastern Peninsular Malaysia, causing $3.58 million in damage (2001 USD, $ USD) and five deaths. Meteorological history On 19 ...

Westerly Wind Burst
A westerly wind burst (WWB) or westerly wind event (WWE)https://glossary.ametsoc.org/wiki/Westerly_wind_burst is a phenomenon commonly associated with El Niño events, whereby the typical east-to-west trade winds across the equatorial Pacific shift to west-to-east. Definition A westerly wind burst is defined by Harrison and Vecchi (1997) as sustained winds of over a period of 5–20 days. However, no concrete definition has been determined, with Tziperman and Yu (2007) defining them as having winds of and lasting "at least a few days". On average, three of these events take place each year, but are significantly more common during El Niño years. They have been linked to various mesoscale phenomena, including tropical cyclones, mid-latitude cold surges, and the Madden–Julian oscillation. Their connection with Kelvin waves also indicate a connection with the onset of El Niño events, with every major occurrence since the 1950s featuring a westerly wind burst upon their ...

2003–04 South-West Indian Ocean Cyclone Season
The 2003–04 South-West Indian Ocean cyclone season featured the List of the most intense tropical cyclones#South-West Indian Ocean, most intense tropical cyclone in the South-West Indian Ocean, Cyclone Gafilo, as well as nine other tropical cyclone naming, named storms. Tropical activity began on September 28 when Moderate Tropical Storm Abaimba formed at a low latitude. Activity continued until late May, following Severe Tropical Storm Juba, which marked the third year in a row that a storm formed in May. The final disturbance, one of sixteen, dissipated on May 24. Activity was near average, and the season was one of the longest on record. The first tropical cyclone scales, intense tropical cyclone was Beni, which reached that intensity on November 13, the third-earliest on record. In December, Tropical Cyclone Cela moved across Madagascar, and Severe Tropical Storm Darius dropped heavy rainfall in the Mascarene Islands. In January, Cyclone Elita crossed Madagasc ...

1977 Pacific Typhoon Season
The 1977 Pacific typhoon season was one of the least active Pacific typhoon seasons on record, with only 21 tropical storms forming. It was also the second of three known typhoon seasons during the satellite era (since 1960) to not produce a Category 5-equivalent super typhoon, sandwiched between the 1974 and 2017 seasons. The season's first storm, Severe Tropical Storm Patsy, formed on March 23 and the last, Typhoon Mary, dissipated on January 2, 1978. With Mary spanning two calendar years, it became the fourth typhoon to do so since 1945. Since then, two other typhoons have achieved this feat. 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 1977 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressio ...

2015 Pacific Hurricane Season
The 2015 Pacific hurricane season is the second-most active Pacific hurricane season on record, with 26 named storms, only behind the 1992 Pacific hurricane season, 1992 season. A record-tying 16 of those storms became hurricanes, and a record 11 storms further intensified into major hurricanes throughout the season. The Central Pacific, the portion of the Northeast Pacific Ocean between the International Date Line and the 140th meridian west, had its most active year on record, with 16 tropical cyclones forming in or entering the basin. Moreover, the season was the third-most active season in terms of accumulated cyclone energy, amassing a total of 290 units. The season officially started on May 15 in the Eastern Pacific and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific hurricane, Northeast Pacific basin. However, the formation of ...

2023 Pacific Typhoon Season
The 2023 Pacific typhoon season was the fourth and final consecutive below-average season and became the third-most inactive typhoon season on record in terms of named storms, with just 17 named storms developing, only ahead of 2010 Pacific typhoon season, 2010 and 1998 Pacific typhoon season, 1998, however it had a slightly above average in terms of Accumulated Cyclone Energy, ACE. Despite the season occurring during an El Niño event, which typically favors activity in the basin, activity was abnormally low. This was primarily due to a consistent period of negative Pacific decadal oscillation, PDO, which typically discourages tropical storm formation in this basin. The season was less active than the 2023 Atlantic hurricane season in terms of named storms, the fourth such season on record, after 2005 Pacific typhoon season, 2005, 2010 Pacific typhoon season, 2010 and 2020 Pacific typhoon season, 2020. The season's number of storms also did not exceed that of the 2023 Pacific hur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 Pacific Typhoon Season
The 2014 Pacific typhoon season was a slightly below average season in terms of named storms, but featured the highest amount of Category 5 typhoons since 1997 Pacific typhoon season, 1997. This was mainly due to a developing El Niño that favors multiple powerful storms to form in the basin. The season formed twenty-three tropical storms (including one that crossed over from the Eastern/Central Pacific), eleven typhoons, eight super typhoons, and seven Category 5 typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically tropical cyclogenesis, develop between June and October. The season began with the development of Tropical Storm Lingling (2014), Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi (2014), Tropical Storm Jangmi which di ...

1979 Pacific Typhoon Season
The 1979 Pacific typhoon season featured the largest and most intense tropical cyclone recorded globally, Typhoon Tip. The season also used both male and female names as tropical cyclone names for the first time. Additionally, the season was slightly below-average in terms of tropical cyclone activity, with only 24 storms, 12 typhoons, and 4 super typhoons developing. The season had no official bounds; it ran year-round in 1979, 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 1979 Pacific hurricane season. Tropical storms formed in the entire west Pacific basin were assigned a name by the Joint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Alice (1979)
Typhoon Alice was an unusual and strong West Pacific tropical cyclone that caused extensive damage in the Marshall Islands in January 1979. The first tropical cyclone and the first typhoon of the 1979 Pacific typhoon season, Alice formed on , from a tropical disturbance at both an atypically low latitude near the equator and during a time of year climatologically unfavorable for tropical cyclogenesis. The system strengthened as it tracked northwest, reaching tropical storm strength on . Alice then began to move erratically through the Marshall Islands, causing heavy rainfall and gusty winds that destroyed crops throughout the archipelago. Significant damage occurred in Majuro and Enewetak Atoll, where gusts of were reported and one person was injured. Nuclear cleanup operations on Enewetak in the wake of postwar nuclear tests there were disrupted, with repair of cleanup facilities lasting several months. The damage toll was estimated at between US$50,000–$500,000. After J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1956 Pacific Typhoon Season
The 1956 Pacific typhoon season has no official bounds; it ran year-round in 1956, 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 1956 Pacific hurricane season. Tropical storms forming in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.

2004 North Indian Ocean Cyclone Season
The 2004 North Indian Ocean cyclone season was the first in which tropical cyclones were officially named in the basin. Cyclone Onil, which struck India and Pakistan, was named in late September. The final storm, Cyclone Agni, was also named, and crossed into the southern hemisphere shortly before dissipation. This storm became notable during its origins and became one of the storms closest to the equator. The season was fairly active, with ten depressions forming from May to November. The India Meteorological Department designated four of these as cyclonic storms, which have maximum sustained winds of at least averaged over three minutes. The Joint Typhoon Warning Center also issued warnings for five of the storms on an unofficial basis. In early May, two tropical storms formed in the basin The first formed on May 5 and meandered while intensifying, dropping in Aminidivi in the Lakshadweep group offshore western India, which was the highest daily rainfall total in t ...

2001 Pacific Typhoon Season
The 2001 Pacific typhoon season was an average season with twenty-six named storms, sixteen typhoons and three super typhoons, with a near normal Accumulated Cyclone Energy (ACE) of 307.3 units. It ran year-round in 2001, with most tropical cyclones in the northwestern Pacific Ocean tending between May and November. The early season was relatively inactive, with the first named storm, Cimaron, not developing until May 9. Taiwan suffered the most destruction from typhoons this year, with Typhoons Toraji, Nari, and Lekima being responsible for nearly 300 deaths in that island alone, making it one of the deadliest typhoon seasons in recorded history in that island. In November, Typhoon Lingling impacted the Philippines, killing 171 people, making it one of the deadliest Philippine storms this century. The season ended with the formation of Tropical Storm Vamei during the last week of December. Vamei would be notable for becoming the lowest latitude tropical storm, at 1.4°N, ...
