1984–85 South-West Indian Ocean Cyclone Season
The 1984–85 South-West Indian Ocean cyclone season was an average cyclone season. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion. The first storm formed in mid-November, though it was not officially named. A few days later, the first official storm of the year (Anety) formed. In December, one storm formed. During January 1985, two tropical cyclones formed towards the end of the month. Three more systems developed in a short period of time in early to mid-February. After nearly two more months of inactivity, an unusually powerful late season storm developed (Helisaonina) in mid-April, which was the strongest storm of the year. While a number of storms during the season reached severe tropical storm status, only one of those intensified further. Even though two tropical cyclones this year made landfall, no known damage was recorded. Seasonal summary During the season, advisories were issued by Météo-France's (MFR ...

1982–83 South-West Indian Ocean Cyclone Season
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. Th ...

Hurricane
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

1985 North Indian Ocean Cyclone Season
The 1985 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. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD. Systems Tropical Storm One (1B) Tropical Storm One, which developed in the central Bay of Bengal on May 22, strengthened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1985 Pacific Typhoon Season
The 1985 Pacific typhoon season has no official bounds; it ran year-round in 1985, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. A total of 29 tropical depressions formed this year in the Western Pacific, of which 28 became tropical storms. 17 storms reached typhoon intensity, of which one typhoon reached super typhoon strength. The strongest cyclone of the season, Dot, reached category 5 on the Saffir–Simpson scale to the east of the Phili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1985 Pacific Hurricane Season
The 1985 Pacific hurricane season is the third-most active Pacific hurricane season on record. It officially started on May 15, 1985, in the eastern Pacific, and on June 1, 1985, in the central Pacific, and lasted until November 30, 1985. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. At the time, the 1985 season was the most active on record in the eastern north Pacific, with 28 tropical cyclones forming. Of those, 24 were named, 13 reached hurricane intensity, and 8 became major hurricanes by attaining Category 3 status or higher on the Saffir–Simpson scale. At that time, the 24 named storms was a record; however, this record was broken seven years later in 1992, and was therefore recognized as the second busiest season within the basin, until it was surpassed exactly thirty years later by the 2015 season. Despite the activity, only one system made landfall in 1985. Hurricane Waldo caused mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1984 Pacific Hurricane Season
The 1984 Pacific hurricane season featured numerous tropical cyclones, several of which were impactful to land. It was a busy hurricane season with 21 named storms, 13 hurricanes, and 7 major hurricanes, the latter of which are Category 3 or stronger cyclones on the Saffir–Simpson scale. This activity was unusual given the presence of a La Niña, which typically suppresses Central and East Pacific tropical cyclone activity, and only average sea surface temperatures. Seasonal activity began on May 17 and ended on November 8. This lies within the confines of a traditional hurricane season which begins on May 15 in the East Pacific and June 1 in the Central Pacific, and ends on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form. The drought-stricken Hawaiian Islands received beneficial rainfall from Hurricane Douglas in July and Tropical Storm Kenna in August. The remnants of hurr ...

1985 Atlantic Hurricane Season
The 1985 Atlantic hurricane season had six United States landfalling hurricanes, tied with 1886 and 2020 for the highest number on record. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 ...

1984 Atlantic Hurricane Season
The 1984 Atlantic hurricane season was the most active since 1971, though the season was below average in hurricanes and major hurricanes. It officially began on June 1, 1984, and lasted until November 30, 1984. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The 1984 season was an active one in terms of named storms, but most of them were weak and stayed at sea. Most of the cyclones tracked through the northwest subtropical Atlantic west of the 50th meridian to near the Eastern coast of the United States between mid-August and early October. The most damaging storm was Hurricane Klaus, which caused $152 million (1984 dollars) in damage in Puerto Rico. Hurricane Diana was the first hurricane to strike a nuclear power plant without incident; it was also the first major hurricane to strike the U.S. East Coast in nearly 20 years. Also of note was Hurricane Lili, which lasted well after the official en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfall
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there. Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as friction with the ...
