Hurricane Roslyn (1992)
The 1992 Pacific hurricane season is the most active Pacific hurricane season on record, featuring 27 named storms, and the second-costliest Pacific hurricane season in history, behind the 2013 season. The season also produced the second-highest ACE value on record in the basin, only surpassed by the 2018 season. The season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, these bounds were easily exceeded when Hurricane Ekeka formed on January 28 and again a couple months later with Tropical Storm Hali. The most notable storm was Hurricane Iniki, which caused billions of dollars of damage to the Hawaiian Islands, primarily in Kauai, along with six casualties. Hurricanes Lester, Virgil, Winifred, and Orlene also made landfall and killed several people, but were significantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Tina (1992)
Hurricane Tina was the strongest and longest-lived storm of the 1992 Pacific hurricane season, which also threatened land for a brief period. The twenty-fourth tropical cyclone, twenty-second tropical storm, fourteenth hurricane, and eighth major hurricane of the record breaking season, Tina formed from a tropical wave on September 17. The storm moved towards the west and strengthened into a hurricane. A breakdown in a ridge and to the north and a trough then re-curved Tina to the northeast and towards land, still moving slowly and gradually slowing down. The trough broke down and was replaced by a strong ridge. Tina then changed direction again and headed out to sea. It intensified into a Category 4 storm with winds of 150 mph (240 km/h) and a central pressure of 932 millibars. Tina then slowly weakened as it turned to the north. Tropical Depression Tina dissipated on October 11, shortly after entering the Central Pacific Hurricane Center's area of responsibili ...

Hurricane Virgil (1992)
Hurricane Virgil was a late season hurricane of the 1992 Pacific hurricane season that struck southwestern Mexico in October 1992. Forming from a tropical wave that left Africa on September 13, it slowly developed into a tropical depression. It soon strengthened into Tropical Storm Virgil, and rapidly intensified into a hurricane on October 2. Continuing to intensify, the hurricane attained major hurricane strength, and peaked as a Category 4 hurricane off the coast of Mexico. Shortly before landfall, it weakened to a Category 2 hurricane, and it dissipated on October 5. Damage was generally minimal, though one person was reported missing. Meteorological history Virgil originated from a tropical wave that moved off the coast of Africa on September 13, 1992, beginning a westward course through the Atlantic and Caribbean without much development, although there was an increase convection near the Lesser Antilles on the September 20. However, this was disorganized and suppressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical cyclone development. There is a limit on tropical cyclone i ...

140th Meridian West
The meridian 140° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole. The line is the divider in the area of warning responsibility between the National Hurricane Center and the Central Pacific Hurricane Center in the north Pacific Ocean. The 140th meridian west forms a great circle with the 40th meridian east.

Tropical Cyclone
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 ...

Central Pacific Hurricane Center
The Central Pacific Hurricane Center (CPHC) of the United States National Weather Service is the official body responsible for tracking and issuing tropical cyclone warnings, watches, advisories, discussions, and statements for the Central Pacific region: from the equator northward, 140°W–180°W, most significantly for Hawai‘i. It is the Regional Specialized Meteorological Center (RSMC) for tropical cyclones in this region, and in this capacity is known as RSMC Honolulu. Based in Honolulu, Hawaii, the CPHC is co-located with the National Weather Service's Honolulu forecast office on the campus of the University of Hawaii at Mānoa. The Honolulu forecast office activates the CPHC when tropical cyclones form in, or move into, the Central Pacific region. The CPHC replaced the previous forecaster, the Joint Hurricane Warning Center, starting in the 1970 season. Area of responsibility The CPHC's area of responsibility is the Central Pacific (CP) region, which is an administra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Niño
El Niño (; ; ) is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (approximately between the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to last close to four years; however, records demonstrate that the cycles have lasted between two and seven years. During the development of El Niño, rainfall develops between September–November. The cool phase of ENSO is es, La Niña, translation=The Girl, with SSTs in the eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used by various agencies to express the energy released by a tropical cyclone during its lifetime. It is calculating by summing the square of a tropical cyclone's maximum sustained winds, measured every six hours. The resulting total can be divided by 10,000 to make it more manageable, or added to other totals in order to work out a total for a particular group of storms. The calculation was originally created by William Gray and his associates at Colorado State University as the Hurricane Destruction Potential index, which took the square of each hurricane's maximum sustained winds above every six hours. This index was adjusted by the United States National Oceanic and Atmospheric Administration in 2000 to include all tropical cyclones, with winds above and renamed accumulated cyclone energy. The index has since been used by various other agencies to calculate a storm's accumulated cyclone energy, including the Australian Bureau of ...

Tropical Storm Zeke (1992)
Tropical Storm Zeke was the final named storm of the record-breaking 1992 Pacific hurricane season. Forming out of a tropical wave on October 25, Zeke began as a disorganized depression. Tracking west-northwestward, the system gradually developed organized convection and intensified into a tropical storm. However, it soon entered a high wind shear environment, causing Zeke to weaken to a tropical depression. The following day, the storm re-intensified despite unfavorable conditions and later attained peak winds of 50 mph (85 km/h) on October 29. Rapid weakening followed shortly thereafter as convection dissipated and the center became exposed. During the afternoon of October 30, Zeke degenerated into a remnant low pressure system and dissipated several days later several hundred miles south of Baja California Sur. On October 29, tropical storm watches and warnings were issued for portions of the Mexican coastline; however, these were canceled the foll ...

Hurricane Winifred
Hurricane Winifred was the last tropical cyclone to make landfall in the record-breaking 1992 Pacific hurricane season. Impacting western Mexico, especially Colima and Michoacán, Hurricane Winifred brought heavy rain and destruction to the area. Rains flooded farms and roads, and caused more than $5 million (1992 USD, $ USD) in damage and a total of three people were killed. The last major hurricane, and hurricane of its season, Winifred existed in October 1992. It formed southeast of Acapulco on October 6 as the twenty-fourth east Pacific tropical cyclone of its season, and recurved as it strengthened. It peaked as a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. It made landfall southeast of Manzanillo, Colima and dissipated inland. Meteorological history On October 1, a disorganized area of thunderstorms existed south of Panama. It gradually headed west-northwestward, slowly organized, and developed deep and concentrated convection. The disturbed area had ...

Tropical Storm Agatha (1992)
Tropical Storm Agatha was the deadliest tropical cyclone to form during the 1992 Pacific hurricane season, killing 10 people as it passed offshore Mexico. The third named storm of the record-breaking season, Agatha developed as a tropical depression off the Pacific coast of Mexico on June 1. The storm gradually organized over the next several hours. As it moved northward, the depression intensified into Tropical Storm Agatha later that day. After reaching its peak winds as a strong tropical storm, Agatha steadily weakened while turning to the west. The system was downgraded to a tropical depression on June 5, and subsequently lost its tropical characteristics the next day. Although Agatha never made landfall, the storm's outer rainbands triggered widespread flooding that killed ten people. Meteorological history On May 26, a tropical wave—or a quasi-equatorward area of low pressure—moved off the Central American coast into the east Pacific. Over the subsequent days t ...
