2018 Pacific Hurricane Season
The 2018 Pacific hurricane season was one of the most active Pacific hurricane seasons on record, producing the highest accumulated cyclone energy value on record in the basin. The season had the fourth-highest number of named storms23, tied with 1982. The season also featured eight landfalls, six of which occurred in Mexico. The season officially began 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 basin. However, tropical cyclone formation is possible at any time of the year, as illustrated when the first tropical depression formed on May 10, five days prior to the official start of the season. The second named storm of the season, Hurricane Bud, struck Baja California Sur in mid-June, causing minor damage. Tropical Storm Carlotta stalled offshore of the Mexican coastline, where it also caused ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Walaka
Hurricane Walaka was a Category 5 hurricane that brought high surf and a powerful storm surge to the Hawaiian Islands. Walaka was the nineteenth named storm, twelfth hurricane, eighth major hurricane, and second Category 5 hurricane of the 2018 Pacific hurricane season. The tropical cyclone originated from an area of low pressure that formed around 1,600 mi (2,575 km) south-southeast of Hawaii on September 24. The system tracked westward and moved into the Central Pacific Basin about a day later. The disturbance continued westward over the next few days, organizing into a tropical depression on September 29. Later that day, the system strengthened into a tropical storm, receiving the name ''Walaka''. The storm then rapidly intensified, becoming a hurricane on September 30 and a major hurricane by October 1. The cyclone took on a more northward track under the influence of a low-pressure system located to the north. Walaka peaked as a Ca ...

Hurricane Harvey
Hurricane Harvey was a devastating Category 4 hurricane that made landfall on Texas and Louisiana in August 2017, causing catastrophic flooding and more than 100 deaths. It is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion (2017 USD) in damage, primarily from catastrophic rainfall-triggered flooding in the Houston metropolitan area and Southeast Texas; this made the storm the costliest natural disaster recorded in Texas at the time. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. In a four-day period, many areas received more than of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of , in Nederland, Texas, Harvey was the wettest tropical cyclone on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...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] |
Servicio Meteorológico Nacional (Mexico)
The Servicio Meteorológico Nacional (SMN) is Mexico's national weather organization. It collects data and issues forecasts, advisories, and warnings for the entire country. History A presidential decree founded El Observatorio Meteorológico y Astrónomico de México (The Meteorological and Astronomical Observatory of Mexico) on February 6, 1877 as part of the Geographic Exploring of the National Territory commission. By 1880, it became an independent agency located at Chapultepec Castle, then encompassing six observatories. In 1901, the Servicio Meteorologia Nacional was formed with 31 sections for each state and 18 independent observatories which reported back to the central office in Tacubaya via telegraph. It joined the World Meteorological Organization in 1947. By 1980, the organization included 72 observatories, of which eight launched weather balloons and radiosondes, and five radars serviced the country. In 1989, it became a subagency of the General de Administracion d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2002 Pacific Hurricane Season
The 2002 Pacific hurricane season was an above-average season which produced fifteen named storms. Eight hurricanes formed, including three Category 5 hurricanes, which tied for the most in a season with 1994 and 2018. Moreover, the season was a near-average season in terms of accumulated cyclone energy (ACE), with a total index of 125 units. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific and they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year. Tropical activity began with the formation of Tropical Storm Alma on May 24, before it became a major hurricane. The strongest hurricane of the season, Kenna, formed on October 22 and peaked as a Category 5 hurricane two days later. June was extremely quiet with no hurricanes formin ...

1994 Pacific Hurricane Season
The 1994 Pacific hurricane season was the final season of the eastern north Pacific's consecutive active hurricane seasons that started in 1982. The season officially started on May 15, 1994, in the eastern Pacific, and on June 1, 1994, in the central Pacific, and lasted until November 30, 1994. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone formed on June 18, while the last system dissipated on October 26. This season, twenty-two tropical cyclones formed in the north Pacific Ocean east of the dateline, with all but two becoming tropical storms or hurricanes. A total of 10 hurricanes occurred, including five major hurricanes. The above average activity in 1994 was attributed to the ongoing 1990–95 El Niño at the time. Of note in this season is an unusual spree of very intense storms; the season was the first on record to see three Category 5 hurricanes, later tied in ...

Hurricane Willa
Hurricane Willa was a powerful tropical cyclone that brought torrential rains and destructive winds to southwestern Mexico, particularly the states of Sinaloa and Nayarit, during late-October 2018. It was the twenty-fifth tropical cyclone, twenty-second named storm, thirteenth hurricane, tenth major hurricane, and record-tying third Category 5 hurricane of the 2018 Pacific hurricane season. Willa was the first major hurricane to make landfall in the Mexican state of Sinaloa since Lane in 2006. Willa originated from a tropical wave that the United States-based National Hurricane Center (NHC) began to monitor for tropical cyclogenesis in the southwestern Caribbean Sea on October 14. However, the system subsequently crossed over Central America into the East Pacific, without significant organization. The NHC continued to track the disturbance until it developed into a tropical depression on October 20, off the coast of southwestern Mexico. The depression strengthened into Tropi ...
