1996 Pacific Hurricane Season
The 1996 Pacific hurricane season is tied with 2021 for the most Pacific hurricanes to make landfall on Mexico in one year, with four striking the country. It was a below average season that produced 9 tropical storms, 5 hurricanes and 2 major hurricanes. With 9 tropical storms, 1996 ranks as the second-least active Pacific hurricane season on record. It officially began May 15, 1996, in the eastern north Pacific and on June 1, 1996, in the central north Pacific. It ended on November 30, 1996. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The season slightly exceeded these bounds when tropical storm One-E formed on May 13. Although tropical cyclone formation was below average, the season was destructive. Twelve tropical cyclones formed during the season, of which five made landfall and two other impacted land areas. Two tropical cyclones that formed in other basins entered the eastern north Pacific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Cesar–Douglas
Hurricane Cesar–Douglas was one of the few tropical cyclones to survive the List of Atlantic–Pacific crossover hurricanes, crossover from the Atlantic to east Pacific basin, and was the last to receive two names upon doing so. Hurricane Cesar was the third named storm and second hurricane of the 1996 Atlantic hurricane season. The system formed in the southern Caribbean Sea and affected several countries in South America before crossing Nicaragua and entering the Eastern Pacific where it was renamed Hurricane Douglas, the fourth named storm, third hurricane, and first and strongest major hurricane of the 1996 Pacific hurricane season. The storm killed 113 people in Central America, Central and South America and left 29 others missing, mainly due to flooding and mudslides. Meteorological history The origins of Hurricane Cesar were from a tropical wave and an elongated area of low pressure area, low pressure that emerged into the Atlantic from the west coast of Africa ...

Hurricane Dolly (1996)
Hurricane Dolly caused flooding throughout Mexico in August 1996. The fourth named storm and third hurricane of the season, Dolly developed from a tropical wave to the west-southwest of Jamaica on August 19. Initially a tropical depression, the system strengthened into a tropical storm about twelve hours later. Dolly headed westward and intensified into a Category 1 hurricane late on August 20. It then made landfall near Chetumal, Quintana Roo. The system weakened to a tropical depression on August 21. Later that day or early on August 22, Dolly emerged into the Bay of Campeche and quickly re-strengthened into a tropical storm. The storm deepened further and was upgraded to a hurricane again by midday on August 23; Dolly simultaneously peaked with winds of 80 mph (130 km/h). Around that time, it struck between Tuxpan, Veracruz, and Tampico, Tamaulipas. Dolly quickly weakened to a tropical depression early on August 24, but remained ...

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] |
2007 Pacific Hurricane Season
The 2007 Pacific hurricane season was a below-average Pacific hurricane season, featuring one major hurricane. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the region. The first tropical cyclone of the season, Alvin, developed on May 27, while the final system of the year, Kiko, dissipated on October 23. Due to unusually strong wind shear, activity fell short of the long-term average, with a total of 11 named storms, 4 hurricanes, and 1 major hurricane. At the time, 2007 featured the second-lowest value of the Accumulated cyclone energy (ACE) index since reliable records began in 1971. Two tropical cyclones – Cosme and Flossie – crossed into the central Pacific basin during the year, activity below the average of 4 to 5 systems. Impact during the season was relatively minimal. In early J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2010 Pacific Hurricane Season
The 2010 Pacific hurricane season was the least active Pacific hurricane season since modern records, tied with 1977. The season saw only eight named storms, alongside a record-breaking low of three hurricanes. However, of those three, two of them became major hurricanes, and one hurricane, Celia, reached Category 5 intensity on the Saffir-Simpson scale. Also had the second-fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they 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. Unlike the previous season, the first storm of the season, Agatha, formed during the month of May. Agatha developed on May 29 near the coast of Guatemala. In the second week of June, a sudden spre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1977 Pacific Hurricane Season
The 1977 Pacific hurricane season stands alongside 2010 Pacific hurricane season, 2010 as the least active Pacific hurricane season since reliable records began in 1971 Pacific hurricane season, 1971. Only eight tropical storms formed throughout the year; four further intensified into hurricanes, yet none strengthened into major hurricanes—a Category 3 or stronger on the Saffir–Simpson scale—an occurrence not seen again until 2003 Pacific hurricane season, 2003. Most tropical cyclones remained over the open eastern Pacific; however, the remnants of hurricanes Hurricane Doreen (1977), Doreen and Hurricane Heather (1977), Heather led to heavy rainfall which damaged or destroyed structures and flooded roadways throughout the Southwest United States. Notably, Hurricane Anita which originally formed in the Gulf of Mexico made the rare trek across Mexico into the eastern Pacific, briefly existing as a tropical depression. Eight deaths were recorded while damage reached $39.6 m ... [...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 ...

International Dateline
The International Date Line (IDL) is an internationally accepted demarcation on the surface of Earth, running between the South and North Poles and serving as the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for every 15° of longitude crossed, and *Back by 24 hours upon crossing the International Date Line. Failing to do this would make their time inaccurate to the local time. The Arab geographer Abulfed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended for the protection of primarily military ships and aircraft as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1979 Pacific Hurricane Season
The 1979 Pacific hurricane season was an inactive season, featuring 10 named storms, 6 hurricanes, and 4 major hurricanes. It featured zero tropical cyclones in the Central Pacific, the most recent occurrence on record as of 2021. An average year sees four to five tropical cyclones in that basin. Seasonal activity in 1979 remained within the confines of a traditional hurricane season, which begins on May 15 and ends on November 30 in the East Pacific basin. Those dates conventionally delimit the period during each year when most tropical cyclones occur. The season's first system, Andres, developed on May 31, while the year's final cyclone, Jimena, dissipated on November 18. In early June, Andres moved onshore Mexico as a minimal hurricane, while in late October, Ignacio struck the coastline as a tropical depression. Impacts from those storms were minimal, as were the effects of the preponderance of systems during the season. No casualties or damage were reporte ...
