1996 Pacific Hurricane Season
The 1996 Pacific hurricane season had below normal tropical cyclone activity, producing 9 tropical storms, of which 5 became hurricanes, with 2 of those intensifying into major hurricanes. With an Accumulated cyclone energy (ACE) index of 53.9, the season ranks among the least intense Pacific hurricane seasons 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. Much of the season's activity was clustered near the coast of Southwest Mexico, with four hurricanes and one tropical storm making landfall along it. The most impactful were: Hurricane Alma, which was responsible for 20 deaths, and Hurricane Fausto, which left behind damage amounting to around $800,000 (1996 ...

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 remain ...

2010 Pacific Hurricane Season
The 2010 Pacific hurricane season was the least active Pacific hurricane season on record (reliable records began in 1971), tied with 1977 and 1996 season.The season accumulated the second-fewest ACE units on record, as many of the tropical cyclones were weak and short-lived. Altogether, only three of the season's eight named storms strengthened into hurricanes. Of those, two became major hurricanes, with one, Celia, reaching Category 5 intensity on the Saffir-Simpson scale. Despite the inactivity, however, it was the costliest Pacific hurricane season on record at the time, mostly due to Tropical Storm Agatha. The season officially began on May 15 in the eastern North Pacific (east 140°W) and on June 1 in the central North Pacific (from 140°W to the International Date Line). It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of t ...

1977 Pacific Hurricane Season
The 1977 Pacific hurricane season stands alongside 2010 as the least active Pacific hurricane season since reliable records began in 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. Most tropical cyclones remained over the open eastern Pacific; however, the remnants of hurricanes Doreen and 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 million (1977 USD). __TOC__ Seasonal summary The 1977 Pacific hurricane season was an inactive season, with the first cyclone forming ...

Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. The ACE index may refer to a single storm or to groups of storms such as those within a particular month, a full season or combined seasons. It is calculated by summing the square of tropical cyclones' maximum sustained winds, as recorded every six hours, but only for windspeeds of at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph); the resulting figure is divided by 10,000 to place it on a more manageable scale. The calculation originated as the Hurricane Destruction Potential (HDP) index, which sums the squares of tropical cyclones' maximum sustained winds while at hurricane strength, at least 64 knots (≥ 119 km/h; 74 mph) at six-hour recorded intervals across an entire season. The HDP index was later modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Dateline
The International Date Line (IDL) is the line extending between the South Pole, South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180th meridian, 180.0° 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. The line is a Cartography, cartographic convention and is not defined by international law. This has made it difficult for cartographers to agree on its precise course and has allowed countries through whose waters it passes to move it at times for their convenience. Geography Circumnavigating the globe People traveling westward circumnavigation, 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.

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 primarily for the protection of U.S. 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 adminis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1979 Pacific Hurricane Season
The 1979 Pacific hurricane season was an inactive North Pacific hurricane season, featuring 10 named storms, 6 hurricanes, and 4 major hurricanes. All tropical cyclone activity this season was confined to the Eastern Pacific, east of 140°W. For the first time since 1977, no tropical cyclones formed in, or entered into the Central Pacific, between 140°W and the International Date Line. The season officially started on May 15, 1979 in the Eastern Pacific and on June 1 in the Central Pacific; they both ended on November 30, 1979. These dates conventionally delimit the period of each year when most tropical cyclones form in these basins. The season's first storm, Andres, developed on May 31, while its last, 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 prep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. From Pole to Pole Starting at the North Pole and heading south to the South Pole The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface.

Atlantic Hurricane
An Atlantic hurricane is a type of tropical cyclone that forms in the Atlantic Ocean primarily between June and November. The terms "hurricane", "typhoon", and "cyclone, tropical cyclone" can be used interchangeably to describe this weather phenomenon. These storms are continuously rotating around a low pressure center, which causes stormy weather across a large area, which is not limited to just the eye of the storm. They are organized systems of clouds and thunderstorms that originate over tropical or subtropical waters and have closed low-level circulation, and should not be confused with tornadoes, which are another type of cyclone. In the North Atlantic and the Eastern Pacific, the term hurricane is used, whereas ''typhoon'' is used in the Western Pacific near Asia. The more general term ''cyclone'' is used in the rest of the ocean basins, namely the South Pacific and Indian Ocean. Tropical cyclones can be categorized by intensity. ''Tropical storms'' have one-minute maxi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
