Tropical Storm Norma (2005)
The 2005 Pacific hurricane season was a near-average season which produced fifteen named storms, only seven hurricanes formed and two major hurricanes. It was also the second consecutive season in which no tropical cyclone of at least tropical storm intensity made landfall. 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. Activity began with the formation of Hurricane Adrian, the fourth-earliest-forming tropical storm on record in the basin at the time. Adrian led to flash flooding and several landslides across Central America, resulting in five deaths and $12 million (2005 USD) in damage. Tropical storms Calvin and Dora caused minor damage along the coastline, while Tropical Storm Eugene led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Kenneth (2005)
Hurricane Kenneth was the strongest and longest-tracked hurricane of the 2005 Pacific hurricane season. The eleventh named storm and fifth hurricane of the season, Kenneth developed from a disturbance in the Intertropical Convergence Zone to the southwest of Mexico on September 14. It quickly attained peak winds of 135 mph (215 km/h) on September 18, before weakening due to increased wind shear and turning to a southwest drift. After weakening to tropical storm status, Kenneth attained a steady west-northwest motion and encountered favorable enough conditions for it to gain power and attain hurricane status on September 25. The cyclone again weakened as its motion halted, and on September 30 Kenneth dissipated a short distance off the Big Island of Hawaii. The remnants of Kenneth produced one of the highest rainfall totals in Hawaii, reaching up to 12 inches (305 mm) on Oahu. The rainfall caused flooding, though no major damage was reported.

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] |
Madden–Julian Oscillation
The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30- to 90-day) variability in the tropical atmosphere. It was discovered in 1971 by Roland Madden and Paul Julian of the American National Center for Atmospheric Research (NCAR). It is a large-scale coupling between atmospheric circulation and tropical deep atmospheric convection. Unlike a standing pattern like the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation is a traveling pattern that propagates eastward, at approximately , through the atmosphere above the warm parts of the Indian and Pacific oceans. This overall circulation pattern manifests itself most clearly as anomalous rainfall. The Madden–Julian oscillation is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian and Pacific Ocean. The anomalous rainfall is usually first evident over the western Indian Ocean, and remains evi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
1995 Pacific Hurricane Season
The 1995 Pacific hurricane season was the least active Pacific hurricane season since 1979, and marked the beginning of a multi-decade period of low activity in the basin. Of the eleven tropical cyclones that formed during the season, four affected land, with the most notable storm of the season being Hurricane Ismael, which killed at least 116 people in Mexico. The strongest hurricane in the season was Hurricane Juliette, which reached peak winds of 150 mph (240 km/h), but did not significantly affect land. Hurricane Adolph was an early-season Category 4 hurricane. Hurricane Henriette brushed the Baja California Peninsula in early September. The season officially started on May 15, 1995, in the Eastern Pacific, and on June 1, 1995, in the Central Pacific, and lasted until November 30, 1995. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The season saw eleven tropical cyclones form, ...

1989 Pacific Hurricane Season
The 1989 Pacific hurricane season was the first near normal season since 1981. The season officially started on May 15, 1989, in the eastern Pacific, and June 1, 1989, in the central Pacific, and lasted until November 30, 1989. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. A total of 18 storms and 9 hurricanes formed, which was near long-term averages. Four hurricanes reached major hurricane status (Category 3 or higher) on the Saffir–Simpson scale. Land impacting storms include Hurricanes Cosme, Kiko, and Raymond. Cosme crossed over Mexico and killed 30 people. Hurricane Kiko made landfall on the Gulf of California side of the Baja California Peninsula as a major hurricane. Hurricane Raymond was the strongest storm of the season, but weakened significantly before landfall. __TOC__ Seasonal summary ImageSize = width:800 height:215 PlotArea = top:10 bottom:80 right:20 left:20 Legend = ...

1971 Pacific Hurricane Season
The 1971 Pacific hurricane season began on May 15, 1971, in the east Pacific, and on June 1, 1971, in the central Pacific. It ended on November 30, 1971. These dates conventionally delimit the period of time when tropical cyclones form in the east Pacific Ocean. The 1971 season was above average with 18 named storms. Twelve hurricanes formed, of which six became major hurricanes by reaching Category 3 or higher on the Saffir-Simpson Hurricane Scale. At the time, this was a record number of storms. This season had six landfalls (Agatha, Bridget, Katrina, Lily, Olivia and Priscilla), the highest number of landfalling Pacific tropical cyclones in one season. __TOC__ Systems ImageSize = width:800 height:205 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/05/1971 till:12/12/1971 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/0 ...

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 ...

2005 Pacific Hurricane Season Three Active Storms
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a one-minute interval 10 m above th ...

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as ''El Niño'' and the cooling phase as ''La Niña''. The ''Southern Oscillation'' is the accompanying atmospheric component, coupled with the sea temperature change: ''El Niño'' is accompanied by high air surface pressure in the tropical western Pacific and ''La Niña'' with low air surface pressure there. The two periods last several months each and typically occur every few years with varying intensity per period. The two phases relate to the Walker circulation, which was discovered by Gilbert Walker during the early twentieth century. The Walker circulation is caused by the pressure gradient force that results from a high-pressure area over the eastern Pacific Ocean, and a low-pressure system over Indonesia. Weak ...
