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] |
Hurricane Celia (2010)
Hurricane Celia was the second-earliest forming Category 5 hurricane in the Eastern Pacific on record, after 1973's Hurricane Ava. The fourth tropical cyclone, third named storm, first hurricane, and first major hurricane of the very inactive 2010 Pacific hurricane season, Celia formed from a tropical wave about southeast of Acapulco, Mexico on June 18, Celia quickly organized as deep convection consolidated around the center, attaining hurricane status by June 20. Over the following days, the hurricane's winds fluctuated as wind shear impeded significant development hindering it from becoming potentially dangerous. Once this shear lightened on June 24, the storm rapidly intensified to attain its peak strength with winds of and an estimated barometric pressure of 921 mbar (hPa; ). Not long after reaching this strength, wind shear increased and the system entered a dry, stable environment. Over the following 42 hours, Hurricane Celia's sustained winds decreased ...

1990 Pacific Hurricane Season
The 1990 Pacific hurricane season was a very active season which observed 21 named storms within the basin. The season also produced the fourth highest ACE index value on record. The season was 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, the formation of tropical cyclones is possible at any time of the year, as illustrated in 1990 by the formation of the season's first named storm, Hurricane Alma, on May 12. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific Overall, the impact of this season was minimal. Tropical Storm Rachel made two landfalls in Mexico and brought rain to the United States. Hurricane Boris brought light showers to California. Seasonal summary The 1990 eastern North Pacific hurricane season was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Storm Georgette (2010)
Tropical Storm Georgette was a short-lived tropical storm that struck Baja California Sur in September 2010. Georgette originated from an area of disturbed weather over the eastern Pacific ocean on September 20. The next day, the system was upgraded into a tropical storm a short distance south of Baja California Sur. As the storm moved over the peninsula, it weakened to a tropical depression. It continued north and as such made landfall on mainland Mexico on September 22. Georgette dissipated early the next day while located inland over Sonora. Although officials noted the threat for heavy rainfall across northwest Mexico and Baja California, damage was minimal and no deaths were reported in the country. However, remnant moisture moved into New Mexico, producing flooding that killed one person. Meteorological history The origins of Tropical Storm Georgette were from a tropical wave that moved off the west coast of Africa on September 1. Lacking organization, the w ...

Hurricane Frank (2010)
Hurricane Frank was a Category 1 hurricane that caused minor damage in Mexico in late August 2010. The ninth tropical cyclone, sixth named storm, and third (and final) hurricane of the inactive 2010 Pacific hurricane season, Frank formed from an area of thunderstorms from the Caribbean Sea, and became Tropical Depression Nine-E on August 21 while located just south of the Mexican Coast. It moved northwest, and became Tropical Storm Frank only 12 hours after it was declared a depression. It strengthened to its initial peak as a moderate tropical storm, and weakened due to increasing wind shear late on the August 23. It later recovered, and became a hurricane on August 25. After peaking as a strong Category 1 hurricane, it rapidly weakened, and dissipated on August 28. Although Frank never made landfall, it did impact western Mexico. A total of six people were killed with over 800,000 people affected. Meteorological history Frank originated from a difficult to track tropical wave t ...

Tropical Storm Agatha
Tropical Storm Agatha was a weak but deadly tropical cyclone that brought widespread floods to much of Central America, and was the deadliest tropical cyclone in the eastern Pacific since Hurricane Pauline in 1997. The first storm of the 2010 Pacific hurricane season, Agatha originated from the Intertropical Convergence Zone, a region of thunderstorms across the tropics. It developed into a tropical depression on May 29 and tropical storm later, it was dissipated on May 30, reaching top winds of 45 mph ( and a lowest pressure of 1000 mbar (hPa; 29.53 inHg). It made landfall near the Guatemala–Mexico border on the evening of May 29. Agatha produced torrential rain all across Central America, which resulted in the death of one person in Nicaragua. In Guatemala, 152 people were killed and 100 left missing by landslides. Thirteen deaths also occurred in El Salvador. Agatha soon dissipated over Guatemala. As of June 15, officials in Guatemala have stated that 165 people were kil ... [...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, ...

Tropical Cyclone Naming
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific; while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government Meteorologist Clement Wragge, who named systems between 18 ...

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] |
Hurricane Felicia (2009)
Hurricane Felicia was the third strongest tropical cyclone of the 2009 Pacific hurricane season, as well as the strongest storm to exist in the eastern Pacific at the time since Hurricane Daniel in 2006. Forming as a tropical depression on August 3, the storm supported strong thunderstorm activity and quickly organized. It became a tropical storm over the following day, and subsequently underwent rapid deepening to attain hurricane status. Later that afternoon, Felicia developed a well-defined eye as its winds sharply rose to major hurricane-force on the Saffir–Simpson scale. Further strengthening ensued, and Felicia peaked in intensity as a Category 4 hurricane with sustained winds of and a barometric pressure of 935 mbar (hPa; ). After reaching this strength, unfavorable conditions, such as wind shear, began to impact the storm while it took on a northwestward path. Henceforth, Felicia slowly weakened for several days; by August 8 it had been downgraded to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Niña
La Niña (; ) is an oceanic and atmospheric phenomenon that is the colder counterpart of as part of the broader El Niño–Southern Oscillation (ENSO) climate pattern. The name ''La Niña'' originates from Spanish for "the girl", by analogy to ''El Niño'', meaning "the boy". In the past, it was also called an ''anti-El Niño'' and ''El Viejo'', meaning "the old man." During a La Niña period, the sea surface temperature across the eastern equatorial part of the central Pacific Ocean will be lower than normal by 3–5 °C (5.4–9 °F). An appearance of La Niña often persists for longer than five months. El Niño and La Niña can be indicators of weather changes across the globe. Atlantic and Pacific hurricanes can have different characteristics due to lower or higher wind shear and cooler or warmer sea surface temperatures.

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 ...
