Tropical Cyclones In 2004
During 2004, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 132 systems formed with 82 of these developing further and were tropical cyclone naming, named by the responsible warning centre. The strongest tropical cyclone of the year was Cyclone Gafilo, which was estimated to have a minimum barometric pressure of . The most active basin in the year was the 2004 Pacific typhoon season, Western Pacific, which documented 29 named systems, while the 2004 Atlantic hurricane season, North Atlantic 15 named systems formed. Conversely, both the 2004 Pacific hurricane season, Eastern Pacific hurricane and 2004 North Indian Ocean cyclone season, North Indian Ocean cyclone seasons experienced a below average number of named systems, numbering 12 and 4, respectively. Activity across the southern hemisphere's three basins—South-West Indian Ocean tropical cyc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Low Ken (2004)
The tropics are the regions of Earth surrounding the equator, where the sun may shine Effect of Sun angle on climate, directly overhead. This contrasts with the temperate or Polar regions of Earth, polar regions of Earth, where the Sun can never be directly overhead. This is because of Axial tilt#Earth, Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics insolation, receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided Season#Tropical, by precipitation variations than by temperature variations. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South-West Indian Ocean Tropical Cyclone
In the south-west Indian Ocean, tropical cyclones form south of the equator and west of 90° E to the coast of Africa. Warnings and nomenclature In 1946, Réunion's first airstrip opened, then called Gillot, and now called Roland Garros Airport. In 1950, the first meteorological station on the island opened at the airport, operated by Météo-France (MFR). The agency began publishing annual reviews in the 1962–63 season. Each year, the Météo-France office (MFR) based on Réunion island issues warnings on tropical cyclones within the basin, which is defined as the waters of the Indian Ocean from the coast of Africa to 90° E, south of the equator. The agency issues the warnings as part of its role as a Regional Specialized Meteorological Center, designated as such in 1993 by the World Meteorological Organization. Intensities are estimated through the Dvorak technique, which utilizes images from satellites by the American National Oceanic and Atmospheric Admini ...

Cyclone Elita
Tropical Cyclone Elita was an unusual tropical cyclone that made landfall on Madagascar three times. The fifth named storm of the 2003–04 South-West Indian Ocean cyclone season, Elita developed in the Mozambique Channel on January 24, 2004. It strengthened to tropical cyclone status before striking northwestern Madagascar on January 28; it was the first storm to strike western Madagascar at that intensity since Cyclone Cynthia in 1991. Elita weakened to tropical depression status while crossing the island, and after exiting into the southwest Indian Ocean, it turned to the west and moved ashore in eastern Madagascar on January 31. After once again crossing the island, the cyclone reached the Mozambique Channel and re-intensified. Elita turned to the southeast to make its final landfall on February 3 along southwestern Madagascar. Two days later, it underwent an extratropical transition; subsequently, the remnant system moved erratically before dissipating on February 13. Elita ...

Cyclone Heta
Severe Tropical Cyclone Heta was a Category 5 tropical cyclone that caused moderate damage to the islands of Tonga, Niue, and American Samoa during late December 2003 and early January 2004. Heta formed on December 25, 2003; it reached a maximum intensity of and an estimated pressure of 915 hPa (27.02 inHg) before dissipating on January 11, 2004. It was the first named tropical cyclone to form during the 2003–04 South Pacific cyclone season. The damage Heta caused on Tonga, Niue, and American Samoa was estimated at $150 million (2004 USD), with most of the damage occurring in American Samoa; the cyclone was also responsible for one death. Heta precipitated a massive relief and clean-up operation that lasted throughout 2004. Meteorological history During December 25, 2003 the Fiji Meteorological Service reported that Tropical Disturbance 03F had developed underneath the subtropical ridge of high pressure about halfway between Fiji and Rotuma. At this time, the distu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Surface Temperatures
Sea surface temperature (or ocean surface temperature) is the ocean temperature, temperature of ocean water close to the surface. The exact meaning of ''surface'' varies in the literature and in practice. It is usually between and below the sea surface. Sea surface temperatures greatly modify air masses in the Atmosphere of Earth, Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. Warm sea surface temperatures can develop and Tropical cyclogenesis, strengthen cyclones over the ocean. Tropical cyclones can also cause a cool wake. This is due to turbulent mixing of the upper of the ocean. Sea surface temperature changes during the day. This is like the air above it, but to a lesser degree. There is less variation in sea surface temperature on breezy days than on calm days. Coastal sea surface temperatures can cause offshore winds to generate upwelling ...

Pacific Hurricane
A Pacific hurricane is a tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E), while the southern Pacific is divided into 2 sections, the Australian region (90°E to 160°E) and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variation in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of ENSO is not predictable. It affects the climate of much of the tropics and subtropics, and has links (Teleconnection, teleconnections) to higher-latitude regions of the world. The warming phase of the sea surface temperature is known as "El Niño" and the cooling phase as "La Niña". The Southern Oscillation is the accompanying atmospheric oscillation, which is coupled with the sea temperature change. El Niño is associated with higher than normal air sea level pressure over Indonesia, Australia and across the Indian Ocean to the Atlantic Ocean, Atlantic. La Niña has roughly the reverse pattern: high pressure over the central and eastern Pacific and lower pressure through much of the rest of the tropics and subtrop ...

Haiti
Haiti, officially the Republic of Haiti, is a country on the island of Hispaniola in the Caribbean Sea, east of Cuba and Jamaica, and south of the Bahamas. It occupies the western three-eighths of the island, which it shares with the Dominican Republic. Haiti is the third largest country in the Caribbean, and with an estimated population of 11.4 million, is the most populous Caribbean country. The capital and largest city is Port-au-Prince. Haiti was originally inhabited by the Taíno people. In 1492, Christopher Columbus established the first European settlement in the Americas, La Navidad, on its northeastern coast. The island was part of the Spanish Empire until 1697, when the western portion was Peace of Ryswick, ceded to France and became Saint-Domingue, dominated by sugarcane sugar plantations in the Caribbean, plantations worked by enslaved Africans. The 1791–1804 Haitian Revolution made Haiti the first sovereign state in the Caribbean, the second republic in the Americ ...

Hurricane Jeanne
Hurricane Jeanne was the deadliest tropical cyclone in the Atlantic basin since Mitch in 1998, and the deadliest tropical cyclone worldwide in 2004. It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida. After wreaking havoc on Hispaniola, Jeanne struggled to reorganize, eventually strengthening and performing a complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles (three kilometers) from where Hurricane Frances had struck a mere three weeks earlier. Building on the rainfall of Frances and Hurricane Ivan, Jeanne brought near-record flood levels as far north as West Virginia and New Jersey before its remnants turned east into the open ...

Hurricane Ivan Tornado Outbreak
The Hurricane Ivan tornado outbreak was a three-day tornado outbreak that was associated with the passage of Hurricane Ivan across the Southern United States starting on September 15, 2004, across the Gulf Coast states of Alabama and Florida as well as southern Georgia (US State), Georgia before ending in the Middle East Coast of the United States, Atlantic Coast on September 18. The outbreak killed 7 people and injured dozens of others across several states from Florida to Pennsylvania. The hurricane itself killed at least 90 people from the US to the eastern Caribbean Islands. Overall, it produced 120 tornadoes, surpassing the record of 117 that was previously held by Hurricane Beulah during the 1967 Atlantic hurricane season. Ivan also produced 16 more tornadoes than Hurricane Frances, whose associated tornado outbreak struck many of the same regions about ten days earlier. The tornado outbreak was also the largest in Virginia history. Meteorological synopsis On Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
