Cyclone Ernest
Intense Tropical Cyclone Ernest was one of two intense tropical cyclones in the 2004–05 South-West Indian Ocean cyclone season. The eighth tropical disturbance of the season, Ernest formed from a persistent area of thunderstorms in the central Indian Ocean. It initially moved southwestward, intensifying into Tropical Storm Ernest on January 20 while moving into the Mozambique Channel. After hitting Mayotte, the storm quickly intensified to reach peak winds of 165 km/h (105 mph 10 minute winds) off the western coast of Madagascar. Ernest weakened slightly before striking the southwest portion of that country on January 23, producing widespread flooding and gusty winds. The next day the cyclone became extratropical before dissipating on January 25. On Mayotte, Ernest produced peak wind gusts of 98 km/h (61 mph). The storm drew moisture away from Malawi, causing a nine-day period of dry conditions. A few days after Ernest struck Madagascar, ...

Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. Th ...

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] |

Cyclone Gafilo
Very Intense Tropical Cyclone Gafilo was both the List of the most intense tropical cyclones#South-West Indian Ocean, most intense tropical cyclone ever recorded in the South-West Indian Ocean tropical cyclone climatology, South-West Indian Ocean and the most intense tropical cyclone worldwide in 2004. Being unusually large and intense, Gafilo was the deadliest and most destructive cyclone of the 2003–04 South-West Indian Ocean cyclone season. According to the EM-DAT International Disaster Database, Gafilo killed at least 363 people. Gafilo also caused about $250 million (2004 USD) damages in Madagascar, which makes it one of the most devastating storms to hit the country on reliable record. Forming south of Diego Garcia, it intensified into a moderate tropical storm on 3 March. One day later, Gafilo became a tropical cyclone, and it ultimately intensified into a very intense tropical cyclone on 6 March, prior to making landfall over Madagascar early on the next day.

Toliara
Toliara (also known as ''Toliary'', ; formerly ''Tuléar'') is a city in Madagascar. It is the capital of the Atsimo-Andrefana region, located 936 km southwest of national capital Antananarivo. The current spelling of the name was adopted in the 1970s, reflecting the orthography of the Malagasy language. Many geographic place names, assigned French spellings during the colonial period, were altered following Malagasy independence in 1960. The city has a population of 168,758 in 2018. As a port town it acts as a major import/export hub for commodities such as sisal, soap, hemp, cotton, rice and peanuts. History In the 17th century, French buccaneers landed in the bay of St. Augustine near the Tropic of Capricorn, and founded the city to maintain commercial relations. It was not until the colonial period, after 1897, when the city really grew: with the efforts of Joseph Gallieni to install French administrative services, previously isolated on the island of Nosy Ve, ...

Landfall (meteorology)
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there. Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as friction with the ...

The U.S. National Weather Service defines a gale as sustained surface winds moving at a speed of between 34 and 47 knots (, or ).National Weather Service Glossary s.v "gale" Forecasters typically issue gale warnings when winds of this strength are expected. In the , a gale warning is specifically a maritime warning; the land-based equivalent in National Weather Service war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridge (meteorology)
A ridge or barometric ridge is a term in meteorology describing an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar ...

Sea Surface Temperature
Sea surface temperature (SST), or ocean surface temperature, is the ocean temperature close to the surface. The exact meaning of ''surface'' varies according to the measurement method used, but it is between and below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can affect SST's on multi-decadal time scales, a major impact results from the global thermohali ...

Rapid Deepening
In meteorology, rapid intensification is a situation where a tropical cyclone intensifies dramatically in a short period of time. The United States National Hurricane Center defines rapid intensification as an increase in the maximum sustained winds of a tropical cyclone of at least in a 24-hour period. Necessary conditions External In order for rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely warm (near or above ), and water of this temperature must be sufficiently deep such that waves do not churn deeper cooler waters up to the surface. Wind shear must be low; when wind shear is high, the convection and circulation in the cyclone will be disrupted. Dry air can also limit the strengthening of tropical cyclones. Internal Usually, an anticyclone in the upper layers of the troposphere above the storm must also be present for extremely low surface pressures to develop. This is because air must be converging towards the low p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
