Tropical Depression 18W (2009)
Tropical Depression 18W was a weak, short-lived tropical cyclone that brought heavy rains to parts of the Mariana Islands ahead of the more intense Typhoon Melor. Forming from an area of low pressure on September 26, 18W was first monitored by the Japan Meteorological Agency (JMA) as a tropical depression. Tracking generally towards the west, deep convection gradually developed around the system and the Joint Typhoon Warning Center (JTWC) issued their first advisory on the depression early on September 28. Although the depression initially struggled to maintain deep convection, it eventually became better organized and was upgraded to a tropical storm on September 29 by the JTWC. Several hours after reaching this intensity, the system began to rapidly dissipate as its inflow and outflow were severely disrupted by two nearby storms, Parma to the west and Melor to the east. The cyclone fully dissipated near Guam early on September 30 before being absorbed by Typho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariana Islands
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barometric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

Typhoons In Guam
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Parma (2009)
Typhoon Parma, known in the Philippines as Typhoon Pepeng, was the second typhoon to affect the Philippines within the span of a week during September 2009. Typhoon Parma was assigned by PAGASA as Pepeng, when it entered the Philippine Area of Responsibility days after Typhoon Ketsana wreaked havoc on the country. Parma spared the capital and instead lashed the northern part of Luzon island. Parma added to the damage caused by the earlier Typhoon Ketsana, affecting thousands of families on the north, especially on Pangasinan province where the San Roque Dam inadvertently released water to prevent its breach. However, in the first week of October, Parma interacted with the incoming Typhoon Melor on the Pacific (via a Fujiwhara interaction), rendering it stationary as it made landfall on Southern Taiwan. Days later, the greatly weakened Parma retreated back to Luzon making further landfalls on Ilocos Norte and Cagayan. The now severe tropical storm Parma then began to wane its stre ...

Timeline Of The 2009 Pacific Typhoon Season
This timeline documents all of the events of the 2009 Pacific typhoon season which was the period that tropical cyclones formed in the Western Pacific Ocean during 2009, with most of the tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones (including tropical depressions) that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines. During the season, a total of 41 systems were designated as Tropical De ...

Flood Watch
Flood alerts are issued by weather agencies to alert residents that flood conditions are a possibility. Types of flood alerts in the United States In the United States, a flash flood watch is issued by the National Weather Service (NWS) when weather conditions are favorable for very heavy rain that could cause flooding or flash flooding. A watch does not mean that flooding is occurring, only that weather conditions have created or will create a significant risk for it. If flooding occurs, a flood warning or flash flood warning would be issued and immediate action should be taken. A flood warning or flash flood warning is issued when flooding is imminent or already occurring. When flood warnings are issued, it means that area waterways will likely soon be in flood. Not all flood watches suggest that large-scale flooding, such as during landfalling tropical cyclones, is possible. Flood alerts in other countries In Canada, a heavy rainfall warning, which indicates rainfall amounts t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rota (island)
Rota (Chamorro: Luta), also known as the "Friendly Island", is the southernmost island of the United States Commonwealth of the Northern Mariana Islands (CNMI) and the second southernmost of the Marianas Archipelago. In early Spanish records it is called "Zarpana"; the name Rota may have come from the Spaniards possibly naming the island after the municipality of Rota, Spain. It lies approximately north-northeast of the United States territory of Guam. Sinapalo village is the largest and most populated, followed by Songsong village (Songsong). Rota also functions as one of the four municipalities of the CNMI. History In 1521, the first European to see Rota was the lookout on Ferdinand Magellan's ship ''Victoria'', Lope Navarro. However, Magellan's armada of three ships did not stop until they reached Guam, so the first European to arrive in Rota (in 1524), was the Spanish navigator Juan Sebastián Elcano, who annexed it together with the rest of the Mariana Islands on behalf o ...

Tropical Cyclone Warnings And Watches
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atlan ...
