Tropical Storm Alma
Tropical Storm Alma of the 2008 Pacific hurricane season was the easternmost forming Pacific tropical cyclone on record. It formed within the monsoon trough just off the coast of Costa Rica on May 29. Initially forecast to remain a weak tropical storm, the cyclone rapidly strengthened and developed an eye, before making landfall on May 29 in Nicaragua, near León, with peak winds of . Alma degenerated into a remnant low on May 30, before merging with another approaching tropical wave in the Gulf of Honduras shortly afterward, which became Tropical Storm Arthur on the next day. Alma was the first tropical storm on record to strike the Pacific coast of Nicaragua. In Costa Rica, heavy rainfall caused flooding and landslides, killing two and causing $35 million (USD) in damage. Three people were killed in Nicaragua, one from drowning and two others from electrocution. Five others died in Honduras from an aviation accident likely related to the storm and one other was swept aw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicaragua
Nicaragua (; ), officially the Republic of Nicaragua (), is the largest country in Central America, bordered by Honduras to the north, the Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to the west. Managua is the country's capital and largest city. , it was estimated to be the second largest city in Central America. Nicaragua's multiethnic population of six million includes people of mestizo, indigenous, European and African heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak their own languages and English. Originally inhabited by various indigenous cultures since ancient times, the region was conquered by the Spanish Empire in the 16th century. Nicaragua gained independence from Spain in 1821. The Mosquito Coast followed a different historical path, being colonized by the English in the 17th century and later coming under British rule. It became an autonomous territory of Nicaragua in 1860 and its northernmost part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

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 regi ...

Cabo Blanco Absolute Natural Reserve
The Cabo Blanco Absolute Natural Reserve is a Nature Reserve of Costa Rica, part of the Tempisque Conservation Area in the province of Puntarenas, covering an area of terrestrial and marine on the southern tip of the Nicoya Peninsula near Montezuma-Cabuya and Malpais, Costa Rica, Montezuma-Cabuya and Mal Pais. The site is home to the San Miguel Biological Station which was developed to promote and support teaching, research, and environmental education and has facilities that include classrooms, laboratories and a reference library. The reserve was created in 1963 due to a campaign started by Nils Olof Wessberg and was the first major conservation project in the country. History Up to the 1960s the lands that now constitute the Cabo Blanco Nature Reserve were being depleted of their natural forests for use as farm and pasture land. The emphasis in those days was to develop and increase agricultural production and cattle, and little concern was given to conservation of natura ...

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Hurricane Center
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. The agency, which is co-located with the Miami branch of the National Weather Service, is situated on the campus of Florida International University in Westchester, Florida. The NHC's Tropical Analysis and Forecast Branch (TAFB) routinely issues marine forecasts, in the form of graphics and high seas forecasts year round, with the Ocean Prediction Center having backup responsibility for this unit. The Technology and Science Branch (TSB) provides technical support for the center, which includes new infusions of technology from abroad. The Chief, Aerial Reconnaissance Coordination, All Hurricanes (CARCAH) unit tasks planes, for r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San José, Costa Rica
San José (; meaning "Saint Joseph") is the capital and largest city of Costa Rica, and the capital of the province of the same name. It is in the center of the country, in the mid-west of the Central Valley, within San José Canton. San José is Costa Rica's seat of national government, focal point of political and economic activity, and major transportation hub. San José Canton's population was 288,054 in 2011, and San José's municipal land area is 44.2 square kilometers (17.2 square miles), with an estimated 333,980 residents in 2015. Together with several other cantons of the central valley, including Alajuela, Heredia and Cartago, it forms the country's Greater Metropolitan Area, with an estimated population of over 2 million in 2017. The city is named in honor of Joseph of Nazareth. Founded in 1736 by order of Cabildo de León, the population of San José rose during the 18th century through the use of colonial planning. It has historically been a city of strat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intertropical Convergence Zone
The Intertropical Convergence Zone (ITCZ ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic Equator, it is called the near-equatorial trough. Where the ITCZ is drawn into and merges with a monsoonal circulation, it is sometimes referred to as a monsoon trough, a usage that is more common in Australia and parts of Asia. Meteorology The ITCZ was originally identified from the 1920s to the 1940s as the ''Intertropical Front'' (''ITF''), but after the recognition in the 1940s and the 1950s of the significance of wind field convergence in tropical weather production, the term ''Intertropical Convergence Zone'' (''ITCZ'') was then applied. The ITCZ appears as a band of clouds, usually thunderstorms, that encircle the globe near the Equator. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
