Tropical Storm Barbara (2007)
Tropical Storm Barbara was the first tropical cyclone to make landfall during the 2007 Pacific hurricane season. The second storm of the season, Barbara developed from a small low-pressure area on May 29 about 235 miles (380 km) southeast of Acapulco, Mexico. The system drifted southward before turning to a steadily eastward motion, and quickly intensified into a tropical storm. Increased wind shear weakened Barbara, though it re-organized to attain peak winds of before moving ashore just west of the border of Mexico and Guatemala. It rapidly weakened over land, and on June 2 the National Hurricane Center discontinued advisories on the storm. Despite expectations that the storm would attain hurricane status, Barbara moved ashore as a small, weak tropical storm. It produced locally heavy rainfall and gusty winds, and in most locations damage was minor. However, in southern Mexico, the rainfall destroyed large areas of cropland, with crop damage totaling 200 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1984 Pacific Hurricane Season
The 1984 Pacific hurricane season featured numerous tropical cyclones, several of which were impactful to land. It was a busy hurricane season with 21 named storms, 13 hurricanes, and 7 major hurricanes, the latter of which are Category 3 or stronger cyclones on the Saffir–Simpson scale. This activity was unusual given the presence of a La Niña, which typically suppresses Central and East Pacific tropical cyclone activity, and only average sea surface temperatures. Seasonal activity began on May 17 and ended on November 8. This lies within the confines of a traditional hurricane season which begins on May 15 in the East Pacific and June 1 in the Central Pacific, and ends on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form. The drought-stricken Hawaiian Islands received beneficial rainfall from Hurricane Douglas in July and Tropical Storm Kenna in August. The remnants of hurr ...

Rainband
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Rainbands within tropical cyclones are curved in orientation. Rainbands of tropical cyclones contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to the formation of a low-level barrier jet. Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salina Cruz
Salina Cruz is a major seaport on the Pacific coast of the Mexican state of Oaxaca. It is the state's third-largest city and is the municipal seat of the municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo Region. The city had a 2005 census population of 71,314, while its municipality, with an area of had a population of 76,219, the state's fourth-largest municipality in population. The port was developed in the late 19th century due to its location at the southern terminus of the Ferrocarril Transístmico, which carried freight across the Isthmus of Tehuantepec. History Salina Cruz, was founded by the Spanish in 1522 under whose command Pedro de Alvarado came. It was given the name "Salina de la Santa Cruz" as its official foundation day was the Catholic day of the holy cross. Salina Cruz is situated near the mouth of the Río Tehuantepec, on the open coast of the Isthmus of Tehuantepec on the Gulf of Tehuantepec, and has no nat ...

Barra De Tonala
Barra (; gd, Barraigh or ; sco, Barra) is an island in the Outer Hebrides, Scotland, and the second southernmost inhabited island there, after the adjacent island of Vatersay to which it is connected by a short causeway. The island is named after Saint Finbarr of Cork. In 2011, the population was 1,174. Gaelic is widely spoken, and at the 2011 Census, there were 761 Gaelic speakers (62% of the population). Geology In common with the rest of the Western Isles, Barra is formed from the oldest rocks in Britain, the Lewisian gneiss, which dates from the Archaean eon. Some of the gneiss in the east of the island is noted as being pyroxene-bearing. Layered textures or foliation in this metamorphic rock is typically around 30° to the east or northeast. Palaeoproterozoic age metadiorites and metatonalites forming a part of the East Barra Meta-igneous Complex occur around Castlebay as they do on the neighbouring islands of Vatersay and Flodday. A few metabasic dykes intru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sipacate
Sipacate is a resort town and municipality on the Pacific coast of Guatemala, in Escuintla Department about west of Puerto San José. It is promoted as a venue for surfing. Being roughly in the center of the Guatemalan coastline, it is used as a breakpoint for storm warnings. The Sipicate-Naranjo National Park is located east of the town. The municipality was formerly a part of La Gomera Municipality just north of Sipacate. Archaeology Some very early human settlements are documented in Sipacate, connected with early agriculture. In sum, sediments sampled in the Sipacate locality appear to document two distinct waves of deforestation associated with early horticulture. The earliest began shortly after 3500 cal B.C. and involved multiple episodes of forest clearance over the next 800 years. The second began after 1700 cal B.C. and coincides with the archaeologically documented presence of Early Formative populations.Hector Neff, Deborah M. Pearsall, John G. Jones, Bárbara Arroy ...

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 ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...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 regi ...
