Tropical Storm Adrian (2017)
The 2017 Pacific hurricane season was an above average Pacific hurricane season in terms of named storms, though less active than the previous three, featuring eighteen named storms, nine hurricanes, and four major hurricanes. Despite the considerable amount of activity, most of the storms were weak and short-lived. The season officially started on May 15 in the eastern Pacific Ocean, and on June 1 in the central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2017 by the formation of the season's first named storm, Tropical Storm Adrian, on May 9. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific basin proper (east of 140°W). The season saw near-average activity in terms of accumulated cyclone energy (ACE) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Storm Lidia (2017)
Tropical Storm Lidia was a large tropical cyclone that caused flooding in Baja California Peninsula and parts of western Mexico. The fourteenth tropical cyclone and twelfth named storm of the 2017 Pacific hurricane season, Lidia developed from a large area of disturbed weather west of the Pacific Coast of Mexico on August 31. The storm intensified while moving generally northward or northwestward, peaking with maximum sustained winds of later that day. On September 1, Lidia made landfall in Mexico near Puerto Chale, Baja California Sur, at peak intensity. The storm weakened while traversing the peninsula, ultimately emerging over the Pacific Ocean on September 3, where the storm degenerated into a remnant low. The system brought thunderstorms and wind gusts to Southern California, before dissipating on September 4. In anticipation of the storm, several tropical cyclone warnings and watches were issued in the Baja California Peninsula and other areas along the Gu ...

Salina Cruz
Salina Cruz is a major seaport on the Pacific Ocean, Pacific coast of the List of states of Mexico, Mexican state of Oaxaca. It is the state's fourth-largest city and is the municipal seat of the Municipalities of Oaxaca, municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo de Tehuantepec, Istmo Region. The city had a 2020 census population of 76,660, while its municipality, with an area of had a population of 84,438, the state's fifth-largest municipality in population. The port was developed in the late 19th century due to its location at the southern terminus of the Tren Interoceánico, which carried freight across the Isthmus of Tehuantepec. History Salina Cruz was founded in 1522 by the Spanish, 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 Tehuantepec River, Río T ...

Atmospheric Circulation
Atmospheric circulation is the large-scale movement of Atmosphere of Earth, air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller-scale weather systems – middle latitudes, mid-latitude low-pressure area, depressions, or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory (see chaos theory and the butterfly effect). The Earth's weather is a consequence of its illumination by the Sun and the laws of thermodynamics. The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy and whose heat sink, energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air, and in that process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-pressure Area
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A ...

2010 Pacific Hurricane Season
The 2010 Pacific hurricane season was the least active Pacific hurricane season on record (reliable records began in 1971), tied with 1977 and 1996 season.The season accumulated the second-fewest ACE units on record, as many of the tropical cyclones were weak and short-lived. Altogether, only three of the season's eight named storms strengthened into hurricanes. Of those, two became major hurricanes, with one, Celia, reaching Category 5 intensity on the Saffir-Simpson scale. Despite the inactivity, however, it was the costliest Pacific hurricane season on record at the time, mostly due to Tropical Storm Agatha. The season officially began on May 15 in the eastern North Pacific (east 140°W) and on June 1 in the central North Pacific (from 140°W to the International Date Line). It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of t ...

Tropical Storm Andres (2021)
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of tropical cyclone naming, named storms, but below-average activity in terms of major hurricanes, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean (east of from 140th meridian west, 140°W), and on June 1, 2021, in the Central Pacific (from 140°W to the International Date Line) in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest fo ...

Tropical Depression One-E (2020)
The 2020 Pacific hurricane season was a near average Pacific hurricane season in terms of named storms, featuring 17 (including one unnamed tropical storm which was operationally classified as a tropical depression), but well below average season for hurricanes and major hurricanes, with only 4 hurricanes and 3 major hurricanes forming. Additionally, no tropical cyclones formed in the Central Pacific basin for the first time since 2017. The season officially began on May 15 in the East Pacific Ocean (east of 140°W), and on June 1 in the Central Pacific (from 140°W to the International Date Line, north of the equator; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2020 by the formation of the season's first system, Tropical Depression One-E, on April 25.

Tropical Storm Selma (2017)
Tropical Storm Selma was the first tropical storm on record to make landfall in El Salvador, and only the second Pacific tropical cyclone to attain tropical storm strength east of 90°W, the other being Alma of 2008. The twentieth tropical cyclone and eighteenth named storm of the 2017 Pacific hurricane season, Selma formed from a Central American gyre on October 27. The storm tracked northeastward and reached its peak intensity as a minimal tropical storm before making landfall east of San Salvador, El Salvador early on October 28. Selma rapidly weakened after making landfall, and its remnant circulation dissipated overland at 18:00 UTC on the same day. In anticipation of the storm's arrival, tropical storm warnings and watches were issued for the coast of El Salvador and the Pacific coast of Guatemala. Heavy rainfall associated with the storm and a cold front resulted in flash-flooding and mudslides that caused minor damage in El Salvador. The storm also caused 17 fatalities ...

Hurricane Max (2017)
Hurricane Max was a rapidly-forming tropical cyclone that made landfall in southwestern Mexico, causing minor damage. The sixteenth tropical cyclone, thirteenth named storm, and seventh hurricane of the 2017 Pacific hurricane season, Max developed from a trough of low pressure near the southwestern coast of Mexico on September 13. The storm tracked northeastward under the influence of a mid-level ridge and rapidly strengthened as a result of warm ocean temperatures in its path. Max strengthened into a hurricane on September 14 and peaked as a high-end Category 1 hurricane on the Saffir–Simpson scale shortly before making landfall in the Mexican state of Guerrero. Rapid weakening ensued as Max moved over the mountainous terrain of Mexico, and it weakened below hurricane strength early on September 15. At 12:00 UTC that day, Max dissipated over the mountains of southern Mexico. The Government of Mexico issued numerous tropical storm and hurricane watches and warnings in ...

Tropical Storm Beatriz (2017)
Tropical Storm Beatriz was a short-lived tropical storm that made landfall in the Mexican state of Oaxaca in June 2017. The second named storm of the 2017 Pacific hurricane season, Beatriz developed from a tropical wave which had exited the coast of West Africa on May 18 and crossed Central America, and was designated as Tropical Depression Two-E on May 31. Shortly after being upgraded to a tropical storm, Beatriz made landfall near Puerto Angel, Mexico on the evening of June 1. It subsequently weakened into a tropical depression as it moved ashore, dissipating quickly afterwards. Heavy rainfall from Beatriz caused flash flooding and mudslides in portions of Southwestern Mexico, resulting in seven fatalities. Along its path, Beatriz caused MXN$3.2 billion (US$172 million) in damage. Meteorological history The origins of Beatriz was first traced to a tropical wave which exited the coast of West Africa on May 18. The wave moved westward through the Atlantic and Caribbean with min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
