Post-tropical Cyclone
A post-tropical cyclone is a former tropical cyclone that no longer possesses enough tropical qualities to be considered a tropical cyclone. The word may refer to a former tropical cyclone undergoing extratropical transition or a tropical cyclone degenerating into a remnant low-pressure area, low. A tropical cyclone degenerating into a Trough (meteorology), trough or wave, or having it's low level circulation dissipate overland, lacks a cyclonic circulation and is referred as remnants instead of a post-tropical cyclone. However, post-tropical cyclones or remnants can continue producing high winds and heavy rains. Classification Classes Two classes of post-tropical cyclones exist * Extratropical cyclone, which is Weather front, frontal, sometimes still retains winds of Saffir–Simpson scale, hurricane or tropical storm force. Hurricane Paulette (2020) provides a recent example of an extratropical cyclone, in which it no longer has a warm core in higher latitudes when it was ove ...

Blas 2022-06-20 1910Z
Basic Linear Algebra Subprograms (BLAS) is a specification (technical standard), specification that prescribes a set of low-level routines for performing common linear algebra operations such as vector space, vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication. They are the ''de facto'' standard low-level routines for linear algebra libraries; the routines have bindings for both C (programming language), C ("CBLAS interface") and Fortran ("BLAS interface"). Although the BLAS specification is general, BLAS implementations are often optimized for speed on a particular machine, so using them can bring substantial performance benefits. BLAS implementations will take advantage of special floating point hardware such as vector registers or SIMD instructions. It originated as a Fortran library in 1979* and its interface was standardized by the BLAS Technical (BLAST) Forum, whose latest BLAS report can be found on the netlib website. This ...

Hurricane Matthew
Hurricane Matthew was an extremely powerful Atlantic hurricane which caused catastrophic damage and a humanitarian crisis in Haiti, as well as widespread devastation in the southeastern United States. The deadliest Atlantic hurricane since Hurricane Stan in 2005, and the first Category 5 Atlantic hurricane since Felix in 2007, Matthew was the thirteenth named storm, fifth hurricane and second major hurricane of the 2016 Atlantic hurricane season. It caused extensive damage to landmasses in the Greater Antilles, and severe damage in several islands of the Bahamas which were still recovering from Joaquin, which had pounded the archipelago nearly a year earlier. Matthew also approached the southeastern United States, but stayed just offshore, paralleling the Florida coastline. Originating from a tropical wave that emerged off Africa on September 22, Matthew developed into a tropical storm just east of the Lesser Antilles on September 28. It became a hurri ...

Extratropical Transition
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. They are te ...

Tropical Wave
A tropical wave (also called easterly wave, tropical easterly wave, and African easterly wave), in and around the Atlantic Ocean, is a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics, causing areas of cloudiness and thunderstorms. Tropical waves form in the easterly flow along the equatorial side of the subtropical ridge or belt of high air pressure which lies north and south of the Intertropical Convergence Zone (ITCZ). Tropical waves are generally carried westward by the prevailing easterly winds along the tropics and subtropics near the equator. They can lead to the formation of tropical cyclones in the north Atlantic and northeastern Pacific basins. A tropical wave study is aided by Hovmöller diagrams, a graph of meteorological data. West-moving waves can also form from the tail end of frontal zones in the subtropics and tropics, and may be referred to as easterly wav ...

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.

Hurricane Kay (2022)
Hurricane Kay was a strong Category 2 hurricane that made landfall along the coast of the Baja California peninsula. The twelfth named storm and eighth hurricane of the 2022 Pacific hurricane season, Kay originated from an area of disturbed weather that formed near Guatemala. Overall, damage from Kay totaled $3.6 million and three fatalities. Kay's rain was able to help fire fighters who had been struggling to put out the Fairview Fire. Meteorological history On August 29, the National Hurricane Center located two areas of disturbed thunderstorms that had formed south of Mexico. While one of the areas intensified quickly, becoming Tropical Storm Javier, while the other slowly intensified, organizing itself slower than Javier. By September 3, the NHC had given the area a 90% chance of forming. The next day, the area organized itself, strengthening into ''Tropical Depression Twelve'' at 05:00. By 11:00 on September 4, the depression had strengthened into Tropical Storm Kay. Kay c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2022 Pacific Hurricane Season
The 2022 Pacific hurricane season was a fairly active Pacific hurricane season, with nineteen named storms (including two that crossed over from the Atlantic), ten hurricanes, and four major hurricanes forming. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. The first named storm of the season, Hurricane Agatha, formed on May 28, and made landfall two days later at Category 2 strength on the Saffir–Simpson scale, making it the strongest hurricane on record to make landfall during the month of May in the Eastern Pacific basin. In June, Hurricane Blas and Tropical Storm Celia caused heavy rainfall over southwestern Mexico despite remaining offshore. The season's first major hurricane, Hurricane Bonnie, entered into the basin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Blas (2022)
Hurricane Blas was a Category 1 hurricane that brought winds and flooding to several Mexican states in June 2022. The second named storm and second hurricane of the 2022 Pacific hurricane season, Blas developed from a low-pressure area off the coast of southwestern Mexico. It became a tropical depression on June 14. and strengthened into a tropical storm later that same day. Blas became a hurricane the next day, while paralleling the coast. The system reached its peak intensity on June 17, at 15:00 UTC, with maximum sustained winds of and a central pressure of . Later, Blas turned to the west and weakened, becoming a tropical depression on June 20, before transitioning into a post-tropical cyclone on that same day. Damage from the hurricane was minor as it remained offshore. All totaled, Blas was responsible for the deaths of four people in Mexico. Meteorological history On June 7, the National Hurricane Center (NHC) began tracking a disturbance with potential for potentia ...

Cyclone Emnati
Intense Tropical Cyclone Emnati was a tropical cyclone that affected Madagascar, only two weeks after Cyclone Batsirai. The sixth tropical disturbance, the second tropical cyclone, and the second intense tropical cyclone of the 2021–22 South-West Indian Ocean cyclone season, Emnati formed from a zone of disturbed weather that was first noted on 15 February 2022. It continued westward, and steadily intensified before getting named ''Emnati'' a day later. Due to present dry air and wind shear, the storm had struggled to intensify significantly, and it became a category 1-equivalent on the Saffir-Simpson Scale later. After it managed to close off its core from prohibiting factors, the storm quickly intensified into a category 4-equivalent days later, forming a small eye around its CDO. Emnati then underwent a lengthy eyewall replacement cycle, which strongly weakened the storm as it moved closer to Madagascar. Eventually, it weakened back to a category 1-equivalent cyclone before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intense Tropical Cyclone Batsirai
Intense Tropical Cyclone Batsirai was a deadly tropical cyclone which heavily impacted Madagascar in February 2022, becoming the strongest tropical cyclone to strike Madagascar since Cyclone Enawo in 2017. It made landfall two weeks after Tropical Storm Ana brought deadly floods to the island country in late January. The second tropical disturbance, the first tropical cyclone, and the first intense tropical cyclone of the 2021–22 South-West Indian Ocean cyclone season, Batsirai originated from a tropical disturbance that was first noted on 24 January 2022. It fluctuated in intensity and became a moderate tropical storm on 27 January 2022, after which it unexpectedly rapidly intensified into an intense tropical cyclone. It then weakened and struggled to intensify through the coming days due to present wind shear and dry air, where it weakened after some time. Afterward, it entered much more favorable conditions, rapidly intensified yet again to a high-end Category 4 cyclone on t ...
