Post-tropical
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. A tropical cyclone degenerating into a 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 frontal, sometimes still retains winds of 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 over Nova Scotia and all points north in its trajectory. * Remnant low, which is no ...

Hurricane Paulette
Hurricane Paulette was a strong and long-lived Category 2 Atlantic hurricane which became the first to make landfall in Bermuda since Hurricane Gonzalo did so in 2014. The sixteenth named storm and sixth hurricane of the record-breaking 2020 Atlantic hurricane season, Paulette developed from a tropical wave that left the coast of Africa on September 2. The wave eventually consolidated into a tropical depression on September 7. Paulette fluctuated in intensity over the next few days, due to strong wind shear, initially peaking as a strong tropical storm on September 8. It eventually strengthened into a hurricane early on September 13 as shear decreased. On September 14, Paulette made landfall in northeastern Bermuda as a Category 2 hurricane, while making a gradual turn to the northeast. The cyclone further strengthened as it moved away from the island, reaching its peak intensity with 1-minute sustained winds of 105 mph (165 km/h) and a minimum cent ...

2019 Atlantic Hurricane Season
The 2019 Atlantic hurricane season was the fourth consecutive above-average and damaging season dating back to 2016 Atlantic hurricane season, 2016. However, many were weak and short-lived, especially towards the end of the season. Six of those named storms achieved hurricane status, while three intensified into major hurricanes. Two storms became Category 5 hurricanes, marking the fourth consecutive season with at least one Category 5 hurricane, the third consecutive season to feature at least one storm making landfall at Category 5 intensity, and the seventh on record to have multiple tropical cyclones reaching Category 5 strength. The season officially began on June 1 and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Subtropical Storm And ...

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 co ... [...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 (2022), Hurricane Blas and Tropical Storm Celia caused heavy rainfall over southwestern Mexico despite remaining offshore. The season's first major hurricane, Hurricane Bonnie (202 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2011 Pacific Hurricane Season
The 2011 Pacific hurricane season was a below average season in terms of named storms, although it had an above average number of hurricanes and major hurricanes. During the season, 13 tropical depressions formed along with 11 tropical storms, 10 hurricanes and 6 major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year. Despite the decrease in storms, there were several intense and destructive hurricanes this season. Hurricane Beatriz killed four people in Southwestern Mexico. Hurricane Jova killed eight and caused $203.67 million (2011 USD) in damage to Western Mexico. Tropical Depression Twelve-E killed 30 people in Central America. Meanwhile, Kenneth became the strongest November s ... [...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 ...

2021 Pacific Hurricane Season
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average tropical activity in terms of named storms; but featured below-average activity in terms of major hurricanes and a near-normal accumulated cyclone energy (ACE). Five of the season's nineteen named storms made landfall in Mexico, the most since 2018. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; both ending on November 30. These dates historically describe the period each year when most tropical cyclones form in the Pacific basin 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 became the earliest forming tropical storm in the northeastern Pacific proper (east of 140°W longitude) on record. In June, Tropical Storm Dolores made landfall near the border of the Mexican states of Colima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Guambe
Tropical Cyclone Guambe was the third tropical cyclone to make landfall in the country of Mozambique since December 2020, following Cyclone Eloise and Tropical Storm Chalane. The eleventh tropical depression, eighth named storm, and the fourth tropical cyclone of the 2020–21 South-West Indian Ocean cyclone season, Guambe originated from a tropical disturbance in the Mozambique Channel on 10 February. Two days later, the system developed into a subtropical depression that made landfall in Mozambique. The storm proceeded to make a clockwise loop over the country for the next several days, while dumping prolific amounts of rainfall in the region, before re-emerging into the Mozambique Channel on 16 February. Soon afterward, the system strengthened into a moderate tropical storm and was named ''Guambe''. A couple of days later, Guambe underwent rapid intensification, reaching tropical cyclone status on 19 February, and peaking as a Category 2-equivalent tropical cyclone shortly a ...

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 ...

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 rain, showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as Synoptic scale meteorology, 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° a ...
