The HSI is a 0 to 50 point scale, allotting up to 25 points for a tropical cyclone's intensity and up to 25 points for wind field size. [34] Points are awarded on a sliding scale, with the majority of points reserved for hurricane force and greater wind fields. [34] A paper describing the scale was published in 2008. [35]
Vietnam is a southeast Asian country, and is the easternmost country of mainland Southeast Asia. It borders the South China Sea , hence, seeing the increased likeliness of tropical cyclones . Tropical cyclones in this area are considered to be part of the Northwest Pacific basin , and therefore, storms here are considered as typhoons .
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ).
Bão comes from "暴', meaning ferocious, violent or vicious, but in vernacular Vietnamese has come to mean "storm". In 2014, the Vietnamese government issued Decree no.44/2014, introduced five warning levels, but NCHMF only use three out of five levels to issue typhoon warnings: - "Disaster Risk Alert - Level 3" (High Alert), decorated with orange
The Very Severe Cyclonic Storm category was introduced during 1999 alongside Super Cyclonic Storms in order, to replace the previously used Severe Cyclonic Storm with Core of Hurricane Winds. [2] At the time it was the second-highest category with systems having 3-minute sustained wind speeds of between 64–119 kn (119–220 km/h; 74–137 mph ...
A ship, the Crest of the Wave, recorded a minimum pressure of 880 mbar (26 inHg), making it a Category 5 on the Australian region tropical cyclone scale and one of the most intense tropical cyclones in the Southern Hemisphere. The intense cyclone produced the largest recorded storm surge worldwide, estimated at 13 m (43 ft), which washed more ...
Satellite photo of the 24 tropical cyclones worldwide that reached at least Category 3 on the Saffir–Simpson scale during 2024, from Anggrek in January to Chido in December. Among them, Milton (fourth image in the third row) was the most intense with a minimum central pressure of 897 hPa.
