The current naming method of typhoons is that the countries and regions surrounding the typhoon draw up a naming list.
The Typhoon Committee under the World Meteorological Organization held a meeting in 1997 and decided to adopt a new unified nomenclature for tropical cyclones generated in the northwest Pacific and the South China Sea starting in 2000. Typhoon names were provided by 14 countries and regions including China, Japan, the United States, Thailand, and South Korea, with each country (region) proposing 10 names, ultimately forming a naming list including 140 typhoon names.
After that, the names of typhoons are recycled in the specified order according to this table. When a tropical cyclone in the northwest Pacific or South China Sea is determined to have reached the intensity of a tropical storm, it is given a name according to the naming table and is also given a four-digit number, where the first two digits are the year and the last two digits are the sequence number.
Direct disasters caused by typhoons
1. Strong winds
The wind speed of typhoons is mostly above 17 meters/second, or even above 60 meters/second. According to measurements, when the wind reaches level 12, the wind pressure per square meter on a plane perpendicular to the wind direction can reach 230 kilograms. Therefore, when a super typhoon comes, the strong winds and huge waves it brings can throw up or even break coastal ships; it is also enough to damage or even destroy buildings, bridges, vehicles, etc. on land.
2. Heavy rain
When a typhoon lands, the center of the rainfall can drop 100 to 300 mm, or even 500 to 800 mm of heavy rain in a day. Floods caused by typhoons are fierce and destructive, and are the most dangerous disasters.
3. Storm surge
When a typhoon moves towards the land, due to the strong winds and low pressure of the typhoon, the sea water accumulates strongly towards the coast, the tide level rises sharply, and the water waves are overwhelming. It generally presses toward the coast, causing the tide to overflow, seawalls to burst, destroying houses and various construction facilities, flooding towns and farmland, and causing a large number of casualties and property losses.
