What level is Typhoon No.8 in Hong Kong?
Typhoon signal No.8 is one of the warning signals of tropical cyclones in Hong Kong and Macao. Typhoon signal No.8 is called gale or storm signal No.8 in Hong Kong and gale signal No.8 in Macao, including northeast, southeast, northwest and southwest directions of No.8. ..
Since 1884, Hong Kong has adopted a set of circular, spherical and conical signals (commonly known as "typhoon balls", each weighing 25 kilograms) to release tropical cyclones and their approximate positions to Hong Kong ships. When a tropical cyclone approaches Hong Kong, fire a gun to warn residents that strong winds will blow Hong Kong.
In the following decades, the meaning of numbers has been changing. Until 1973 65438+ 10/0/,the warning signals of five tropical cyclones 1, 3, 8, 9, 1 0 were determined. The higher the number, the higher the level. This series of signal systems have been used to this day. However, Hong Kong people still call the typhoon warning by the original hanging standard, that is, "typhoon ball", which is now commonly known as "hanging typhoon ball".
The origin of the word typhoon:
When Hong Kong people mention typhoon signals, the verb is "hang", which is not groundless. As early as 1884, the Hong Kong Observatory began to use a signal system consisting of cylinders, spheres and cones to disseminate information about tropical cyclones to ships and citizens in Hong Kong.
With the increase of population, signal stations gradually spread all over Hong Kong, with a peak in the 1960s. There were 42 signal stations in Hong Kong. However, in recent years, TV stations and the Internet can timely and accurately broadcast the weather, and signal stations have gradually become furnishings. In 2002, the last signal station was closed, and the physical typhoon era officially ended, but the word "hang" remained.
