Should the windows be closed when the typhoon comes?

You must close the doors and windows before the typhoon comes.

Because the typhoon is a tropical cyclone, the wind is much stronger than the common wind in life. If the window is not closed properly when the typhoon comes, it is likely to cause the window to be scraped off. If it is an aluminum alloy window, it should be closed to avoid cracking due to excessive pressure. If you find that the window is loose, you should also seal it.

Aluminum alloy windows at home also have certain typhoon resistance, which is generally about 3-5, but it depends on the size and material of the windows at home. For some high-rise buildings, there are strict requirements on the wind pressure resistance of doors and windows, which need to bear the pressure of more than 5 atmospheres, while ordinary houses can basically resist the wind force of about 3 levels.

The typhoon's wind is very strong, the wind 12- 13, and the wind speed is also very fast. If the window is not properly closed, it is likely to cause indoor objects to be blown away by the wind, resulting in economic losses.

typhoon track

Most typhoons are formed in an area of the northwest Pacific Ocean, which is called typhoon channel, and the most powerful tropical cyclone on the earth occurs most frequently here. Although the typhoon tracks in the northwest Pacific are ever-changing, they can be roughly divided into three categories: First, after the typhoon is generated, it moves from the east to the west of the Philippines, enters the South China Sea, and lands in Guangdong or across the coast.

Generally, typhoons that occur in May and June,10-165438+10 take this route; Second, the typhoon moved from the east of the Philippines to the northwest, crossed the Taiwan Province or the Japanese Ryukyu Islands, and landed along the coasts of Taiwan Province, Fujian, Zhejiang and Jiangsu. After landing, it will either disappear or turn northeast into the sea. The typhoons that occurred in July and August mainly moved along this path.

Third, the typhoon moved directly from the east of the Philippines to the north-northwest direction, and turned east-northeast to Japan at 125. This is the most common parabolic path of typhoon in May,10-165438+10 month. Typhoon originated in the South China Sea, and its moving path is complex and its regularity is not prominent, so it is difficult to sum up a common path.
