Where do typhoons usually occur?

Typhoon is a kind of bad weather in life, and many areas will be attacked by it, especially the coastal areas of China. The destructive power of typhoons will be relatively large, which will affect people's daily lives, so it is generally necessary to take preventive measures in advance. There may be more typhoons this year, and it is expected that there will be more than 30 typhoons.

How many typhoons will there be in 2022?

It is estimated that there may be more than 30 typhoons, and the specific data will be further predicted. It is still uncertain.

In the northern hemisphere, typhoons mainly occur in summer and autumn, especially in late summer and early autumn from August to September. However, there are exceptions. Most typhoons in the South China Sea, the Bay of Bengal and the Arabian Sea occur in the transitional season. May and September to165438+1October are two peak periods, and there are almost no typhoons in midsummer. The Pacific Northwest is the only sea area in the world that produces typhoons all the year round. In the southern hemisphere, typhoons usually occur from 1 to March, especially 1.

Typhoons in the northern hemisphere usually form in the south of subtropical high. For typhoons in the northwest Pacific, when the subtropical high is strong in summer and the western boundary extends to the east of China, typhoons usually land in China before turning. When the subtropical high is easterly or weak, the typhoon will turn at sea. Typhoons in the North Atlantic usually land west of the United States and Mexico, and then gradually disappear or turn to the westerlies. Of course, there are also some cases of turning or disappearing at sea. In the early days, most typhoons generated in the southern hemisphere were located on the north side of the subtropical high. They first moved west, then turned southeast or landed in Australia and other countries. They are basically symmetrically distributed with the typhoon path in the northern hemisphere.

In the middle and low latitudes, many countries are affected by typhoons. Countries along the Pacific Northwest, such as China, Japanese, Philippine, Vietnamese, Indian and Bangladeshi in South Asia, were severely affected by typhoons. The United States, Mexico and the Caribbean in North America were also severely affected by typhoons. In the southern hemisphere, Australia bears the brunt.

Where do typhoons usually occur?

Typhoons in China are mainly distributed in the southeast coastal areas; Typhoons often occur from June to October.

The main areas are Taiwan Province, Fujian, Guangdong, Hainan, Zhejiang and Guangxi, but other places may also be affected by typhoons or land.

The reason is that these places belong to subtropical areas, and the latitude is relatively low, which is related to the typhoon path. Typhoon tracks generated in the western Pacific affect Fujian, Zhejiang and Taiwan Province provinces in the northwest, Guangdong, Hainan and Guangxi in the west, Guangdong, Hainan and Guangxi in general, and Fujian and Taiwan Province provinces in the north.

Typhoon transit is often accompanied by strong convective weather such as strong wind, heavy rain or heavy rain. The wind in the northern hemisphere rotates counterclockwise (clockwise in the southern hemisphere). On the weather map, the isobar and isotherm of typhoon are about a set of concentric circles. The typhoon center is a low pressure center, which is controlled by the vertical movement of airflow. Calm and sunny; The area near the typhoon eye is a vortex wind and rain area with heavy wind and rain.

What should I do if the typhoon comes?

Listen to and observe typhoon dynamics and early warning information in time;

(2) Obey the arrangement and don't go to dangerous areas such as the seaside and the river;

(3) Reinforce and close the doors and windows, and cut off the outdoor power supply of light box advertisements;

(4) Check the safety of gas, water and circuits;

(5) Put the flowerpots, sundries and other shelves and hangers on the balcony (windowsill, terrace and roof) in place;

(6) Reserve necessary food, medicine and water;

(7) The mobile phone has sufficient power supply, so check the emergency preparedness;

(8) Stop outdoor collective activities and outdoor large-scale indoor gatherings, and stop dangerous operations at heights and outdoors;
