1. Time: The typhoons in the northern hemisphere mainly occur from July to October. Other seasons are obviously reduced.
2. Regionally: mainly concentrated in the northern Bay of Bengal and coastal areas, the southeast coast of China, Japanese and Southeast Asian countries, the Caribbean Sea and the eastern coast of the United States.
In China, typhoon disasters are mainly concentrated in Guangdong, Taiwan Province, Hainan, Fujian and other southern coastal provinces.
Grade and harm of typhoon
1. Typhoon level: According to the maximum wind force (level) near the center of the ground floor, typhoons can be divided into the following levels:
(Source: China Meteorological Bureau)
2. Harm of Typhoon: Typhoon is a disastrous weather system with strong destructive power. When it comes, it is often accompanied by storms and other hazards.
(1) the wind. The maximum wind force near the typhoon center is generally above 8, and its destructive power can often uproot a big tree. Moreover, the strong wind can easily cause the facilities or glass of some high-rise buildings to fall, scrape off power communication lines, and even overturn some cars, hitting pedestrians or causing property losses.
② Heavy rain. Typhoon is one of the strongest rainstorm weather systems. In areas where typhoons pass, it can generally produce 150-300mm of rainfall, and a few typhoons can produce torrential rain of more than 1000mm. In rural areas, low-lying areas or areas with poor drainage systems, it is easy to cause floods, and even in coastal areas, seawalls will burst or seawater will flow backwards; In some mountain areas, it may also cause landslides or mudslides, causing casualties.
③ Storm surge. Storm surge can also be called "storm surge", "storm tsunami", "meteorological tsunami" or "tidal wave". Generally, the spatial range is from tens of kilometers to thousands of kilometers, and the time scale or period is 1-100 hours, which is between the earthquake and tsunami and the low-frequency astronomical tide wave. Storm surges often occur in coastal areas, which will greatly exceed the normal tide level in the affected sea areas and cause major disasters.
Weather changes before and after typhoon crossing the border
【 Rain or shine 】
Before the typhoon: the air sinks and the weather is sultry.
Typhoon approaching: the rain will intensify, and there will be heavy rain within the range of 8-level gale. If there is strong wind in the rain shadow area behind the mountain, there will be no heavy rain.
When the typhoon eye crosses the border: clear sky, no wind and no rain.
Typhoon is far away: the storm is renewed and the wind and rain are getting smaller.
[Air pressure condition]
First down, then up.
Wind power
Overall, it first strengthens and then weakens.
Positive effects of typhoons
What we should pay attention to is that typhoons will not only have bad effects, but also bring some good effects.
Typhoon can bring abundant fresh water resources and alleviate drought.

The tropical and subtropical areas near the equator have the longest sunshine time, and the dry heat is unbearable. The arrival of the typhoon can alleviate the hot and summer weather.

The huge energy flow of typhoon keeps the earth in thermal balance and water balance, and promotes the water cycle.

Typhoons can also increase fishing production. Every time a typhoon blows, it turns over the river, bringing up nutrients at the bottom of the river and sea, increasing the bait, attracting fish to gather near the water surface, and naturally increasing the catch.

Other basic knowledge of typhoon
1. The typhoon center is called typhoon eye, which is concentric circle, and it is divided into vortex wind and rain area and peripheral gale area from inside to outside. The typhoon eye is formed because the wind in the typhoon blows counterclockwise, causing the central air to rotate, and the centrifugal force caused by the rotation is balanced and offset with the wind blowing toward the center, so that the strong wind can no longer converge toward the center, thus forming a windless phenomenon within a few tens of kilometers of the typhoon center, and because of the phenomenon of air sinking and warming, the clouds disappear and the rain disappears, thus becoming a typhoon eye.
2. As the saying goes, "Run Ma Yun, the typhoon is coming". Run Ma Yun’s scientific name is "Broken Cumulus Cloud". The cloud is 1-2 kilometers high, which is a low cloud, and it is made of cumulus clouds shaped like steamed bread. The characteristic of running Ma Yun is that the broken cumulus clouds move rapidly from the southeast coast to the local zenith, which is like a horse race. This kind of cloud occurs in the periphery of tropical cyclone, which indicates that the local area will be attacked by tropical cyclone.
Autumn typhoon
As we all know, typhoons are divided into summer and autumn typhoons. The recent landings of "Bailijia" and "Mangosteen" belong to autumn typhoons, which usually refer to typhoons generated from September to November. Their number is not as much as that in summer, but their influence is enough to stand side by side. The following picture will show you the typhoon in autumn. Please keep it:

[What is a typhoon? 】
Typhoon is a kind of tropical hurricane. The tropical hurricane is categorized in accordance the location: Cyclone (Australian and South of Earth), Hurricanes (in eastern International Dateline), and Typhoon (western Pacific Ocean and China Sea) every typhoon has its own name in alphabetic order. The main damages are caused by flood, roofing materials.
Typhoon is a tropical storm. This tropical storm can be divided into cyclones (Australia and southern hemisphere), hurricanes (east of the date line), and typhoons (western Pacific Ocean and China Sea) according to their locations. Each typhoon has an exact name, and each name is arranged alphabetically. The most threatening things are flying objects, structural damage and floods.
【 Classification of Typhoon 】
Tropical low pressure: the speed of the wind is not less than 33kts per hour. The tropical low pressure can strengthen to violent wind, which is not destructive with a speed of 33kts per hour. But the typhoon-warning centre will sound the alarm when the speed is up to 25kts.
Tropical sub-atmosphere: the continuous wind speed is not less than 33kts (nautical miles). Tropical depression can develop into a powerful storm, but it will not pose a threat to the ground at a speed of 33kts (nautical miles). However, when the tropical low-pressure wind reaches 25kts (nautical miles) per hour, the typhoon warning center will issue an alarm.
