Briefly describe the advantages and disadvantages of typhoons to human production and life

A typhoon is a tropical cyclone, when the wind near the center of the tropical cyclone is 12, we call it a typhoon, which generally originates in the tropics, and is called a typhoon that originates in the Pacific Ocean, and a hurricane that originates in the Indian Ocean and the Atlantic Ocean. Tropical cyclones that affect our country generally originate in the Pacific Ocean, mostly occur in the month, and often bring violent storms and rains.

Disadvantages: Strong winds overturn ships and houses, and heavy rains cause local mudslides, floods and other disasters.

Pros: Precipitation can alleviate the drought in the Yangtze River basin in summer and bring cool weather at the same time.

The destructive power of typhoons is mainly manifested by three aspects: strong winds, heavy rain, and storm surge. Strong winds are mainly manifested by low air pressure and high wind speed near the center of the typhoon after the formation of the typhoon, and the strong pressure brought by the typhoon can blow to houses, uproot large trees, fly sand and rocks, and harm people and animals.

Typhoons have a high intensity of heavy rain, high frequency of floods, wide coverage, ferocious and extremely destructive. It is easy to cause flash floods, and may be accompanied by mudslides, landslides, etc. The storm surge of a typhoon is mainly manifested in the fact that when the typhoon moves towards the coast, it will cause the tide level to rise sharply, causing the tide to overflow, the seawall to burst, and the houses to wash away, causing a large number of people** and property damage.

These three destructive forces of a typhoon are sometimes dominated by one, and sometimes all three occur at the same time.

Typhoon precautions

1. Pay attention to typhoon warning information in time and understand the emergency work of typhoon prevention and rescue.

2. When typhoons come, it is often windy and rainy, so the doors and windows at home must be checked to see if they have been closed, and the buildings that are easy to be blown by the wind must be fastened.

3. Try to avoid traveling when the typhoon arrives, because it will be very unsafe at this time, if you have to travel, avoid tall buildings, billboards, brackets and other places.

4. People in low-lying areas that may be flooded should be transferred in time, and do not leave a fluke mentality to stay in the process of time, resulting in unnecessary personnel.

5. After the typhoon comes, it is necessary to pay attention not to turn on electrical appliances and power supplies at home, because in most cases, typhoons are sandwiched with thunderstorms, and many people use household appliances during the typhoon, which causes great trouble.

6. Do not travel to areas where typhoons pass or swim on beaches, and do not go out to sea by boat.

Let's start by looking at how it came to be.

As you can see from the typhoon structure, so.

A huge behemoth, its production must be unique.

right conditions. First, there must be a vast atmosphere of high temperature and high humidity. The temperature and humidity of the bottom atmosphere in the tropical ocean are mainly determined by the sea surface water temperature, and typhoons can only form on the warm ocean surface where the sea surface temperature is higher than 26 27, and the sea water temperature at a depth of 60 meters is higher than 26 27. Second, there should be an initial disturbance of the lower atmosphere converging to the center and the upper atmosphere spreading outward.

Moreover, the high-level divergence must exceed the low-level convergence in order to maintain sufficient updraft, and the low-level disturbance can continue to intensify. Third, the wind speed in the vertical direction should not be too different, and the relative movement of the upper and lower layers of air is very small, so that the latent heat energy released by water vapor condensation in the initial disturbance can be stored in the air column in the eye area of the typhoon, so as to form and strengthen the warm center structure of the typhoon. Fourth, there should be a sufficiently large geostrophic deflection force, and the earth's rotation is conducive to the formation of cyclonic vortices. The geostrophic deflection force is close to zero near the equator and increases towards the north and south poles, and typhoons occur over the ocean about 5 degrees above the equator.

From this, it can be seen that its impact on life is:

1.Crops are damaged, affecting growth and development.

2.During this period, household appliances cannot be used and will be electrocuted.

3.I can't say it when I go out, I definitely can't.

4.If it is a student, depending on the strength of the typhoon, it is decided to suspend classes for a few days.

5.For a country, the loss of economy is certainly devastating.

The following statements about typhoons are false. 2015 Xinjiang Civil Servant.

Choose the fourth, you can't increase fishing production.

d The specific reason is this, the typhoon is coming, and there are still people who go fishing.
