What are the disasters caused by typhoons? What kind of disasters will be caused by typhoons?

When a typhoon occurs, it is very inconvenient for people to pay attention to the fact that before the typhoon, the doors and windows should be closed to prevent rain, the flower pots on the window sill or balcony should be moved, and the outdoor objects that are easy to be blown should be reinforced. So, what other disasters does a typhoon bring besides its own hazards? Let's take a look.

1. Heavy rain disaster

Typhoon rain has the characteristics of strong coming, high intensity, wide range and long duration, which is very easy to cause waterlogging. Short-term high-intensity precipitation can cause serious geological disasters, flooding of rivers and lakes, collapse of reservoirs, washing out roads, causing interruption of transportation, interruption of water and electricity, damage to factories and houses, and personnel. Typhoon rain and the landslides and mudslides caused by it are one of the main reasons for the high number of deaths caused by typhoons.

2. Gale disasters

Typhoons carry strong winds that are not only ferocious, but also last for a long time, causing great destructiveness. Typhoon winds and the waves caused by them can throw the 10,000-ton giant ship into the air, break it at the waist, or push the giant ship inland; On land, typhoons can uproot trees and topple houses, causing catastrophes.

3. Storm surge disaster

When a typhoon makes landfall at the beginning of the lunar month or two astronomical high tides in the middle of the lunar month, it can cause storm surge disasters that are more severe than heavy rains and strong winds, which can inundate islands, break embankments, and flood inland, and can wipe out hundreds of thousands of people in an instant.

How residents in coastal areas can prevent typhoons

1. Before the typhoon, prepare flashlights, radios, food, drinking water and common medicines in case of urgent needs.

2. The storm surge caused by a typhoon can easily wash away sea ponds, culverts, docks, revetments and other facilities, and may even directly wash away nearby people. Before the typhoon, the tidal flat aquaculture personnel and the downstream of the reservoir at risk of disease'Personnel, temporary sheds and other dangerous areas should be transferred in a timely manner.

3. Before the typhoon, coastal towns and villages should strengthen all kinds of dilapidated housing, workshops, sheds, temporary buildings, projects under construction, municipal public facilities (such as street lights, etc.), cranes, construction elevators, scaffolding, telephone poles, trees, billboards, iron towers, etc., and do not take shelter from the wind and rain in the above places.

4. When a typhoon comes, do not walk on the embankments or bridges of rivers, lakes and seas, and do not drive in areas affected by strong winds.

5. Heavy rain brought by typhoons can easily cause floods, landslides, mudslides and other disasters, and danger signs should be transferred as soon as possible.

6. Do not swim on the beach or sail out to sea during the typhoon.

7. Clean the drainage pipes in time to keep the drainage smooth.

8. In case of danger, please call the local disaster prevention for help.

Typhoons are meteorological disasters that are usually caused by these three aspects. 1. Wind. The winds brought by typhoons can damage or even destroy buildings, bridges, and vehicles on land.

2. Heavy rain. Floods caused by heavy rains are the most dangerous disasters because they are ferocious and destructive. 3. Storm surge.

These disasters can easily induce urban waterlogging, house collapse, flash floods, mudslides, and so on.

Typhoon Blue Warning: Tropical cyclones are likely to be or have been affected within 24 hours, with average winds of 6 or higher along the coast or land, or gusts of 8 or more and may continue.

Yellow Typhoon Warning: Tropical cyclones may be or have been affected within 24 hours, with average winds of 8 or more along the coast or land, or gusts of 10 or more and may continue.

Typhoon Orange Warning: Tropical cyclone may be or has been affected within 12 hours, with an average wind force of 10 or more along the coast or land, or gusts of 12 or more and may continue.

Typhoon Red Warning: Tropical cyclone may be or has been affected within 6 hours, with an average wind force of 12 or more along the coast or land, or gusts of 14 or more and may continue.

Natural disasters caused by typhoons include strong winds, torrential rains, mudslides, landslides, floods, etc.

<> formation of typhoons:

A typhoon is a severe tropical cyclone (wind speed exceeding 32 6 m/s) that occurs in the northwest Pacific Ocean and the South China Sea. A severe tropical cyclone in the Atlantic Ocean or the eastern North Pacific Ocean is called a hurricane, which means that it is called a typhoon in China, the Philippines, and Japan, and a hurricane in the United States. The direct exposure of the tropical sea surface to the sun raises the temperature of the sea, and the evaporation of the sea provides sufficient water vapor.

The condensation of water vapour during the uplift releases a large amount of latent heat, which promotes the further development of convective motion, causing the pressure at sea level to drop, causing the surrounding warm and moist air to flow in and replenish, and then uplift. This cycle results in a positive feedback, the second type of conditional instability (CISK) mechanism. On the vast surface of the sea with the right conditions, the area of influence of the circulation will continue to expand, reaching hundreds to thousands of kilometers.

Because the earth rotates at a high speed from west to east, the air column and the earth's surface cause friction, because the closer to the equator, the stronger the friction, which guides the air column to rotate counterclockwise (the southern hemisphere system rotates clockwise), because the speed of the earth's rotation is fast and the air column cannot keep up with the speed of the earth's rotation and forms a sensory westward movement, which forms what we now call typhoons and typhoon paths.
