Will the typhoon stop the high-speed rail?

The high-speed rail will stop as soon as the typhoon blows.

Strong winds and heavy rains brought by typhoons may cause safety hazards to high-speed rail lines and vehicles. Strong winds may cause trees to collapse, telephone poles to collapse, etc. Heavy rain may lead to landslides and river flooding. In order to ensure the safety of passengers and trains, relevant departments will decide whether to stop the high-speed train according to the intensity and path of the typhoon. The running speed of high-speed trains is relatively fast, generally around 300 kilometers per hour. When a typhoon comes, the wind speed may exceed the safe operation range of high-speed trains.

In order to ensure the stability and safety of the train, the relevant departments will decide whether to limit the running speed or stop the high-speed train according to the wind speed. Typhoon may cause damage to high-speed rail lines, such as mudslides and landslides. If the line is seriously damaged, the relevant departments may need to close or repair the line, which will lead to the suspension of high-speed trains.

Causes of typhoon formation:

1, ocean warmth

The formation of a typhoon requires the sea surface temperature to reach above 26.5 degrees Celsius, so as to provide enough heat and water vapor to promote the air to rise and form convection.

2, the supply of water vapor

When the ocean surface is warm, the evaporation of water vapor increases, forming a large number of water vapor for typhoon, which makes it develop continuously.

3. Low pressure area

The formation of typhoon needs a low pressure area, which can make the air rise to form convection and rotation.

4. Initial disturbance

The initial disturbance can be tropical waves, convective clouds, etc. , can cause the air to move upwards, thus forming a typhoon.

5. Coriolis force

Coriolis force is a force produced by the earth's rotation, which deflects air to the right in the northern hemisphere and to the left in the southern hemisphere. This deflection will make the initial disturbance gradually rotate and develop into a typhoon.
