Typhoon weather conditions

Typhoon is a natural disaster, and it is a tropical cyclone with strong wind force formed by the strengthening of warm and humid airflow over the ocean.

Typhoons appear regularly, usually between summer and autumn. But as long as the climatic conditions are suitable, typhoons can occur even in the off-season.

Typhoon is extremely powerful, causing more damage than any natural disaster. It can instantly destroy any object on the surface, and there will be many secondary disasters afterwards. In recent years, due to global warming and global climate anomalies caused by the greenhouse effect, the frequency of typhoons has been increasing, and their power has become more and more powerful.

The destructive power of typhoon is calculated according to the grade. The higher the rank, the greater the power.

Tropical depression, the wind speed is about 17 meters per second, which indicates that a typhoon is coming.

Tropical storm, the wind speed is about 24 meters per second, the trees will shake from side to side, and people will feel obvious resistance when walking in the street. At this time, a typhoon blue warning signal will be issued.

A strong tropical storm with a wind speed of about 32 meters per second. At this time, some saplings will be uprooted, branches of big trees will be broken, and billboards on the streets will be blown down.

Typhoon, the wind speed is about 4 1 m per second. At this time, the intensity of tropical cyclone has reached typhoon level, which can produce powerful destructive power. The telephone poles in the street will be blown down, the roofs of some houses will be torn off, and some inferior buildings will collapse.

Strong typhoon, the wind speed is about 50 meters per second, trees will be uprooted, doors and windows of houses facing the street will be damaged, large billboards will fall, and some bungalows or prefabricated houses will be directly destroyed. Typhoon red warning signal will be released at this time.

Super typhoon, the wind speed is about 52 meters per second or more, which is the highest level of typhoon. Under the super typhoon, any obstacle is not an obstacle and can be directly destroyed. A typhoon can lift the waves 10 meters high in coastal areas to the ground and destroy everything along the coast.

Typhoon is powerful and has a long life cycle, which can last for a week or even longer. Some typhoons can maintain their life cycle by supplementing the lost warm and humid airflow. It has caused great damage to the economy and caused irreparable losses to casualties.

At present, typhoons are unpredictable, and we can't resist them, so we can only prevent them.
