The main cause of disasters caused by typhoons is storm surge caused by typhoons. What is a storm surge?

Generally speaking, storm surge is the amount of seawater lifted by typhoon. The formation of storm surge is mainly due to the pressure of airflow, which pushes the coastal seawater to the shore, and the typhoon's wind has added a lot of strength to this force. So the storm surge is affected by the airflow, pushing the seawater to the shore.

Typhoon storm surge often brings violent wind and waves, especially when encountering astronomical climax, which will produce high-frequency tide level, lead to flooding, seawall burst, destroy houses and various building facilities, flood towns and farmland, and cause a large number of casualties and property losses. Storm surge will also cause coastal erosion and land salinization caused by seawater intrusion.

Storm surge (storm? Tide is a catastrophic natural phenomenon. When the sea water rises and falls abnormally due to severe atmospheric disturbance, such as strong wind and sudden pressure change (usually referring to typhoon, extratropical cyclone and other disastrous weather systems), and it is superimposed with astronomical tide (usually referring to tides). According to the nature of storms, storm surges are usually divided into temperate storm surges caused by temperate cyclones and typhoon storm surges caused by typhoons.

This kind of disaster is mainly caused by strong wind and high water level. The reason for this is that there is strong wind along the coast. The strong winds formed in the ocean are mainly typhoons and extratropical cyclones. Typhoons occur in tropical oceans and are very destructive. Internationally known as tropical cyclones, in the Atlantic Ocean and the Northeast Pacific Ocean. Storm surge is a serious marine disaster, which is extremely harmful to the life of coastal people. Property and the economic development of coastal areas have great influence. In order to use less? Economic input, in order to obtain the greatest social benefits, we must develop the coastal economy? Fully consider the hazards of storm surge. In order to effectively alleviate the disaster? We must actively carry out storm surge warning, storm surge forecast and storm surge water increase. Monitoring and other work.
