Severe tropical storms often cause great harm to humans. According to relevant statistics, the annual losses worldwide are as high as 6 to 7 billion US dollars. In addition, the loss of life caused by storm surges, heavy rains, floods, winds, etc. caused by severe tropical storms accounts for 60% of all natural disasters.
The northwest Pacific Ocean, which borders our country, is the most unstable ocean in the world and is also the "hardest hit area" for natural disasters. Every year in midsummer and early autumn, the southeastern coast of my country is often hit by typhoons. Among them, there are nearly 20 typhoons that cause disasters every year, which is four times that of the United States and 30 times that of Russia. In my country's coastal areas, typhoons are the most serious natural disasters.
