Who knows the common disastrous weather in China in recent years?

China is one of the countries with the most kinds of natural disasters, the most frequent activities and the most serious harm in the world. Among these disasters, climate disasters account for the majority. Generally speaking, meteorological disasters account for 70% of all natural disasters, that is, 70% of disasters are caused by natural disasters. At present, the number of people affected by typhoon, rainstorm, drought, high-temperature heat wave, sandstorm, lightning and other major meteorological disasters in China has reached 400 million every year. According to the statistics of 1990-2006, the direct economic loss caused by meteorological disasters in Chinese mainland in recent 17 years was about18 billion, accounting for 2.8% of GDP on average. Especially in recent years, under the background of global warming, the frequency and intensity of extreme weather events such as super typhoon, high temperature, severe drought, lightning and local strong convection are increasing. The most obvious are floods and droughts.

For example, the flood disaster in the Yangtze River basin in the 1990s was a decade with high flood incidence after the 1950s. In the past half century, the drought-affected areas in the main agricultural areas in northern China have obviously expanded, and this trend is still strengthening. The drought in North China, Southeast China, Huanghuai and other areas has intensified rapidly. Especially in North China, Beijing is also located in North China, and the degree and scope of drought are also increasing, and it is very obvious. For another example, the strong typhoon that affected China was actually affected by global warming to some extent. In 2006, China's typhoon landed early, stayed for a long time, with strong wind and destructive power, which is rare in history. Many friends at home and abroad know that they never know what a super typhoon is. In recent years, super typhoons often appear and have a great impact.
