With the rising of global temperature and intensification of extreme weather events，frequency，casualties and economic losses from meteorological disasters have been increasing globally，which exacerbates the meteorological disaster risks to a certain degree in every country. Degree of disaster risks related not only with the characteristics of extreme events，but also determined by the exposure and vulnerability of hazard-affected bodies. Extreme events usually cause more economic losses in developed countries，but developing countries suffer severe casualties besides for high economic losses. China is one of the countries with the widest affected area by largest number，highest frequency and strongest intensity of meteorological disasters，belongs to high risk country. High death toll and economic losses are two main characteristics of risk level in China. Every country needs to make corresponding efforts to cope with the increasing meteorological disaster risks，and the Paris Agreement reached in 2015 for limiting global warming to 2℃ is a valuable action to reduce the weather risks worldwide.
