In 2021，extreme weather and climate events occurred widely，frequently，strongly and concurrently in China. Extreme weather and climate events such as rainstorms，droughts，severe convective weather，typhoons，low-temperature freezing and snow disasters，heatwaves and sand storms occurred frequently. Especially in July，Henan extreme rainfall which has broken all the previous records with maximum hourly rainfall rate caused serious losses to the people’s lives and properties. Facing all kinds of extreme weather and climate events，the meteorological department have tried their best to forecast accurately and issue weather warning information timely. They have announced to enter the state-level emergency response and special work status for 26 times and 151 days. They continuously improved the departmental responding mechanism to early warning information，strongly supported the government’s disaster risk reduction and effectively reduced casualties and economic losses. In the context of global warming，meteorological disasters are increasing and extreme weather events become a major risk of human society. We need to pay attention to improve the ability to prevent and respond to extreme weather.
