China is becoming increasingly exposed to extreme weather events that experts attribute to climate change.
Torrential rain, scorching summer heat and gale-force winds cause tens of billions of dollars in economic losses annually, disrupting industry and destroying crops.
Footage from state broadcaster CCTV showed rescue workers in Huanggang looking at a badly damaged truck cab that appeared to have been shredded by bits of corrugated steel torn from the roof of a nearby building.

The National Meteorological Centre said northeastern Hubei should brace for further heavy to torrential rain on Tuesday, as well as parts of the southwestern Guangxi region, the southern provinces of Guangdong and Hainan, and the more northerly Jilin, Shandong and Liaoning provinces, among other areas.
