The northwestern Pacific subtropical high was stronger than normal. The monthly mean precipitation amount was 138.9 mm, which is 15.2% more than normal (120.6 mm). The monthly mean temperature was 22.4℃, being 0.5℃ higher than normal. There were 11 heavy rainfall processes with extreme precipitation records observed at some stations. Four tropical cyclones appeared over the South China Sea and the northwestern Pacific Ocean with three of them landed on China.
