The monthly mean precipitation is 30.8 mm, 14% less than normal. The monthly mean temperature is 11.1℃, which is 0.8℃ lower than normal years. There are four cold air processes affecting China during this month. Typhoon Fitow makes landfall in southern part of East China and northern part of South China, bringing a severe rainfall process.
