There were two major rainfall processes in this month and the monthly mean precipitation over China was 24.9 mm, which is 32.4% more than normal. Monthly mean temperature was 3.1℃, which is 0.2℃ higher than normal. There were four cold air processes in this month, two of which were moderateintensity cold air processes nationwide.
