Abstract:
The main characteristics of the general atmospheric circulation in July 2012 are as follows: The circulation presented a pattern of two highs and one deep trough at the middle high latitudes over Eurasia, and the upper troughs were active. The northwestern pacific subtropical high was weaker than normal. The monthly mean precipitation amount was 135 mm, which is 14.4% more than normal. The monthly mean temperature was 22.1℃, being 0.4℃ higher than normal. There were 8 heavy rainfall processes, and extreme precipitation records were observed at many stations. Four tropical cyclones were generated over the northwestern Pacific, however, only one landed on China. The number of high temperature days is obviously more than normal in some areas, such as Jiangnan, Jianghuai, Jianghan, and huanghuai etc.
