提2014年7月环流特征如下：北半球高纬地区为单一极涡，中高纬地区呈5波型分布，巴尔喀什湖附近低槽和东亚大槽强度均较常年偏强；西北太平洋副热带高压带呈东西带状分布，强度与常年同期相当。7月全国平均降水量115．0 mm，较常年同期（120．6 mm）偏少4．6％；全国平均气温为22．3℃，较常年同期（21．9℃）偏高0．4℃。月内共出现8次强降水过程，多站出现极端日降水量。7月共有5个热带气旋（风力8级以上）在西北太平洋和南海活动，生成个数较常年偏多，并有“威马逊”、“麦德姆”2个热带气旋登陆。华南、江南等地出现持续高温天气，全国87个气象观测站发生极端高温事件，74站发生极端日降水量事件。

The main characteristics of the general atmospheric circulation in July 2014 are listed as follows:there is one polar vortex center in the Northern Hemisphere.In the mid-high latitudes,the circulation presents a five-wave pattern among which the troughs near Balkhash Lake and in the East Asia are stron-ger than their climatological mean.The subtropical high shows the distribution of east-west belt and its in-tensity is equivalent to its average state during the corresponding time of the normal years.Meanwhile, monthly mean precipitation amount is 115.0 mm,which is 4.6% less than its climatological mean (120.6 mm).Monthly mean temperature is 22.3℃,higher than its climatological mean (21.9℃).There are 8 severe rainfall events with extreme precipitation records observed at some stations in China.Five tropical cyclones are active over the northwestern Pacific Ocean and the South China Sea,and two of them land China.Long-lasting high temperature events occur in South China and Yangtze River region while ex-treme high temperature events happen at 87 stations and extreme heavy rainfall events at 74 stations in China.
