Analysis of the July 2014 Atmospheric Circulation and Weather
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…查看全部>>
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 …查看全部>>
