中文摘要: 2010年8月大气环流主要特征如下:极涡呈单极型,中心略偏于东半球。北半球高纬度环流呈4波型分布,欧洲西北部、新地岛附近为低于-40 gpm负距平所控制。西北太平洋副热带高压面积较常年同期偏大,强度显著偏强,位置异常偏西。2010年8月,全国平均气温为21.4 ℃,比常年同期(20.3 ℃)偏高1.1 ℃。全国平均降水量为108.1 mm,比常年同期(102.6 mm)偏多5.5 mm。月内出现了14次降水过程,共有5个热带风暴生成,其中1008号热带风暴南川在福建登陆。江淮、江南、华南北部、重庆、四川东部及新疆南部等地高温日数异常偏多。

Abstract:The following are the main characteristics of the general circulation of atmosphere in August 2010. The circulation presents a four wave pattern in Eurasian high latitudes. The negative 40gpm is found near Novaya Zemlya and northwestern Europe in the 500 hPa geopotential height anomaly field. The area that the subtropical high covered is larger than normal years. The intensity of the subtropical high is stronger and the western ridge spot is wester than normal years. The monthly mean temperature (21.4 ℃) is 1.1 ℃ higher than the same period of normal years and the national mean precipitation (108.1 mm) is 5.5 mm more than the same period of normal years. There are 14 precipitation processes and 5 tropical cyclones generated with one (Namtheum, numbered 1008) landed China in this month.
