中文摘要: 2010年5月大气环流主要特征如下：北半球高纬度地区极涡呈偶极型，强度偏弱。中高纬度地区环流呈现五波型分布，东亚大槽的强度偏弱，位置偏西。西太平洋副热带高压呈东西向带状分布，脊线较常年偏北，副高西脊点西伸至印度洋一带。2010年5月全国平均气温为16.0 ℃，较常年偏高0.4 ℃。全国平均降水量为80.1 mm，较常年同期偏多13.4 mm。月内出现三次较强冷空气过程和三次沙尘天气过程。

Abstract:The following are the main characteristics of the general circulation of atmosphere in May 2010. There are two polar vortex centers in the Northern Hemisphere. The circulation presents a five wave pattern in middle high latitudes. The intensity of three major deep troughs are weaker than their average conditions. The subtropical high shows a belt figure. The western ridge spot of the high extends to the Indian Ocean. The monthly mean temperature (16.0 ℃) is 0.4 ℃ higher than the same period of normal years and the national mean precipitation (80.1mm) is 13.4 mm more than the same period of normal years. There are three cold air processes and three sand and dust processes in the month.
