中文摘要: 2010年10月大气环流特征是:北半球高纬度地区存在两个极涡中心,强度偏弱;中高纬呈现4波型,其中乌拉尔山高压脊偏强,对应大片40 gpm的正距平区;副高强度偏弱。全国平均气温为10.1 ℃,比常年同期(9.6 ℃)偏高0.5 ℃。全国平均降水量为42.6 mm,比常年同期(37.0 mm)偏多15.1%。月内我国主要天气事件有:出现8次主要降水过程,其中,上中旬海南遭受罕见暴雨洪涝灾害;有两个热带气旋生成,其中1013号超级台风鲇鱼登陆我国福建;下旬强冷空气影响我国大部地区;另外,我国中东部发生大雾天气。
Abstract:The following are the main characteristics of the general atmospheric circulation in October 2010. There were two polar vortex centers in the Northern Hemisphere. The circulation presents a four wave pattern in middle high latitudes, in which the strong Ural ridge corresponds to a large 40 gpm positive anomaly area. Strength of the Western Pacific subtropical high is weaker than normal years. The monthly mean temperature (10.1 ℃) is 0.5 ℃ higher than the same period of normal years, and the mean precipitation (42.6 mm) is 15.1% above normal. The major weather events include: 8 precipitation processes occuring, in which a rare heavy rain has struck on Hainan in the first and middle dekad of October; two tropical cyclones generated, with one super typhoon (Chaba, numbered 1013) landed in Fujian; in the last dekad of October, strong cold air outbreak across most areas of China; heavy fog aroused in the central and eastern China.
