中文摘要: 2011年6月环流特征如下：北半球高纬度地区为单一极涡，强度较常年同期偏弱，西太平洋副热带高压较常年偏强，欧亚中高纬环流较平直，多短波槽活动，季风槽较常年略偏弱，槽前西南气流明显。6月，全国平均降水量为102.8 mm，比常年同期(97.1 mm)偏多5.9%。全国平均气温为20.5℃，比常年同期（19.5℃）偏高1.0℃。月内，我国主要天气气候事件有：长江中下游、华南、西北地区东南部、川渝地区、华北、黄淮、东北南部等地发生暴雨洪涝；有3个热带气旋生成并登陆我国；黄淮等地出现极端高温天气；西北东部、华北、黄淮、江淮北部等地上中旬气象干旱持续发展，下旬干旱缓解；全国23个省（市、区）遭受风雹灾害。

Abstract:The following are the main characteristics of the general atmospheric circulation in June 2011. There was one weak polar vortex center in the Northern Hemisphere. The West Pacific subtropical high is stronger than normal years. In middle high latitudes, the zonal circulation is considered as the main characteristics. The monsoon trough is slightly weaker than normal years. The monthly mean precipitation is 102.8 mm, and is 5.9% more than normal. The monthly mean temperature is 20.5℃, and is 1.0℃ higher than normal (19.5℃). The main weather events in June were rainstorm and flooding occurring at the middle and lower reaches of the Changjiang River, South China, etc. There were three tropical cyclones generated and made landfall in China. Extreme high temperature weather occurred in Huang Huai plain, etc. In east of Northwest China, North China, etc., droughts continued until the last ten days of the month.
