摘要
2010年6月大气环流主要特征如下:极涡呈两个中心分布并偏离极地;北支锋区偏北,冷空气偏北偏弱;欧亚中高纬度位势高度偏高;低纬度地区多波动;副热带高压偏西,强度偏强。2010年6月,全国平均降水量为95.0 mm接近常年同期,全国平均气温为20.5℃,较常年同期偏高1.0℃。月内南方地区出现持续性强降水过程,共有7次暴雨过程。东北、新疆部分地区出现罕见高温天气。河北、辽宁、山东、江苏等地遭受风雹灾害。
The following are the main characteristics of the general circulation of atmosphere in June 2010. There are two polar vortex centers apart from the polar area.The north branch frontal zone lies northward, so the cold air is weaker.The geopotential height in the Eurasian area is higher.More troughs occur in the low latitude.The West Pacific subtropical high extends to the west of its normal position and its intensity is stronger.The average rainfall is 95.0 mm,near normal.The average temperature is 20.5℃and is higher than normal year for 1.0℃.In this month,consistent heavy rainfall processes hit the Southern China.Exceptional high temperature appears in Northeastern China and some areas in Xinjiang. Strong wind and hail disaster hit Hebei,Liaoning,Shandong,Jiangsu etc.
