中文摘要: 2017年6月大气环流的主要特征是极涡偏强且呈单极型分布,中高纬环流呈多波型,西太平洋副热带高压强度较常年偏弱。6月全国平均气温20.3℃,较常年同期偏高0.3℃;全国平均降水量112.3 mm,比常年同期(99.3 mm)偏多13%,长江流域入梅时间较常年偏早。我国南方地区有6次区域性暴雨过程,部分地区暴雨洪涝重;与此同时,东北、华北等地少雨高温,干旱持续时间较长;月内今年第2号台风苗柏在广东深圳登陆;全国19个省(区、市)遭受风雹灾害。
Abstract:The main characteristics of the general atmospheric circulation are as follows. There was one polar vortex center in the Northern Hemisphere, stronger than usual. The circulation in Eurasian middle high latitudes showed a multiwave pattern. The strength of Western Pacific subtropical high was a little weaker than in normal years. The monthly mean temperature in June was 20.3℃, 0.3℃ higher than the normal value, while the monthly mean precipitation amount was 112.3 mm which is 13% more than normal. The plum rains or Meiyu started earlier in the year of 2017. Typhoon Merbok landed in Guangdong Province in this month, which is the first landing typhoon in China this year. There were 6 heavy precipitation processes in the South of China, and in some places severe rainstorm and floods occurred. Meanwhile, Northeast China and North China rained less with high temperature during this month, causing drought to last for a long time. In addition, strong wind and hail disasters hit 19 provinces.
