中文摘要:
      本文对1979年夏季印度西南季风活跃、中断和撤退时欧亚地区大范围环流和温度场进行了分析.结果表明,该年季风活动的变率与欧亚中高纬环流形势的演变有明显关系.季风活跃期,高空西风带显著北移,西藏高原上空有高空反气旋环流建立、发展,苏联西部阻塞高压发展、维持;季风中断期,西藏高原西部有高空槽存在;苏联西部阻塞高压减弱、崩溃或有高空槽发展;季风的撤退也与东亚冷空气活动关系密切.
英文摘要:
      In this paper the wind and temperature changes over Eurasia during the active,break and withdrawal time periods of the summer monsoon of 1979 is studied.It is shown that the active monsoon regime was characterized by the distinct northward shift of the upper westerlies,establishment and development of upper anticyclonic circulation around the Tibetan Plateau,and development and persistance of blocking high over the western Soviet Union.The break monsoon regime was enhanced by the presence of upper trough over the western part of the Tibetan Plateau and the decay of blocking high or development of a trough system over the western Soviet Union.
