摘要分析了1998-2001年国际卫星云气候计划（ISCCP）深对流数据库和热带使命测雨任务（TRMM）降水资料中发现的青藏高原夏季对流系统（CS）的基本特征，包括CS的起源、分布、轨迹、发展、生命周期、对流强度和降水。夏季对流系统在横断山地区有一个优势中心，在雅鲁藏布江流域有一个次级中心。与这些对流系统相关的降水在青藏高原中东部地区占总降水的60%以上，在其东南部的邻近地区占30%-40%。CS的平均生命周期约为36小时; 85%的CS在其开始的60小时内消失。大约50%的CSs没有移出西藏地区，其余的则分为向东和向南移动的成分。这些从西藏解放军出来的士兵...
Abstract Summer convective systems (CSs) initiated over the Tibetan Plateau identified by the International Satellite Cloud Climatology Project (ISCCP) deep convection database and associated Tropical Rainfall Measuring Mission (TRMM) precipitation for 1998–2001 have been analyzed for their basic characteristics in terms of initiation, distribution, trajectory, development, life cycle, convective intensity, and precipitation. Summer convective systems have a dominant center over the Hengduan Mountain and a secondary center over the Yaluzangbu River Valley. Precipitation associated with these CSs contributes more than 60% of total precipitation over the central-eastern area of the Tibetan Plateau and 30%–40% over the adjacent region to its southeast. The average CS life cycle is about 36 h; 85% of CSs disappear within 60 h of their initiation. About 50% of CSs do not move out of the Tibetan region, with the remainder split into eastward- and southward-moving components. These CSs moving out the Tibetan Pla...
