摘要利用2006 - 2009年夏季（6 - 8月）的CloudSat和云-气溶胶激光雷达及红外探测卫星（CALIPSO）资料，对青藏高原-南亚季风区（TP-SAMR）的深对流进行了分析。定义了TP、高原南坡（PSS）和SAMR三个分区，并对各分区的深对流特征（如发生频率、内部垂直结构、系统大小和局地环境）进行了比较。为了在更广泛的背景下将它们投射，还讨论了与TP-SAMR具有某些相似性的另外四个区域：东亚（EA），热带西北太平洋（NWP）以及北美西部和东部主要调查结果如下：1）与TP-SAMR的其他两个亚区相比，TP上的深对流较浅，不太频繁，并且嵌入较小尺寸的对流系统，但云顶的密度更大这些特征…
AbstractDeep convection in the Tibetan Plateau–southern Asian monsoon region (TP–SAMR) is analyzed using CloudSat and Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) data for the boreal summer season (June–August) from 2006 to 2009. Three subregions are defined—the TP, the southern slope of the plateau (PSS), and the SAMR—and deep convection properties (such as occurrence frequency, internal vertical structure, system size, and local environment) are compared among these subregions. To cast them in a broader context, four additional regions that bear some similarity to the TP–SAMR are also discussed: East Asia (EA), tropical northwestern Pacific (NWP), and western and eastern North America (WNA and ENA, respectively).The principal findings are as follows: 1) Compared to the other two subregions of the TP–SAMR, deep convection over the TP is shallower, less frequent, and embedded in smaller-size convection systems, but the cloud tops are more densely packed. These characteristi...
