摘要热带降雨测量使命（TRMM）三次野外活动[夸贾林实验（KWAJEX）、热带降雨测量使命亚马逊大尺度生物圈-大气实验（LBA）和南海季风实验（SCSMEX）]期间，由探空网和其他观测资料计算的加热廓线显示出海洋、大陆和季风区之间明显的地理差异。不同的云类型（降水和非降水）在确定总的非绝热加热廓线中起着重要的作用。表观热源Q1的垂直结构的变化，可以与日循环，大尺度强迫，如大气波，在每个位置的降雨阈值。例如，发生在巴西亚马逊的TRMM-LBA在白天主要有深层对流，而发生在太平洋热带辐合带西部的KWAJEX在白天有较浅和中等深度的对流。下午，高…
Abstract Heating profiles calculated from sounding networks and other observations during three Tropical Rainfall Measuring Mission (TRMM) field campaigns [the Kwajalein Experiment (KWAJEX), TRMM Large-Scale Biosphere–Atmosphere Experiment in Amazonia (LBA), and South China Sea Monsoon Experiment (SCSMEX)] show distinct geographical differences between oceanic, continental, and monsoon regimes. Differing cloud types (both precipitating and nonprecipitating) play an important role in determining the total diabatic heating profile. Variations in the vertical structure of the apparent heat source, Q1, can be related to the diurnal cycle, large-scale forcings such as atmospheric waves, and rain thresholds at each location. For example, TRMM-LBA, which occurred in the Brazilian Amazon, had mostly deep convection during the day while KWAJEX, which occurred in the western portion of the Pacific intertropical convergence zone, had more shallow and moderately deep daytime convection. Therefore, the afternoon heigh...
