利用10年的热带降雨测量使命（TRMM）降水雷达（PR）观测资料，研究了东南亚地区地面降雨率与降雨系统深度（雨深）之间的关系。结果表明，一般来说，大的地面降水率与深降水系统相关联，但深降水系统不一定与大的地面降水率相对应。这一特点具有区域性。对流雨在陆地上比在海洋上更频繁地发展，而层状雨可以在海洋上比陆地上延伸到更高的高度。无论降雨深度如何，地面小雨率发生的概率最大。对流雨系统比层状雨系统更可能与更强的地面降雨率相关。结果表明，降水系统涉及复杂的微物理过程。降雨深度只是降水的一个特征。地面降雨率与降雨深度之间不存在线性关系。深对流和层状降水系统的反射率廓线可分为三段。其剖面的主要区别是在更高的高度，从4.5公里到19公里。对于浅层层状雨系统，主要存在两段式反射率廓线，而对流系统则以三段式廓线较为常见。
The relationship between surface rain rate and depth of rain system (rain depth) over Southeast Asia is examined using 10-yr Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) measurements. Results show that, in general, a large surface rain rate is associated with a deep precipitating system, but a deep rain system may not always correspond with a large surface rain rate. This feature has a regional characteristic. Convective rain develops more frequently over land than over the ocean, while stratiform rain can extend to higher altitudes over the ocean than over land. A light surface rain rate has the largest probability to occur, regardless of rain depth. A convective rain system is more likely associated with a stronger surface rain rate than a stratiform rain system. Results show that precipitation systems involve complex microphysical processes. Rain depth is just one characteristic of precipitation. A linear relationship between surface rain rate and rain depth does not exist. Both deep convective and stratiform rain systems have reflectivity profiles that can be divided into three sections. The main difference in their profiles is at higher levels, from 4.5 km up to 19 km. For shallow stratiform rain systems, a two-section reflectivity profile mainly exists, while for convective systems a three-section profile is more common.
