Abstract The Tropical Rainfall Measuring Mission (TRMM) satellite measurements from the precision radar and TRMM microwave imager have been combined to yield a comprehensive 3-yr database of precision features (PFs) throughout the global Tropics (±36° latitude). The PFs retrieved using this algorithm (which number almost six million Tropicswide) have been sorted by size and intensity ranging from small shallow features greater than 75 KM2根据其雷达和冰散射特征的大型中尺度对流系统（MCS）进行了对观察到的精度特征的昼夜周期的全面分析土地和海洋地区的降雨和对流强度的昼夜周期。
Abstract The Tropical Rainfall Measuring Mission (TRMM) satellite measurements from the precipitation radar and TRMM microwave imager have been combined to yield a comprehensive 3-yr database of precipitation features (PFs) throughout the global Tropics (±36° latitude). The PFs retrieved using this algorithm (which number nearly six million Tropicswide) have been sorted by size and intensity ranging from small shallow features greater than 75 km2 in area to large mesoscale convective systems (MCSs) according to their radar and ice scattering characteristics. This study presents a comprehensive analysis of the diurnal cycle of the observed precipitation features' rainfall amount, precipitation feature frequency, rainfall intensity, convective–stratiform rainfall portioning, and remotely sensed convective intensity, sampled Tropicswide from space. The observations are sorted regionally to examine the stark differences in the diurnal cycle of rainfall and convective intensity over land and ocean areas. Over ...
