摘要为热带测雨使命降水雷达（TRMM PR）的潜热廓线估算，提出了一种光谱潜热加热（SLH）算法。该方法使用TRMM PR信息（降水顶部高度，降水率在表面和融化的水平，和雨的类型）从查找表（LUT）中选择加热配置文件。LUT的三种雨类型对流，浅层状，砧雨（深层状融化水平）-来自热带海洋和全球大气耦合海洋-大气响应实验（TOGA COARE）的热带云系的数值模拟，使用云解析模型（CRM）。二维（2D）CRM在以前的研究中使用。指数增长的计算机能力的可用性，导致在三维（3D）CRM模拟多日期变得越来越普遍。在这项研究中，LUT从2D和3D模拟进行了比较。使用3D模拟的LUT...
Abstract The spectral latent heating (SLH) algorithm was developed to estimate latent heating profiles for the Tropical Rainfall Measuring Mission Precipitation Radar (TRMM PR). The method uses TRMM PR information (precipitation-top height, precipitation rates at the surface and melting level, and rain type) to select heating profiles from lookup tables (LUTs). LUTs for the three rain types—convective, shallow stratiform, and anvil rain (deep stratiform with a melting level)—were derived from numerical simulations of tropical cloud systems from the Tropical Ocean and Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE) using a cloud-resolving model (CRM). The two-dimensional (2D) CRM was used in previous studies. The availability of exponentially increasing computer capabilities has resulted in three-dimensional (3D) CRM simulations for multiday periods becoming increasingly prevalent. In this study, LUTs from the 2D and 3D simulations are compared. Using the LUTs from 3D simulation...
