HLAFS显式云降水方案及其对暴雨和云的模拟(I)云降水显式方案

EXPLICIT CLOUD SCHEMES OF HLAFS AND SIMULATION OF HEAVY RAINFALL AND CLOUDS, PART I: EXPLICIT CLOUD SCHEMES

将三套显式云降水方案移植、耦合到国家气象中心业务有限区数值预报模式HLAFS中 ,显式云降水方案包括双参数暖云方案、简化混合相云方案和双参数混合相云方案 ,明显地改进了原模式预报系统的湿物理过程 ,特别是对云降水过程的模拟能力。详细介绍了这三套云降水方案的物理过程 。

The development and implementation of three sets of explicit prognostic cloud schemes (two moment warm cloud, simple mixed phased cloud and two moment complicate mixed phased cloud schemes) with the dynamic framework of the limited area numerical weather prediction model HLAFS of the National Meteorological Center are conducted. Significant progress is made in improving the moist physical and simulation ability of cloud physical processes in HLAFS by including the explicit schemes. Three sets of cloud physical schemes and their coupling with the HLAFS dynamical framework are introduced in detail.
