一个与大尺度模式耦合的边界层温度诊断模式

A DIAGNOSTIC MODEL FOR PBL TEMPERATURE INCORPORATING WITH LARGE-SCALE MODEL

本文提出一个与p—σ五层原始方程模式耦合的边界层温度诊断模式。应用大模式提供的温度场作为边条件数值求解边界层热力学方程得到边界层温度。用FGGE资料一次寒潮过程进行试验,说明结果达到一定精度。本边界层模式原则上可应用于其他大尺度模式。

In this paper, a diagnostic model for PBL temperature incorporating with five layer primitive equation model is suggested. The PBL temperature field is diagnosed by numerically solving the thermodynamic equation of PBL wtth the boundary condition provided by the large scale model. The experiments of the model by using FGGE data during a cold air outbreak show that a certain accuracy has been attained by comparing with observation.This model can also be applied wiih other large scale models.
