探讨数值预报模式中水物质显式方法的表示对降水及降水系统预报的作用

PROBE INTO AN EXPLICIT TREATMENT WATER SUBSTANCE PLAYING A ROLE IN PRECIPITATION SYSTEM IN NUMURICAL SIMILATION EXPREIMENT

本文在细网格11层原始方程模式中采用湿热力过程的显式方法表示,来验证是否能模拟出诸如江淮气旋这样中尺度系统中的风场、气压场及降水。实验表明,用显式模式预报降水有相当大的潜力,而且对地面温度场、高度场、地面气压场预报的改进较大。

In this paper, the model was designed the domain with 11 vertical levels and has been replaced cumulus parameterization with an explicit treatment of moist thermodynamics. The results show: (1) it is vast potential to design an explicit model for precipitation prediction. (2) Taking account of explicit scheme is improved in heign field. Surface pressure field and surface temperature.
