【摘要】 介绍一种处理数值预报模式中青藏高原地形的简单方法。即在初始时刻用一个稳定的、平衡的、与外界大气在动力上协调衔接的静止空气堆来取代高原地形,这个方案用于一个五层有限区域细网格原始方程模式中,作梅雨季华中地区短期(24小时)暴雨区预报,效果良好。更多还原

【Abstract】 In this paper,a simple method to deal with the topography of Qinghai-Tibet plateau in a numerical forecasting model is introduced, i.e., at the beginning of the calculations, we replace the plateau by an airmass dome which is stable, balanced, and dynamically coordinated with the real atmosphere surrounding it.This scheme has been applied to a 5 - layer limited regional prediction model for the 24h predictions of heavy rains in central China during the Mei-Yu season. The results are encouraging.更多还原
