摘要
该文在国家气象中心现行有限区域业务预报模式（ＬＡＭ ）的基础上，把模式的水平分辨率由１°×１°提高到０．５°×０．５°经纬度网格，垂直层次由１５ 层变为２０ 层．在原有物理过程中引入显式降水方案，并使用ＨＬＡＦＳ业务系统的实时资料对１９９７ 年８ 月的一次登陆台风造成的强降水过程进行了个例预报试验。
This paper is based on the operational limited area prediction model run in National Meteorological Center.The horizontal resolution was increased from 1°×1° to 0.5°×0.5° grid in latitude and longitude.The vertical layer was increased from 15 to 20,and the explicit precipitation scheme was introduced into the model physical processes.Using the improved model, a case of forecast experiment on heavy rainfall caused by a landing typhoon in August, 1997 was made,and the results are reasonable.
