本文以2006年7月15日的天气过程为例,将遗传算法同化系统应用于修正模式地形即修正模式的问题当中,因为地形是模式的重要参数.提供了一种新的较为有效的修正模式误差的方法。该方法能够反演出一个与初始气象要素场相匹配协调的地形场,从而优化了预报模式.使得该模式有效改善对强降水中心及降水区域的预报。
Basod on the weather event of July 15, 2006, Genetic Algorithm Assimilation System(GAAS) is used in modifying terrain errors which is also the model errors as terrain is an important parameter of model. It provides a new effective method of improving model. This method is able to retrieve the terrain field, whose resolution is matched with Initial meteorological element field; optimize model; and improve the model results varying with the range and intensity of the meso-scale heavy-rain center.
