黄渤海大风的客观相似预报

以MICAPS资料为基础，海平面气压资料为指标，设计了一种通过计算相似系数查找相似形势，制作黄、渤海地区24h大风的客观预报方法，并建立了包括109个大风历史个例资料库。试验结果表明，风速预报的平均误差在20％以下，满足大风预报业务的要求。相似法具有不需依赖国外资料及计算简单迅速的特点，它不仅是现在日常业务的一个补充，更重要的是，它是一种可以在战争等非常情况下使用的预报方法。

Objective Analogous Forecasting of High Winds over Yellow Sea and Bohai Sea

A 24-hour high wind objective forecast method over the Yellow and Bohai Seas was devised through calculating analogous coefficients to identify similar weather patterns, using surface air-pressure as the index, based on the data from MICAPS. A database containing 109 historical high wind events was established. The results of the experiment indicate that the forecasting error is below 20%, which meets the criteria for operational forecasts. The analogous method has the advantagement of being independent of data from foreign countries and being simple and quick in calculation. Therefore, the method can not only complement the daily operational service, but also, more importantly, be used as a weather forecasting method in the case of war and other emergency situations.
