【摘要】 <正> 本文用天气图模式指标法,对冬半年(9月——翌年4月)冷空气影响,造成黄海的偏北大风预报进行探讨。按寒潮天气过程500mb的三个基本模式进行分型,每一类型冷空气活动过程,又分为几个阶段。针对每个阶段的关键问题,找出预报指标。此外,对低压的配合问题也进行了探讨。

【Abstract】 The northerly wind resulting by cold-air during winter halfyear is one of the principal disasters over the Yellow Sea. In this paper we use model index method and analysed the cases of the northerly wind over the Yellow Sea. Based on reviewing synoptic maps we devided the northerly wind into three patterns, i. e., the southward cold-trough pattern, the blocken high pressure decay pattern and the trough-ridge movement pattern. According to characteristics of each pattern, we found out forecasting indexes and forecasting clues. The problem of attatched low pressure is also discussed in order to improve the northerly wind forecast.
