1985年8月份,西北太平洋有8个台风活动,其移动特征主要是北上或转向北上,同时出现三个台风群集的复杂运动。本文利用卫星云图对台风的移动趋势作了分析研究。可以清楚地区分开台风的西行和北上趋势,据此在12—48小时以前作出预报。本文还给出台风北上或转向北上的若干卫星云图特征模式。 In August 1985, there were 8 typhoon activities in the northwest Pacific Ocean. The characteristics of their movements were mainly northward or northward, with three complex movements of typhoon clusters occurring at the same time. In this paper, we use satellite imagery to analyze the trend of typhoon movement. The typhoon’s westbound and northward upward trend can be clearly distinguished and a forecast is made 12-48 hours ago. This paper also gives the feature patterns of some satellite images of the typhoon northward or northward.
