摘要
统计２１年（１９７０－１９９０年）进入预报研究区（１５－２５°Ｎ，１２５°Ｅ以西）的热带气旋移向变化情况，分析移向发生突变的季节变化与地理分布等方面的气候特征。研究了热带气旋移向的突变与副热带高压活动、海岸地形的关系，得到一些有意义的结果，为寻找预报判据提供了气候特征的依据。
ata (1970-1990) of tropical cyclones have been studied by statistical method for those with sudden changes in their moving direction and entered concerned area (15-25°N,West to 125°E). Climatic features, such as seasonal and geographical distributions, have been shown. The relations between the track sudden change and the activity of subtropical high and the terrain factors have been discussed. The results are helpfull in forecasting TC's track sudden change.
