摘要
对15例近海地区热带气旋移向突然左折的规律进行分析，结果表明热带气旋路径左折是由多种因素综合作用的结果。它与环流背景、流场特征、变高场配置、云团作用、双涡旋和冷空气等的影响均有密切关系。在寻找左折路径成因的基础上，通过对研究区内非左折路径的对比分析，建立了左折路径的二级判别方法，供短期业务预报参考。经1994年试用表明效果较好。
There are 15 examples in this article about the sudden left-deflection of tropical cyclone track in the China Seas. According to the researches on the examples,we find that the sudden left-deflection results from the complexity of such factors as the circulation background,the features of current field, highness variation, cloud cluster, double-vortex and cold air.The method to determine,whether the sudden left-deflection will occur or not has been established by comparing the sudden left-deflection with non-left deflection within the special area of research. The method can be used as a reference in short-range operational prediction and has showu successful vesults in the trial operation in 1994.
