本文对西太平洋一九六九年八月份一个西移登陆于中国福建的台风,和一个在海上转向日本登陆的台风在分离点时,从能量场、西风带长波调整、台风的内力和台风外围的风场等几方面进行了物理量的计算及其对比分析、发现它们之间存在着明显的差异,这些差异提供了作台风路径趋势预报时一个判据和参考. In this paper, at a time when a typhoon landed in Fujian Province of China westward in western China in August 1969 and a typhoon that landed in Japan at sea turned to the point of separation, the long-wave adjustment of the energy field, the westerly belt, the internal forces of the typhoon and the typhoon periphery Wind field and other aspects of the calculation and comparison of the physical quantities and found that there are significant differences between them, these differences provide a criterion and reference for the forecast of typhoon path trend.
