| 摘 要： | 利用常规观测资料和FNL资料,对1214号台风"天秤"和1215号台风"布拉万"的相互作用进行了诊断分析,结果表明:"天秤"的路径复杂多变,"布拉万"路径比较稳定,在"天秤"的回旋打转过程中,通过引入兰金涡理论模型,对"藤原效应"引起的双台风互旋角速度进行量化分析,可以看出,"天秤"和"布拉万"之间的"藤原效应"对"天秤"的转向起了决定性的作用,环境场的引导作用较小。通过对台风进行受力分析,可以发现总压力对"天秤"的回旋打转影响较小,而对"布拉万"的移动路径影响显著。"布拉万"强度更强、个头更大,是双台风发生"藤原效应"的主要因素。

| Abstract: | Using the conventional observation data and FNL data, the interaction between binary typhoons Tembin and Bolaven is analyzed. The results show that the path of Tembin was complicated, while that of Bolaven was relatively stable. For the cyclotron period of Tembin, through the introduction of Rankin vortex theory model, the mutual rotation angular velocity between binary typhoons caused by Fujiwara effect is quantitatively analyzed. It can be seen that the Fujiwara effect between binary typhoons Tembin and Bolaven played a decisive role to the steering of Tembin, while the guidance of the environment field had less effect. Through force analysis, find that the total pressure had less effect on the steering of Tembin, but obvious effect on the moving path of Bolaven. Bolaven had stronger strength and larger volume, which is the main cause of Fujiwara effect between binary typhoons Tembin and Bolaven. |
