中文摘要:
      采用TCM-90(台风运动-90)台风现场科学试验资料,对台风FLO,ED个例进行了诊断分析,并做了有关数值试验研究。分析研究结论揭示了台风涡旋作为一动力、热力强迫源或CISK不稳定结构,其与环境场相互作用可激发出动能频散波列;台风扰源通过频散机制可构成类似2维Rossby波的经向波列;台风涡旋的移动路径与上述能量传播特征有一定的相关关系。
英文摘要:
      By using TCM -90 ty phoon field experiment IOP data, the motion characteristics of target typhoons FLO and ED are investigated. The diagnostic analysis and numerical experiment results show that typhoon can beregarded as a source of dynamic and ther-modynamic forcing to it senvironmental at mosphere, and the interaction betwee natyphoon and its environm entmay lead to the dispersion of kinetic energy and excite a hori-zontal Rossby -wave like wave train. The correlation analysis with the diagnostic results shows that the motion of target typhoon agrees with this wave train, and so the diagnosis of typhoon perturbation energy dispersion is meaningful for the forecasting of typhoon motion.
