副热带高压对“灿鸿”和“苏迪罗”台风路径的影响

本文利用美国国家环境预报中心(NCEP)6 h一次的全球分析资料及其10 d低通滤波资料对"灿鸿"和"苏迪罗"台风期间的环流场进行分析。结果表明,副高减弱和加强是台风路径北折和维持西行的原因,且在滤波场上该作用更加明显,对台风业务预报更有帮助。

Influence of Subtropical High on Typhoon track of "Canhong" and "Sudiro"

in this paper, the circumferential flow fields during Typhoons Canhong and Sudiro are analyzed by using the global analysis data and the 10-day low-pass filtering data of the National Environmental Forecast Center (NCEP) of the United States for 6 h. It is found that the weakening and strengthening of the subtropical high is the reason for the northward turn of the typhoon track and the maintenance of the westbound travel, and the effect is more obvious and intuitive in the filter field, which is more helpful to the forecast of typhoon operation by forecasters.
