| 摘 要： | 利用福建省地震监测台网资料中有关台风前、台风期间及台风消亡的宽频带速度记录进行了分析研究,提出了用滑动时间窗内的均方根速度作为一种特征能量尺度,研究了台风形成、发展过程中振动能量的变化,统计了均方根速度与台风参数的对应关系.结果初步表明,地震监测资料可以应用于台风的监测与预报.

| Abstract: | This paper makes a research on the broadband velocity records of the total process of typhoon formation and development obtained by Seismic Monitoring Network of Fujian Province,presents a root-mean-square velocity abstracted from moving time window technique as a measure of characteristic energy,studies viberation energy changes of typhoon development process from start to end and gets a corresponding statistical relation between root-mean-square velocity and typhoon parameters.The research result prelimin... |
