摘要

摘要: 利用黄梅台VP宽频带垂直摆倾斜仪在台风“巴威”（BAVI）和“烟花”（IN-FA）经过期间记录的连续观测资料，通过小波分解和傅里叶变换，分析台风引起的地脉动信号的扰动特征和频谱特性。结果表明：台风扰动幅度随着台风进程呈现出上升—峰值—下降的规律，与台风风速、台风中心与台站距离有良好的相关性；台风引起的地脉动信号的优势频率范围为0.13—0.3 Hz，对应周期为3.3—7.7 s。

Abstract: The continuous observation data recorded by the broadband vertical pendulum tiltmeter at Huangmei Station during the typhoons “BAVI” and “IN-FA” periods were studied. Wavelet decomposition and Fourier transform were used to investigate the disturbance and spectrum characteristics of the microseism signal caused by the typhoon. The results show that the disturbance amplitude has an increase-peak-decrease pattern during the process of typhoon, and has a good correlation with the speed of typhoon and the distance between the typhoon center and the station. The dominant frequency of the microseism caused by the typhoon range from 0.13 to 0.3 Hz, and the corresponding period is 3.3 to 7.7 s.
