摘　　要：台风是全球最具破坏力的气象灾害之一,由于台风过境时现场海洋观测资料相对匮乏,与目前对台风的监测、预报和防灾减灾的迫切需求尚不相匹配。近年来,利用地震学观测资料与技术手段,通过台风激发的地震背景噪声,对台风进行监测的新方法逐渐兴起。本文对近年来有关台风激发地震背景噪声机理、源区分布以及基于地震背景噪声的台风定位追踪、海浪参数反演等研究进展进行综述,分析已取得的研究成果及可能存在的问题,讨论并展望基于地震学的台风监测研究思路与热点。基于地震学的台风监测有望为传统台风观测与研究提供跨学科的观测资料与技术支持。Typhoons are one of the most destructive meteorological disasters all over the world.However,because of the lack of in situ observations under such extreme weather conditions during the typhoon’s passage,typhoon monitoring and forecasting are still not able to meet the needs of typhoon prevention and mitigation.In recent years,a new method of typhoon monitoring based on seismological observations and techniques has emerged and developed,utilizing typhoon-generated seismic noise as a proxy.This paper reviews the recent progress in study of typhoon-induced microseisms,including the generation mechanisms,source location distribution,and its potential implications on typhoon monitoring and ocean wave parameter inversion.Future prospects on seismic monitoring of typhoons are provided and discussed.This newly emerging method may provide interdisciplinary support to traditional observation and investigation of typhoons.
