摘要
受到全球气候变暖的影响,台风的年暴发频率及其造成的危害都成上升趋势,中国位于西北太平洋沿岸,已成为世界上少数几个遭受台风影响最严重的国家之一。卫星遥感资料因其覆盖范围广、成像面积大、时间分辨率高,已成为台风灾害损失评估的有效资料。在综合近年来台风监测相关研究的基础上,从常规观测资料、气象卫星遥感资料、微波遥感资料等角度出发,对遥感技术在台风监测中的应用现状进行了详细的论述。同时,也对各种数据资源存在的问题以及优势进行了分析,并提出需要加强开展多源数据融合、台风监测系统建设等方面的研究。
Affected by global warming, the annual outbreak frequency of typhoons tended to increase, China is located in the Pacific Northwest, has become one of the world＇s few countries suffered the most serious typhoon. For its coverage of wide area imaging and high time resolution, satellite remote sensing data has become the effective data for typhoon disaster damage assessment. In this paper,based on the researches of recent years in typhoon monitoring, we discuss the application of remote sensing technology in typhoon mo- nitoring status quo from the perspective of conventional observational data,meteorological satellite remote sensing data and microwave remote sensing data. What＇s more, we also analyzed the problems and advanta- ges of the various data resources and pointed out that meteorological satellite remote sensing data is the most popular data in typhoon monitoring,microwave remote sensing data has strong potential. Finally, we suggest that future studies should focus on the multi-source data fusion and the typhoon monitoring system development.
