1509号台风灿鸿期间“朱家尖-嵊山”高频地波雷达数据分析

摘要

2007年在朱家尖和嵊山布设了小型阵变频高频地波雷达,对共同覆盖范围内的舟山海域进行风、浪、流的业务化探测.2015年7月11日,1509号台风灿鸿在朱家尖沿海登陆,之后继续向北偏东方向移动,台风中心经过高频地波雷达探测海域.本文将台风期间高频地波雷达的探测数据分别与定点浮标观测数据和ASCAT卫星遥感大面积风场数据进行了对比分析.结果表明,高频地波雷达在台风期间较好地反映了舟山海域流场特征和风场分布情况,高频地波雷达的探测数据精度满足指标要求,验证了高频地波雷达在复杂海况条件下具有合格的探测性能.%High Frequency Surface Wave Radar(HFSWR) with small circular array was deployed in Zhujiajian and Shengshan to detect the winds,waves,and currents in the overlapping area in 2007.No.1509 Typhoon Chan-hom landed in the coastal areas of Jujiajian,and then moved north by east,passing the HFSWR detection area.The HFSWR inversed results were compared to anchored buoy observed data and the large area wind data from ASCAT satellite remote sensing respectively.The results of comparison indicate that HFSWR data basically reflect the real distribution of wind and current at Zhoushan area during Typhoon Chan-hom,showing the HFSWR's applicability in detecting the winds and currents under high sea state conditions.
