摘要：

对比分析了博贺海洋气象观测站2008年7月11日—10月8日期间X波段雷达WaMoSII和浮标观测的三个台风过程的波浪资料,结果表明:在台风登陆前后的高海况下,两种资料的有效波高和平均波向的大小和变化趋势均吻合较好,并且有效波高的相对差异小于平均波向,而在台风来临的前期和后期消退阶段,有效波高和平均波向的大小有一定的差异,但其变化趋势仍具有较好的一致性。

Based on the wave data parameters derived from the X-band radar WaMoS Ⅱ (Wave Monitoring System) and the in-situ buoy wave data of Bohe Marine Meteorological Observing Station from 11^th July to 8^th October, 2008, the comparison between two data sets during the period of the three tropical cyclones is given. The results show that: the significant wave height (SWH) and the mean wave direction (MWD) from the radar measurements are in good agreement with that from the buoy measurements in the processes of the SWH and the MWD sharp increasing. However,with the conformity in the tendency, there is difference in the value between two data sets before the tropical cyclones coming and after their landing.
