基于CCMP卫星遥感海面风场数据的渤海风浪模拟研究

Research on wave simulation of Bohai Sea based on the CCMP remotely sensed sea winds

CCMP(Cross Calibrated Multi-Platform)风场数据是一种具有较高的时间、空间分辨率和全球海洋覆盖能力的新型卫星遥感资源。在充分分析CCMP海面风场数据可靠性的基础上,以该卫星遥感海面风场数据为强迫输入项,运用第三代浅水波浪模式SWAN对渤海一次风浪过程进行了模拟,将模拟的结果与T/P、Jason卫星高度计观测得到的有效浪高数据进行比较分析,发现两者相关性达到0.78,模拟结果平均偏高0.3 m。试验表明CCMP卫星遥感风场数据能满足海洋浪高预报需求,能在海洋数值预报和海洋环境研究中发挥重要作用。

Cross Calibrated Multi-Platform（CCMP） remotely sensed wind is a newly released ocean wind dataset which has much higher spatial and temporal resolution,and it can cover the entire ocean surface.After analyzing their reliability,the CCMP wind datasets are used as the input to simulate wind-induced wave with the SWAN model,then the simulated significant wave height（SWH） is analyzed.The comparison between the model result and the data obtained by the radar altimeter shows that the simulated SWH meets the requirements of precision in the sea wave forecasting.
