2019-2020年更新后的海浪同化产品数据

基于第三代海浪模式WAVEWATCH III，以海气耦合预报系统生成的海表风场作为驱动，构建覆盖印度洋区域的海浪模式。利用最优插值同化方法将卫星观测资料与模式产品进行融合，获取印度洋区域的海浪数值产品数据集。数据集的覆盖范围为30°E~115°E，-30°S~35°N，空间分辨率为1/12°，时间分辨率为1小时，要素包括了有效波高、平均波向、平均波长、谱峰周期和谱峰波向等。Based on the third-generation wave model WAVEWATCH III, a regional wave model covering the Indian Ocean was constructed, driven by the sea surface wind field produced by the air-sea coupled forecasting system. The optimal interpolation assimilation method was employed to fuse satellite observation data and model outputs, thereby generating the numerical wave product dataset for the Indian Ocean. The dataset covers the region of 30°E~115°E, -30°S~35°N, with a spatial resolution of 1/12° and a temporal resolution of 1 hour. The included variables are significant wave height, mean wave direction, mean wavelength, spectral peak period, and spectral peak wave direction, among others.
