Average Zero-upcrossing Period for the Windsea Timeseries - North Sea - WAM ECMWF

Average Zero-upcrossing Period for the Windsea Timeseries - North Sea - The domain is a lon/lat grid that covers the range [48.5, 57.033] in latitude and the range [-4.05, 9.25] in longitude. The latitude increment is 0.066 degrees, the longitude increment is 0.1 degrees. The spectral analysis is provided every hour. The sea surface is forced by the 1-hourly meteo forecasts provided by the ECMWF北海风浪时间序列平均过零周期数据集：研究区域为覆盖纬度范围[48.5, 57.033]、经度范围[-4.05, 9.25]的经纬度网格，纬度增量为0.066度，经度增量为0.1度。该数据集提供每小时更新的频谱分析结果，海表状态由欧洲中期天气预报中心（ECMWF）发布的逐小时气象预报场强迫驱动。
