Using the 40-year hourly gridded ERA5 reanalysis, we study the offshore patterns of wind variability using the probability density function (PDF) and the power spectral density (PSD). To summarize wind variability, we compute the Weibull parameters from the PDF and the PSD for six spectral bands: interannual, annual, multimonth, storm, diurnal, and semidiurnal. We characterize the storm spectral peak using a Gaussian function in urn:x-wiley:we:media:we2641:we2641-math-0001 frequency space. These parameters are plotted along two pole-to-pole transects through the Atlantic Ocean at 25°W and the Pacific Ocean at 170°W longitude and at 16 current and proposed offshore wind sites. We test the idea that coastal and open-ocean wind statistics may be described by a single set of meridional profiles.

海上风变率的全球模式

使用 40 年每小时网格化 ERA5 再分析,我们使用概率密度函数 (PDF) 和功率谱密度 (PSD) 研究海上风变率模式。为了总结风的可变性,我们根据 PDF 和 PSD 计算六个光谱带的 Weibull 参数:年际、年度、多月、风暴、昼夜和半昼夜。我们在骨灰盒:x-wiley:我们:媒体:we2641:we2641-math-0001频率空间中使用高斯函数来表征风暴频谱峰值。这些参数是沿着两个极对极横断面绘制的,横断面是 25°W 的大西洋和 170°W 的太平洋,以及 16 个洋流和拟议的海上风场。我们测试了沿海和公海风统计可以由一组经向剖面描述的想法。
