摘要： 热带气旋引发的海浪是海气相互作用的重要表现，其生成机制与演变规律是物理海洋学研究的前沿课题之一。本研究利用土壤湿度主动/被动（Soil Moisture Active/Passive，SMAP）L波段微波辐射计观测的海面风速和时空对应的第五代欧洲中期天气预报中心再分析资料有效波高数据，系统分析了40个北半球热带气旋个例，并构建了一种融合气旋动力学参数与方位连续修正的二次多项式风浪相关性模型。首先，通过分析2015—2023年间40个北半球热带气旋个例，发现有效波高极大值较多出现在最大风速半径附近，并集中于移动方向右侧约105°；而极小值则集中于移动路径后方约270°；在此基础上，本研究引入停留时间、风场强度因子、标准化半径三个经验参数，结合海面风速数据构建了二次多项式风浪初始模型；针对模型残差的方位依赖，采用三阶傅里叶级数对模型进一步修正，并引入指数函数修正整体非线性误差。对比验证结果表明，新模型与美国国家数据浮标中心浮标有效波高数据的相关系数为0.89，均方根误差为0.96m，平均误差为0.04m，此外，与传统基于象限划分的经验拟合方法相比，新模型在描述有效波高空间分布及其方位连续变化方面精度更高。

Abstract: Ocean waves generated by tropical cyclones are an important manifestation of air-sea interaction, and their generation mechanisms and evolution patterns represent one of the frontier topics in physical oceanography. In this study, using sea surface wind speed observations from the Soil Moisture Active/Passive (SMAP) L-band microwave radiometer and spatiotemporally matched significant wave height data from the fifth-generation European Centre for Medium-Range Weather Forecasts reanalysis (ERA5), we systematically analyzed 40 tropical cyclone cases in the Northern Hemisphere and developed a quadratic polynomial wind-wave correlation model that integrates cyclone dynamic parameters with azimuthally continuous corrections. First, by analyzing the 40 Northern Hemisphere tropical cyclone cases from 2015 to 2023, we found that the maximum significant wave heights predominantly occur near the radius of maximum wind speed and are concentrated at approximately 105° to the right of the moving direction, while the minimum values are concentrated at approximately 270° behind the moving path. On this basis, we introduced three empirical parameters—residence time, wind field intensity factor, and normalized radius—and constructed an initial quadratic polynomial wind-wave model using sea surface wind speed data. To address the azimuthal dependence of the model residuals, a third-order Fourier series was employed to further correct the model, and an exponential function was introduced to correct the overall nonlinear errors. Comparative validation results show that the new model achieves a correlation coefficient of 0.89, a root mean square error of 0.96 m, and a mean error of 0.04 m when compared with significant wave height data from the National Data Buoy Center (NDBC) buoys. Furthermore, compared with traditional empirical fitting methods based on quadrant division, the new model demonstrates higher accuracy in describing the spatial distribution of significant wave height and its azimuthally continuous variations.
