【摘要】：COARE(Coupled Ocean-Atmosphere Response Experiment)算法是国际上较先进的计算海气界面通量的算法。最新的COARE 3.0算法包含TY01方案和O02方案两种考虑真实海浪状态的海面空气动力学粗糙度方案;当有效波高和谱峰周期缺省时,利用Taylor01风浪特征量参数化方案可对它们进行参数化。在此基础上引入自主设计的WHP(Wind-wave significant wave Height and dominant wave Period)风浪特征量参数化方案和三种海面空气动力学粗糙度方案,即SCOR方案、GW03方案、PYP07方案以及更简单的Andreas12、Vickers15摩擦速度算法,利用NDBC(National Data Buoy Center)浮标数据、解放军理工大学风浪流水槽实验数据,针对中高风速条件(10 m/s≤U10≤25 m/s)比较上述方案对摩擦速度的预测效果。结果表明:WHP方案在COARE 3.0算法中的应用效果优于Taylor01方案,且新引入的SCOR、GW03、PYP07海面粗糙度方案对风浪特征量的观测误差敏感性更小、稳定度更高;水槽实测数据的对比结果表明,WHP方案结合SCOR海面粗糙度方案计算的摩擦速度与实测值最接近;引入其他三种实测数据的检验结果表明,原始COARE 3.0算法会低估摩擦速度,而WHP方案结合SCOR海面粗糙度方案能更准确地预测摩擦速度随10 m风速的增长趋势。
[Abstract]:The COARE(Coupled Ocean-Atmosphere Response experimental algorithm is an advanced algorithm for calculating the air-sea interface flux in the world.The latest COARE 3.0 algorithm includes two schemes, TY01 scheme and O02 scheme. When the effective wave height and spectral peak period default, they can be parameterized by using the Taylor01 wind wave characteristic parameter scheme.On this basis, the parameterization scheme of WHP(Wind-wave significant wave Height and dominant wave Period-wind wave characteristic and three kinds of surface aerodynamics roughness schemes, namely SCOR scheme GW03 scheme and PYP07 scheme, and a simpler Andreas 12 Vickers15 friction velocity algorithm are introduced.Using the data of NDBC(National Data Buoy center buoy and the experimental data of wind wave current flume of PLA University of Technology, the prediction effect of the above scheme on friction velocity is compared for the medium and high wind speed conditions (10 m / s 鈮，
