地转条件下的浪致辐射应力
Wave-induced radiation stress under geostrophic condition
-
摘要: 首先将Longuet-Higgins提出的海浪辐射应力拓广为自海面至任意深度的单位面积铅直水柱承受的海浪辐射应力,并在此基础上首次给出地转条件下单位水体承受的海浪辐射应力计算式.最后给出单位水体承受的浪致作用力,为在海流数值模拟中便利的考虑海浪对流的驱动作用提供必要的条件.Abstract: The concept of wave-induced 2-dimentional radiation stress firstly proposed by Longuet-Higgins is extended to 3-dimentional radiation stress by taking the earth rotation into account.The mathematical expression of wave radiation stress on the unitarea of water column is derived when considering the earth rotation.The results in this paperwould play a substantial role in the study of wave-driven circulations.
