【Abstract】 Based on the model of probability statistics of r an dom wave surface, using the relation of Ochi, a nonlinear statistical distributi on of significant wave height is obtained: f(H)=12πHβ1-δβlnHαe -δβlnHαe -12β 2ln 2Hαexp-2δβlnHα The results of the study not only extend the two parameters logarithm-Gaussian d istribution of significant wave height, but also describe the change of the stat istical distribution by using the wave steepness as the nonlinear control parame ter of significant wave height. Applying the result to the analysis of TOPEX alt imeter data in the South China Sea, the theoretical results are identical to the data.更多还原
