| The dependence of asymmetry of wave surface elevation on wind - wave growth state |
|
|
| Abstract: |
| Based on the second - order random wave theory， we studied the dependence of skewnessλ3 which characterizes asymmetry of wave surface elevation on the parameter of wind - wave growth state（inverse wave age Ω and dimensionless fetch X. Approximative analytic relations betweenλ3 andΩ， and betweenλ3 and X are derived. Using the data from experiments in lab’s wind wave - current flume，we verified the applicability of these relations . |
