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 . |
Key words: skewness inverse wave age dimensionless fetch |
