摘要
Probability distributions of wave phases in association with distributions of surface elevations are studied with wave records. Wave records of different nature are used for comparison. These are surface fluctuations acquired during wind wave flume experiments, representing wave generation under strong wind; and wave records measured in the northern part of Taiwan for waves in natural environments. Three probability models, the unifrom distribution, the beta distribution, and a model from Tayfun and Lo (1989) are adopted to study the possible distributions of wave phases. It is found that when surface elevations become skewed, wave phases deviate from the usually assumed uniform distribution and a better model would be the beta distribution.
