摘　　要：本文通过实验室实验的方法,对降雨对海面粗糙度以及风浪和涌浪成长的影响进行了初步的分析;用波面位移数据计算了海浪谱,初步讨论了降雨对波浪成长的影响。分析结果表明:在低风速时,降雨对波浪成长起抑制作用;而在高风速时,降雨对波浪成长起促进作用。其物理机制有待于进一步分析。A series of laboratory experiments are adopted to analyze the effect of rainfall on sea surface roughness,as well as the growth of wind wave and swell.Wave spectrum is calculated using surface elevation recorded by the wave gauges,and the effect of rainfall on wave growth is preliminarily discussed.Results indicate that the growth of wind wave is damped by the rainfall at low wind speed,while it is enhanced at high wind speed.Related mechanisms that account for this phenomenon need further studies.
