在实验室中研究了雨引起的表面波。均方根表面偏差被发现随κd/gv而变化，其中κ是雨动能通量，d是滴尺寸，g是重力，v是粘度。波谱相当尖锐，振幅分布似乎是瑞利的性质，至少在定性意义上。对数风廓线表面粗糙度z 0雨在微风的估计，发现是远远大于由于单独的风。
Surface waves due to rain are studied in the laboratory. The rms surface deviation is found to vary as κd/gv, where κ is rain kinetic energy flux, d is drop size, g is gravity, and v is viscosity. Wave spectra are quite sharp, and amplitude distributions appear to be Rayleigh in nature, at least in a qualitative sense. The logarithmic wind profile surface roughness z0 for rain in light winds is estimated and is found to be much larger than that due to the wind alone.
