Investigation Of Applying And Pick-up Of Roughness Of Sea Surface

The surface roughness in the Oceans expresses the characteristics of surface undulation that is caused by wind. The roughness depends on air-sea interaction, The surface roughness is very important to marine engineering , air-sea interaction and military affairs. It is difficult for measurement and mostly depends on indirect calculation. All of this blocks our study of the surface roughness. Following the development of technique of Satellite Microcrowave Remote Sensing, we have got many datum about Satellite of Altimater and Scatteromater and proved us method of studing the surface roughness. Based on the other authors study, we think that the roughness is not only the function of the Sea surface wind speed but also the function of dynamical character of wave. We also identify with the roughness that can be expressd by the element of weather or by the element of wave. So we bring forward conception the roughness of Remote Sensing and calculate the roughness of Remote Sensing by the element of weather:z₀ =10exp{-k[(0.087U₁₀β^-0.38+0.82)×10^-3]^-1/2} , by the element of wave: z₀ =10*exp[-13(0.61 + 0.063U₁₀)^-1/2,and by the element of weather and wave:Z₀= (0.50ln H²/L +0.27).The roughness in the Pacific Ocean(120°E～120°W, 50°S～50°N), in the Atlantic Ocean(60°E～10°W , 60°S～60°N) and in the Indian Ocean(20...
