%X To adjust non-divergent and divergent background wind fields by altimeter wind data, a novel approach, the variational regularization method, is presented. Numerical simulation results show that it is positive to use altimeter wind speed to adjust the background wind field, particularly effective in the altimeter track region. At the same time, the radar backscattering cross-section sensitivity is evaluated, when the backscattering cross-section contains noise, and the result proves that the above method can be used to suppress the noise. Finally, a real case shows that the above method is feasible and effective. This approach is an effective and reliable method of using the altimeter wind data to adjust the sea surface wind.
