Abstract Kriging method is an agonic, linear and best estimation for discrete spatial data. The variogram has a great impact on the effect of Kriging method. The least squares method is usually not the best way to obtain variogram, which is not convincing only based on the experience. To deal with this problem, this paper givesanimproved least square method to obtain variogram. The improved method is used toconduct the sea wind field in part of the East China Sea. The cross validationindicates that the error is less than before without human influence.

Key words： least squares method variogram Kriging cross validation
