Methods for wind field Computation from sparse observed wind data

Abstract

Various methods for wind field computation from sparse observed wind data are summarized. The procedure for the computation of wind field based on these methods is as follows.
(1).Computation of grid-point values of wind components by interpolating and extrapolating observed wind data.
(2).Adjustment for the wind vectors obtained in procedure (1) to make them non-divergent An objective analysis procedure is employed to adjust the wind vectors at each grid point. The methods summarized in this report are therefore called an objective analysis technique.
