Abstract : An evaluation is made of a proposal presented by the author in an earlier paper, according to which optimum interpolations might be made of wind vectors at network grid intersections using aerological station soundings. The empirical evaluation of the accuracy of this proposed scheme involved experimental interpolation for the station data; these results were then compared with the measured data for the u and v fields at three levels (850, 500, and 300 mb) for nine situations. Data from about 200 stations were used in the analyses; the mean square errors of u and v were calculated and compared for each of these levels, i.e., velocities of about 5, 7 and 11 m/sec. The interpolation analysis demonstrated close agreement between the theoretical and empirical data and, therefore, that the theoretically derived values are good indicators for a true accuracy analysis.
