Abstract : Extensive surface shear-stress and wind-profile measurements during six separate field studies at Davis, California, indicate a value for the von Karman constant, k, of 0.42. Expressions relating k sub m to the Richardson number for both stable an unstable conditions, based on the Davis data, are presented and compared favorably with the findings of several others. Expressions relating the diabatic wind profile functions to both the Richardson number and z/L are developed and compared with the results of many other researchers. (Author)
