Abstract
The variation of the wind profile power-law exponent (p) with respect to changes in atmo- spheric stability is depicted using the formulation of Ku et al. (1987) for specifying the Monin- Obukhov scaling length (L) under stable atmospheric conditions. The theoretical estimates for the bulk approximation of p as a function of L under stable conditions compare well with power-law exponent data from various sources and the theoretical analysis from Irwin (1979).
