Hourly-averaged tall-tower data is used to examine static atmospheric stability as a governor of speed and direction shear in the atmospheric boundary layer. The correlation coefficient between the average diurnal variation in static stability and power law shear exponent is found to be 1.00. Instantaneous correlation of these parameters is 0.68. The influence of static stability on speed shear is hypothesized to be globally applicable. Large magnitudes of wind direction shear are also documented and are found to occur concurrently with large magnitudes of power law shear exponent and hub-height wind speeds greater than 8 m/s. Direction shear is also found to be most prominent in statically stable conditions. Extrapolations of the results in this work suggest beneficial offshore atmospheric conditions in the form of reduced shears and more advantageous diurnal power phasing.
