Abstract

Measurements on wind and temperature fields near the ground as reported by Swinbank and Dyer are re-examined. Through the use of the free convection wind and temperature profiles, H and u* as derived by the present authors have accuracies that are comparable to or better than those obtained earlier through the use of the exponential wind profile and the integrated KEYPS profile.
