| Abstract: | In this paper we revise the similarity theory for the stably stratified atmospheric boundary layer (ABL), formulate analytical
approximations for the wind velocity and potential temperature profiles over the entire ABL, validate them against large-eddy
simulation and observational data, and develop an improved surface flux calculation technique for use in operational models. |
