Eddy dissipation rate (EDR) profile determined from a minisodar in terrain-disrupted airflow

In Chan (2004), it is demonstrated that the wind measurements from the individual beams of a minisodar could be used to determine the EDR profile of the boundary layer. Some examples of the evolution of EDR profile in terrain-disrupted airflow at the Hong Kong International Airport are presented in this paper, namely, a strong southwest monsoon case and a gale-force easterly wind case associated with a typhoon. Applications and limitations of the EDR profiles provided by the minisodar in the monitoring of low-level turbulence at the airport would be discussed.
