This paper describes the set-up and application of a non-hydrostatic Canadian meteorological numerical model (MC2) for mesoscale simulations of wind field and other meteorological parameters over the complex terrain of Hong Kong. Results of the simulations of one case are presented and compared with the results of radiosonde and aircraft measurements. The model is proved capable of predicting high-resolution,three-dimensional fields of wind and other meteorological parameters within the Hong Kong territory, using reasonable computer time and memory resources.
