Abstract

Microscale Urban Climate Model(MUKLIMO) was employed to simulate the high resolution prognostic wind fields for support 2002 Worldcup Games. To test the performance and predictability for diagnostic microscale model, wind fields with a single column building were simulated. The simulated wind fields were compared with that of Korea Meteorology Research Institute's $k-\varepsilon$ model. MUKLIMO was successful in representing the microscale wind fields surrounding the building. Based on the initial experiments, MUKLIMO was coupled with mesoscale model(MM5v3.5). The prediction of microscale wind fields at 10 m above ground level around the Daegu and Seoul Worldcup Stadiums were attempted with coupled model, MM5-MUKLIMO. The Root Mean Square Vector Error(RMSVE) of the prognostic wind fields of coupled model were compared with that of the wind fields simulated by MM5 alone which has no microscale urban canopy layer. The results show that RMSVE were reduced by 66% in coupled model. Therefore, it was found that the coupled model(MM5-MUKLIMO) could be used not only for forecast microscale wind fields with urban canopy layer, but also for the prediction of local winds where wind shift is strong.
