Abstract

The impact of mixing-length formulations on wind and temperature predictions in two TKE PBL schemes is analyzed. The 3-D nonhydrostatic MM5 model is used to compare the two PBL schemes, G-S and Eta. Comparisons between G-S and Eta schemes suggest that the different simulation of Vscf may be generated by the different downward momemtum transport which depends on the specification on mixing length. The results show that the MM5 1-D GUI model produces a different cycle of Vsfc compared to the area averaged Vscf using MM5 3-D model.
