Modification (Cont.) The land use, vegetation and soil categories were specified differently between Lake Superior and the other four lakes. This allows small surface fluxes of heat and moisture to develop, but prevents any mechanical effects from discontinuities in surface roughness. The lake surface and substrate temperature were also altered in Sousounis and Fritsch (1994).

Conclusions WRF performs well in simulating both the deep low and shallow low. Lake-air temperature gradient induces vertical heat flux; lake-land roughness contrast contributes to moisture convergence. The Great Lakes’ effect generally strengthens the low system near the surface but is sensitive to the background flow. This effect becomes much more significant for the development of the shallow low and extends to a higher level, tilting downwind. The remote influence of the Great Lakes tends to be subtle in both cases.
