Abstract

The impact of Lake Superior on the growth of the boundary layer and lake-effect snow development over Lake Michigan for the case of 16 January 2000 was discussed. It was found that flow over Lake Superior resulted in rapid warming of the near-surface air such that air reaching the northern edge of Lake Michigan was as much as 5°C warmer at -15°C, than if the Lake was not present. The boundary layer growth and turbulence intensification over Lake Michigan was more rapid with Lake Superior. The results show that as the air passes over Lake Michigan, differences in boundary layer height, vertical velocity and cloud amounts decreases, as fluxes from Lake Michigan dominates.
