Numerical simulation of mesoscale atmospheric circulations over the Lake Michigan area

Conference ·
OSTI ID:6414305
A three-dimensional mesoscale numerical model based on simplified second-moment turbulence-closure equations is used for a better understanding of airflow modification by Lake Michigan. Results show airflow characteristics similar to those often observed in the area under late summer conditions. The model sensitivity studies confirm that intensity and location of the lake breeze circulations can vary considerably, for example, if synoptic winds change. Magnitudes of the computed eddy exchange coefficients over water are, as often observed, considerably smaller than the counterparts over land.
