500 m Positive Vertical Motion

The following four panels show the 2000 UTC (1500 LST) 500 m positive vertical motion (e-01 m/s) for increasing values of lake surface temperature. The considerable convective activity over eastern Lake Erie for the +20K case is due to the greatly enhanced instability associated with the increase in air temperature over the lake.
