Surface Divergence

The following four panels show the 2000 UTC (1500 LST) 10 m surface divergence (e-05 / sec) for increasing values of lake surface temperature. Note that for the +20K case, remaining areas of weak convergence and divergence (aside from the activity over eastern Lake Erie and along the top of the domain) are due to changes in surface roughness and elevation.
