Summertime TABS model skill assessment

In summertime, the TGLO model does a much poorer job at predicting coastal sea-level. We attribute this primarily to fresh water run off from the Mississippi and other local rivers. Note how the time series diverges in late May, with the measured values higher than the simulated values. Also the simulated SSH seems to 'ring' too much, indicating that the drag in the model is too low, so that the coatally trapped waves are not damped out quickly enough. This seems to be a problem only for very strong storms (compare this figure to the late 2001 figure -- the variations here are much larger due to the magnitude of the blue northers that pass by).
