Tuning VIPER 2.0
Baseline
To start the tuning exercise, we identified cases data
that simultaneously have low background turbulence, low stratification, and
low crosswind shear gradient. None of the user-adjustable model constants
should have an effect on these cases. Thus we are looking at the (hard-coded)
baseline behavior for these cases.
Baseline Results Using The Denver 03 Data
Effect of strong ambient turbulence
Next we identified cases from the data that simultaneously have
low stratification, and low crosswind shear gradient, but high ambient
turbulence. These cases are used to ajdust the edr* dependence on the model
entrainment coefficients.
Strong Turbulence Results using
the Denver 03 Data
Effect of moderate ambient turbulence
Next we identified cases from the data that simultaneously have
low stratification, and low crosswind shear gradient, but moderate ambient
turbulence. These cases are used to ajdust the edr* dependence on the model
entrainment coefficients.
