Comparison of observations with idealized model results for a method to resolve winter lake-effect mesoscale morphology

Forecasters in the Great Lakes region have for several decades recognized a general relationship of wind speed and overlake fetch to lake-effect snowstorm morphology. Laird and Kristovich provide an assessment of U/L criteria using observational datasets. Results show that the quantity of U/L contai...

Description
Summary:Forecasters in the Great Lakes region have for several decades recognized a general relationship of wind speed and overlake fetch to lake-effect snowstorm morphology. Laird and Kristovich provide an assessment of U/L criteria using observational datasets. Results show that the quantity of U/L contains important information on the different mesoscale lake-effect morphologies and provides only a limited benefit when being used to predict mesoscale morphology in real lake-effect situations.
