Numerical simulation of transitions in boundary layer convective structures in a lake-effect snow event

The magnitude of the lake-air temperature difference, wind velocity and shear, capping inversion height and strength, upwind stability, lake temperature distribution, and latent heat release all influence the magnitude of the event (Braham and Kelly 1982; Hjelmfelt 1990; Kristovich and Laird 1998)....

Description
Summary:The magnitude of the lake-air temperature difference, wind velocity and shear, capping inversion height and strength, upwind stability, lake temperature distribution, and latent heat release all influence the magnitude of the event (Braham and Kelly 1982; Hjelmfelt 1990; Kristovich and Laird 1998). For smaller values of the Obukhov length, thermal instability (heat flux) is of greater importance. [...]rolls might be expected for bigger values of the Obukhov length, and cells for lesser values (e.g., Grossman 1982; Atkinson and Zhang 1996).
