Radar observations of misovortices within multiple long-lake-axis-parallel lake-effect bands during the OWLeS project
… to secondary circulations within these bands. Horizontal shear along these convergence zones yields vortex sheets that can break into discrete misovortices, likely through horizontal shearing instability (HSI). These misovortices then can strengthen or be maintained via stretching by the band …

Observations of misovortices within the 7 January 2014 Long Lake-Axis-Parallel lake-effect snow band during the Ontario Winter Lake-effect Systems Project
… convergence boundaries associated with cyclonic horizontal shear zones that likely originate from solenoidally-forced secondary circulations within these warm-core bands. In most cases, the shear zone is co-located with a sharp horizontal gradient in radar reflectivity, which corresponds to the …
