Motion and structure of atmospheric mesoscale baroclinic vortices: dry air and weak environmental shear

Päschke, Eileen ; Marschalik, Patrik ; Owinoh, Antony Z. ; Klein, Rupert (2012)

A strongly tilted, nearly axisymmetric vortex in dry air with asymmetric diabatic heating is analysed here by matched asymptotic expansions. The vortex is in gradient wind balance, with vortex Rossby numbers of order unity, and embedded in a quasigeostrophic (QG) background wind with weak vertical shear. With wind speeds of 60–120 km h-1, such vortices correspond to tropical storms or nascent h...
