Equivalent-Barotropic Atmosphere Constant-pressure surface now hasisotherms on it everywhere parallelto the contours Wind can change speed with heightbut not direction Systems are vertically stacked, notemp advection exists Equivalent-barotropic levelpresumed to be near at 500 mb Atmosphere often close enough tothe equivalent-baroclinic state (i.e.tropics) such that barotropicdynamics may be dominant
Baroclinic Atmosphere No assumptions about thepatterns of density ortemperature on a pressuresurface Thermal wind can now changespeed and direction Systems slope with height Real atmosphere alwaysbaroclinic
