AM transport (a and b) and adiabatic heating (c and d) associated with stationary waves in the Venus PCM. Panels a and b: EP flux and the vertical flux of AM (arrows; both divided by basic air density), along with the corresponding zonal wind acceleration (color shading). Panels c and d: Adiabatic heating induced by stationary waves and the associated vertical heat flux component. Light and dark gray shading indicates, respectively, the maximum and mean surface topography at each latitude. Black contours represent the background zonal wind (m/s).
