The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury.
Height variations are the result of differences in temperature in the atmosphere. Lines of equal height are called contour lines (not isobars, as before on the surface map). On an upper level map, a ridge is an elongated area of high pressure and a trough is an elongated area of low pressure.
