VVP (Velocity Volume Processing) Provides an estimate of the wind profile up to a certain height HWind (Horizontal Wind) Shows wind flow at a specific altitude. PPI (Plan Position Indicator) Gives representation of the cloud echoes in a horizontal plane. MAX (Maximum) Shows a 2-dimensional (2D) flow for the horizontal and vertical profile of the clouds. EHT (Echo Height Top) Gives a representation of the height to which the top of the clouds extend.
