WebSUBGEOSTROPHIC AND SUPERGEOSTROPHIC WIND The information in this lesson is an extension of the previous lesson on the “Gradient Wind”. A gradient flow through a trough is termed “subgeostrophic”. The “sub” means the wind speed is less than what would be expected if the wind was geostrophic. In the first example below ... WebTherefore, it is likely that occurrences of LLJ maxima with subgeostrophic wind speeds are related to a different mechanism. The existence of inertial oscillations implies that the wind dir- ection changes near the ground due to the action of friction.
