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 ... WebThe direction of geostrophic flow is parallel to the isobars, with the high pressure to the right of the flow in the Northern Hemisphere, and the high pressure to the left in the …

Webwinds are called subgeostrophic. So the Rossby Waves produce acceler-ation around the ridge in the jet stream (supergeostrophic flow) and deceler-ation around the trough, (subgeostrophic flow) . Like traffic on the motorway, fast-moving air ‘piles up’ into the back of the slow-moving air, creating congestion or convergence
