Subgeostrophic flow
WebAgeostrophic flow is clearly evident in the bottom kilometer or so of the atmosphere where the frictional drag of the rough underlying surface is di- rectly felt by the flow. For … 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

In atmospheric science, geostrophic flow is the theoretical wind that would result from an exact balance between the Coriolis force and the pressure gradient force. This condition is called geostrophic equilibrium or geostrophic balance (also known as geostrophy). The geostrophic wind is directed parallel to isobars (lines of constant pressure at a given height). This balance seldom holds exactly in nature. The true wind almost always differs from the geostrophic wind due to ot… WebThe geostrophic wind is the wind flow that occurs in the middle latitudes aloft in the troposphere. The winds have a more difficult time obtaining geostrophic balance in the …
WebA 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 (“subgeostrophic wind”), the wind is flowing through a trough. Browse through forecasting techniques, weather forecasting short essays and all …
