What conditions lead to supergeostrophic and subgeostrophic flows?
What will be an ideal response?
Answer: Troughs and ridges. As air approaches a ridge it must begin turning to the right in order to remain parallel to the pressure gradient. For this to happen the Coriolis force must increase, which means the speed must increase. In other words, the wind speed must exceed what is given by geostrophic balance. Conversely, air flowing around the trough must slow down so that it can turn to the left. The Coriolis force is still present and pushing to the right of the wind direction, but it is weaker than the pressure gradient force and thus the wind can divert from a straight geostrophic path.
