WebWhat are supergeostrophic and subgeostrophic flow? Supergeostrophic flow is gradient flow found around high pressure systems where wind speeds are higher than expected given the pressure gradient force. Subgeostrophic flow is gradient flow around low pressure systems where wind speeds are slower than expected given the pressure gradient force. http://colaweb.gmu.edu/dev/clim301/lectures/wind/wind-grad
