Discussion
Around a northern hemisphere high the gradient wind is _____ than the geostrophic wind.
Answer: B
Around a high the pressure gradient and centrifugal forces both act outward while only the Coriolis force acts inward, so a larger wind is required to achieve balance and the flow is supergeostrophic. The centrifugal force always acts outward, which is what the second option gets wrong. The effect is present at any radius, growing as the curvature tightens, until the anticyclonic limit is reached.
