"a bold red "l" has already been marked on the map in the great lakes area near green bay to denote the general center of low pressure in that area. compare the hand-twist model of a low to the wind directions at stations in the several-state area surrounding the low-pressure center. wind directions at these stations suggest that, as seen from above, the air spiraled generally around this northern hemisphere low-pressure center."

Wind directions at these stations suggest that, as seen from above, the air spiraled generally around this northern hemisphere low-pressure center. The answer is counter clockwise. In the Northern Hemisphere, the wind in a high pressure system flows in clockwise direction out of the center, while in low pressure system wind flows in a counterclockwise direction towards the center.
