Is there any data on how much the formation of an eye will affect the course of a storm? The eye's an area of high(er) barometric pressure smack dab in the middle of a hurricane, I'd imagine that would affect the steering properties somehow. Insight?
Actually, the eye is the lowest pressure... since winds blow from high pressure to low pressure, and are deflected because of the Coriolis force, they blow inward and counterclockwise. They eye is essentially the point that the winds rotate around. The lower level winds converge around the eye. Now, nature abhors a vacuum, so if there were no upper level divergence, or outflow, then the pressure would increase and weaken the storm.
