Why does the wind drop in the centre of a Hurricane?


At the centre of a hurricane the pressure is a minimum, so there is no
pressure *gradient*, i.e. the pressure does not vary with distance. Because
the wind is caused by the pressure gradient, there is little or no wind in the
eye of the hurricane. The pressure gradient is a maximum just outside the eye
wall, where the strongest winds are.
