Simplified, the main driving force behind any wind is the horizontal

changes
in air pressure. The greater the difference, the stronger the wind. The
coriolis effect and the rotation of the earth make the wind blow
counterclockwise around a low pressure area, and clockwise around a high
pressure area (Northern Hemisphere).

A lower central pressure would mean a bigger pressure gradient, and
therefore stronger winds and a "more intense" storm. There is more to it,
but I tried to keep it simple.
