The best I could find with some research was the Dvorak Technique used to measure cyclone intensity from visible and infrared images.

Also from Wikipedia:

While typical mature storms have eyes that are a few dozen miles across, rapidly intensifyingstorms can develop an extremely small, clear, and circular eye, sometimes referred to as a pinhole eye. Storms with pinhole eyes are prone to large fluctuations in intensity, and provide difficulties and frustrations for forecasters.[7]

Lastly I would guess it has to do with plain angular momentum. A cyclone that contracts will spin faster, if angular momentum is constant, in the same way that a figure skater speeds up when they tuck in their arms.
