Re: [PLUG] Waaaaay Off Topic: Thunderstorm Movement

The full answer to your question might fill a book, and sometimes it has;
I recommend "Severe Convective Storms and Tornadoes: Observations and
Dynamics" by Howard B. Bluestein.  Warning: you will need an understanding
of partial differential equations and some prior acquaintance with fluid
mechanics and thermodynamics would also be useful.

The short answer is that it's the storm that's moving.

Hurricanes are fueled by water vapor which in turn comes from warm
ocean water, i.e., they're continuously ingesting more moisture.
There's a very good explanation of their formation here:
