Like most other psychiatric illnesses and health conditions, a combination of several different factors may increase the likelihood that a person will experience an eating disorder at some point in their life.
Waterspout. A waterspout is an intense columnar vortex that occurs over a body of water, connected to a cumuliform cloud. In the common form, it is a non-supercell tornado over water. While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur.
A tornado which travels from land to a body of water would also be considered a tornadic waterspout. Since the vast majority of mesocyclonic thunderstorms occur in land-locked areas of the United States, true tornadic waterspouts are correspondingly rarer than their fair-weather counterparts in that country.
