I know, I know, I said I would quit, but I have so many tests and so much free time after, so I thought I'd make one last project. Supercells are tornadic rotating thunderstorms that are very powerful; they are the primary creators of tornadoes. I know this isn't the general shape of a textbook supercell, and it lacks the typical hook shape, but I'm not smart enough to randomly generate supercells in their usual form.
This is just a random storm generator that tornadoes can spawn in. CAPE (Convective Available Potential Energy) is instability in the air, or the probability that a thunderstorm will fire. SRH (Storm Relative Helicity) is a measure of the potential for cyclonic updraft rotation in right-moving supercells, and is calculated for the lowest 1-km and 3-km layers above ground level.
