Add a bigstorm scenario from David Culp

<?xml version="1.0"?>
<!-- Notes:
David Culp: 1) The AIStorm sets the properties: /environment/turbulence/magnitude-norm /environment/turbulence/rate-hz The actual turbulence effects are handled by the FDM. If the effects are deemed unrealistic, then that will have to be fixed in the FDM(s). 2) The zone of turbulence is cylindrical, and is centered at the AIStorm's lat/lon. The diameter is set with <diameter-ft>, the top with <height-msl>, the bottom is assumed to be at <altitude> minus 1000 feet. 3) Note that the zone of turbulence may not match well with the visual model of the storm. In this case I had to x-offset the storm model by 4700 meters to match the zone of turbulence. (i.e. the storm model is 4700m off center). 4) While I was in there I also increased the speed of the lightning flashes to look more realistic.

This scenario puts a thunderstorm with lightning and
turbulence over San Francisco at 5000 feet MSL. The
"bottom" of the thunderstorm is at 5000 feet, with parts
extending above and rain below it. The storm is moving on
a true heading of 100 degrees, at a ground speed of 25 knots.
The AI thunderstorm contains a cylindrical zone of turbulence,
with a diameter set by <diameter-ft>, a top set by <height-msl>,
a bottom equal to <altitude> minus 1000 feet, and a strength
set by <strength-norm>. It does not interact with terrain.
