Any suggestions for a student the wants to do a science fair project on
meteorology? Her idea is to look at the relationship between humidity
in the air and tornadic activity. I was afraid of it being a glorified
tornado chamber project. :) She is a high school senior who is very
intelligent. Any suggestions would be greatly appreciated.

Thinking out loud....
An important consequence of the air mass's humidity is its
adiabatic lapse rate, that is the cooling which it experiences when rising.
You will be familiar with the interaction of lapse rate with the actual
temperature gradient so as to induce vertical instability.
It would be rather nice to demonstrate this effect.
It would be necessary to use model materials.
I have in mind a liquid column with a controlled vertical temp gradient,
and some sort of air mass standin - perhaps a tied balloon with carefully
chosen contents, so that the balloon rises or does not, depending on the
thermocline.

....just a thought...
