Question

Tornadoes form in unusually violent thunderstorms when there is sufficient (1) instability and (2) wind shear present in the lower atmosphere. Elaborate on what does instability mean when discussing the formation of a tornado?

A) dry air in the middle atmosphere being rapidly cooled by rain
B) winds at all levels of the atmosphere are strong and turn with height
C) an isolated strong thunderstorm just ahead of a squall line that merges with the squall line**********
D) very warm, humid conditions in the lower atmosphere; cooler than usual conditions in the upper atmosphere

Answer 1

Molecular mass of H2O is about 2+16 = 18 grams/mol
Molecular mass of N2 (80%of dry air) is about 28 grams/mol. O2 is about 32 grams/mol
In other words hot humid air is likely to have lower density than cold dry air.
If the light warm humid gas is under the heavy cold dry gas, you have a stability problem. If the warm wet stuff finds a route to rise through the heavy cold stuff, you get something like a chimney there. Whoosh !
