They use a unit of measure to define how much water is in a cloud/
thunderstorm/hurricane. *At one point they use elephants/second to
describe the inflow of moisture in a thunderstorm. *Quite funny.


Given something of the order of one gram of water per cubic meter of
cloud in a decent cunim and a smallish storm cell about a kilometer
cube, then you've got around a million kilograms of water - or
somewhere about a thousand tons in American units. I use the same
argument as the NPR clip, only I measure the lift in gliders -
assuming they're 1,000 pounds each - so a small cumulonimbus weighs as
much as 2,000 gliders. Plenty of lift to go around!
