Default New definition of thermal strength

From NPR's science guy: http://www.npr.org/blogs/krulwich/20...eighs-how-much

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!

I heard this live yesterday. Being a Python fan I had to wonder if
they were Asian elephants or African elephants. The whole concept is
a bit hard to swallow.

Yep, especially since H2O in its vapor state is a lifting gas. The
more water vapor in the air, the lighter it is. http://en.wikipedia.org/wiki/Water_vapor

Yes, but water vapor is invisible. If you can see a cloud, it has
liquid water or ice particles.

Is that an African swallow or a European swallow?
Bloody weather!
