The waters of the Gulf are about 25°C. The cloud tops of Rita are
about -70°C to -80°C. That is about 100 degrees difference in a
distance of about 12 kilometers. Each change of one degree C to a CC of
water, one gram of water, is one calorie. If we knew how much water was
being lifted by Rita we could figure out how many calories of energy
there are in those waters.
We can figure out how much water is being lifted. The National
Hurricane Center is taking constant measurements.

Here's some raw data for figuring the math:

"... RITA IS MOVING TOWARD THE WEST NEAR 9 MPH ...15 KM/HR...AND THIS
GENERAL MOTION AT A SLIGHTLY FASTER FORWARD SPEED IS EXPECTED
DURING THE NEXT 24 HOURS.
MAXIMUM SUSTAINED WINDS ARE NEAR 175 MPH...280 KM/HR...WITH HIGHER
GUSTS. RITA IS A POTENTIALLY CATASTROPHIC CATEGORY FIVE HURRICANE ON
THE SAFFIR-SIMPSON SCALE. SOME FLUCTUATIONS IN INTENSITY ARE LIKELY
DURING THE NEXT 24 HOURS.
HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 70 MILES...110 KM...
FROM THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP
TO 185 MILES...295 KM. ..."
HEAVY RAINS ASSOCIATED WITH RITA ARE FORECAST TO BEGIN TO AFFECT THE
WESTERN AND CENTRAL GULF OF MEXICO COASTAL AREAS THURSDAY NIGHT
INTO FRIDAY. RITA IS EXPECTED TO PRODUCE TOTAL RAINFALL
ACCUMULATIONS OF 8 TO 12 INCHES WITH ISOLATED MAXIMUM AMOUNTS OF
15 INCHES OVER THE CENTRAL TO UPPER TEXAS COAST. ..."
>From this we can figure the speed covering a radius of the
hurricane-portion of the system.
9 mph forward motion, diameter of hurricane force winds is 140 miles,
it takes 15.5 hours to traverse one storm diameter. The rainfall in
that peak area is 8" to 12" up to peak of 15" maximum. Choosing the
lowest number 8" over 15.5 hours will give us some number we can use.
The area of a circle is Pi x R^2, = 15393.8 square miles.
8" of water = 20.32 cm.
15393.8 square miles = 398,697,600,000,000 sq. cm
398,697,600,000,000 sq. cm x 20.32 cm = 8,101,535,232,000,000,000 cubic
centimeters = calories.
That's how many calories it takes to raise those CCs by each degree.
8,101,535,232,000,000,000 = 9.422085e+012 kilowatt-hours
8,101,535,232,000,000,000 = 9.422085e+009 megawatt-hours
8,101,535,232,000,000,000 = 3.214949e+016 BTUs
8,101,535,232,000,000,000 = 3.391951e+013 megajoules
8,101,535,232,000,000,000 = 1.263522e+013 horspower-hours
This is not even counting the energy required to go from liquid phase
to gasous phase without any raise in temperature (600 cal per gram, per
CC).
You can multiply those numbers by about 700 (kilowatt-hours,
megawatt-hours, BTUs, megajoules, horsepower-hours) to see how much
heat is being extracted from the ocean and turned into death.
This is what Global Warming is ALL about. It takes storms of this
power, this often, to barely keep up with the heat going into the
system, trapped under greenhouse gases, during this part of summer.
OCTOBER is when the big storms hit, traditionally. This is just a
PREVIEW.
