"Wish our military had the technology to knock these storms into oblivion"
I had been thinking about controlling hurricans myself and even thought of dry-ice. Darn if it wasn't tried before.
Early Attempts to Control Hurricanes:
Prior to the work done in the area of storm modification by the South Florida company Dyn-O-Mat, there had not been any attempts to modify hurricanes since 1980, when the NOAA decided to end Project Stormfury.
However, for a period of over 30 years, scientists attempted to find a solution to the hurricane problem through storm modification. Early projects included one led by Dr. Irving Langmuir and a group of scientists at General Electric. The project, called Project Cirrus, focused on seeding hurricanes with dry ice.
Despite some apparent success with the project, not a lot of research done until after the stormy years of 1954 and 1955 when President Eisenhower appointed a special committee to look into storm modification. Overcoming a lack of enthusiasm and interest in the subject from some scientists, the program took off in the early 1960s with Project Stormfury, which was headed by Dr. Robert H. Simpson, director of the National Hurricane Research Labs.

Subsequent headline, "10,000 dead fish picked up by Hurricane and re-distributed into houses, schools at 150+ MPH. Massive loss of life reported."
there is Gas rationing
NO WAY only one 747 could carry all the shredded White Water documents.....
Perhaps he is going to drop 100 Tons of Gas-X in the hope that Ivan will "Break wind"
And when he's done there he's going after a volcano with a fire extinguisher.
I wonder what would happen if they dumped concrete mix instead... heh...
Yes, he must be...
See my post #61.
They actually had some success in dropping the intensity of a couple storms.
Oh no....the chemtrail people will go beserk....
Evergreen Aviation is 'allegedly' a 'CIA front' and responsible for the spraying of magic chemtrails....across America....uh oh....
Lettuce spray this is not happening...

The Air Force Reserve's 'Hurricane Hunter' squadron flies right through huge, nasty hurricanes all the time- often multiple passes in a single mission. I went to their web page wondering how they keep their planes from being damaged doing that.
It was a FAQ question there. They pointed out that airplanes are made to deal with hundreds of mile per hour winds. Bad if it happens when they're on the ground, but they're built to handle it. They did not mention any special structural reinforcement for their Herks, that I recall.

These guys do it all the time, but not using a 747
Hey Bubba, watch what I can do!!!.....ALERT
instant sandstorm?

Subject: C5d) Why don't we try to destroy tropical cyclones by adding a water absorbing substance ?
"Dyn-O-Gel" is a special powder (produced by Dyn-O-Mat) that absorbs large amounts of moisture and then becomes a gooey gel. It has been proposed to drop large amounts of the substance into the clouds of a hurricane to dissipate some of the clouds thus helping to weaken or destroy the hurricane.
At HRD we tried the one possible way that "Dyn-O-Gel" could weaken a hurricane in the MM5 numerical model. We saw an effect but it was small (~1 m/s). The argument was that the glop would make raindrops lumpy (i. e., non-aerodynamic) they would fall slower and increase condensate loading, thus weakening the eyewall updraft. If, by contrast, one increases the fall speed of the hydrometeors, the storm strengthens (again by only ~1 m/s). In the numerical experiments "decrease" meant reduce the fall velocity to half the real value, and "increase" meant double the real value. The foregoing effect is larger than anything one could hope to produce in the real atmosphere.
The observation that the experiment that "Dyn-O-Gel" conducted actually "dissipated" clouds is problematic. Did they watch any unmodified clouds ? Isolated Florida cumuli have short lifetimes, and these are just the ones an experimenter would logically pick.
Accepting for the sake of argument that they actually did have an effect, the descriptions seem more consistent with an increase in hydrometeor fall speed and accelerated collision coalescence, which the numerical model results argue would strengthen the hurricane, but not much. If this speculation proves to be correct, "Dyn-O-Gel" might be useful for rainmaking during a dry spell, unlike glaciogenic seeding which (in the tropics at least) tends to make rainy days even more rainy--if it does anything at all.
One of the biggest problems is, however, that it would take a LOT of the stuff to even hope to have an impact. 2 cm of rain falling over 1 square kilometer of surface deposits 20,000 metric tons of water. At the 2000-to-one ratio that the "Dyn-O-Gel" folks advertise, each square km would require 10 tons of goop. If we take the eye to be 20 km in diameter surrounded by a 20km thick eyewall, that's 3,769.91 square kilometers, requiring 37,699.1 tons of "Dyn-O-Gel". A C-5A heavy-lift transport airplane can carry a 100 ton payload. So that treating the eyewall would require 377 sorties. A typical average reflectivity in the eyewall is about 40 dB(Z), which works out to 1.3 cm/hr rain rate. Thus to keep the eyewall doped up, you'd need to deliver this much "Dyn-O-Gel" every hour-and-a-half or so. If you crank the reflectivity up to 43 dB(Z) you need to do it every hour. (If the eyewall is only 10 km thick, you can get by with 157 sorties every hour-and-a-half at the lower reflectivity.)
Silly?? Are you kidding? Anything that involves explosions and hurricanes......TOO cool! I'd pop corn for that one.........who cares if it works............
