Hurricanes and solar power sats
Okay, it's fairly off-the-wall... but who knows?:
http://www.sciam.com/article.cfm?art...7F83414B7F0000 Basically, you use the microwaves from the solar power satellite to heat the air and change its track. From page 5: "Who Can Stop the Rain? If it is true, as our results suggest, that small changes in the temperature in and around a hurricane can shift its path in a predictable direction or slow its winds, the question becomes, How can such perturbations be achieved? No one, of course, can alter the temperature throughout something as large as a hurricane instantaneously. It might be possible, however, to heat the air around a hurricane and thus adjust the temperature over time. Our team plans to conduct experiments in which we will calculate the precise pattern and strength of atmospheric heating needed to moderate hurricane intensity or alter its track. Undoubtedly, the energy required to do so would be huge, but an array of earth-orbiting solar power stations could eventually be used to supply sufficient energy. These power-generating satellites might use giant mirrors to focus sunlight on solar cells and then beam the collected energy down to microwave receivers on the ground. Current designs for space solar power stations would radiate microwaves at frequencies that pass through the atmosphere without heating it, so as to not waste energy. For weather control, however, tuning the microwave downlink to frequencies better absorbed by water vapor could heat different levels in the atmosphere as desired. Because raindrops strongly absorb microwaves, parts of the hurricane inside and beneath rain clouds would be shielded and so could not be heated in this way. In our previous experiments, 4DVAR determined large temperature changes just where microwave heating could not work, so we ran an experiment in which we forced the temperature in the center of the hurricane to remain constant during our calculation of the optimal perturbations. The final results resembled those of the original, but to compensate for making no initial temperature changes in the storm center the remaining temperature changes had to be larger. Notably, temperature changes developed rapidly near the storm center during the simulation." So instead of hitting Florida and then turning north to hit New Orleans, Katrina goes somewhere else...say it goes to Cuba, then hangs a left and heads for Venezuela. .....in fact, say _all_ future Atlantic tropical storms go to Cuba, and then hang a left and go to Venezuela....until those commie miscreants learn who their true friends are, and embrace the wonders of capitalism! By God, now that's the ticket! ;-) Pat |

From page 5: Sure. Given functional multiple gigawatt SPS. Differential heating of water across the track also sounds possibly interesting. Course, the obvious flipside is to generate storms. |

"Large amounts" and "quickly" are the ONLY way we have of generating fusion power effectively. The amounts are measured in megatons of TNT and quickly is measured in milliseconds. - Bill Frensley |

I think you're talking about the amusingly common suggestion of nuking the eye to try to dissipate the hurricane. What happens in the models of that situations is merely that you end up with a mildly radioactive hurricane. The extra updraft is sometimes considered, but the burst of heat is apparently too brief to have lasting results. However, that's not what Hop David asked about. The scenario under immediate consideration was vaporizing a large city in the path of the hurricane in an attempt to deflect it. |

Here, Hugo Gernsback talks up the idea of going after them with Napalm-Magnesium bombs: http://www.twd.net/ird/forecast/1955hurricane.html Remember...WE MUST ACT SOON, AT THE STORM'S BIRTH! If we had taken Gernsback's advice and dropped NAPALM-MAGNESIUM BOMBS on all of Western Africa, it would KILL ALL THE BUTTERFLIES THAT LIVE THERE! With no butterflies living in Western Africa, there would be NO FLAPPING BUTTERFLY WINGS IN WESTERN AFRICA... and since butterflies flapping their wings in WESTERN AFRICA is what CAUSES HURRICANES, we would have NO MORE HURRICANES! There is also a sure-fire way to prevent terrorists from flying aircraft into skyscrapers. WE MUST BUILD THE SKYSCRAPERS UNDERGROUND! They can have HUNDREDS OF FLOORS, but GOING DOWNWARDS, not UPWARDS! All that will be visible on the EARTH'S SURFACE will be a large cap of ARMOR PLATE with a NUCLEAR SKY-SWEEPER ANTIAIRCRAFT GUN ON IT! A Nuclear Skysweeper firing PLUTONIUM-RADIUM-URANIUM-NAPALM-MAGNESIUM SHELLS! Mosquitos are a problem...but if we were to DETONATE DDT-NAPALM-MAGNESIUM HAND GRENADES in ALL STANDING RAIN PUDDLES after every storm, they would be QUICKLY ELIMINATED. IT IS THEN WE MUST ATTACK! :-) Pat |

IIRC, you dropped the H-bomb into the hurricane at a good distance from the eye, and created a second cyclic turbulence with the heat generated by the thermonuclear blast. The two competing vortices were supposed to cancel each other out, and make the storm fall apart. Pat |
