E++99 writes "In the wake of Katrina, two teams of climate scientists have been working to steer hurricanes. Both teams are using the technique of removing power and speed from strategic points in the hurricane, effectively refracting its path. The American team is approaching this by warming the areas of the tops of the hurricane clouds, either by dropping ash to absorb heat from the sun, or directly beaming microwaves on those areas from space. The Israeli team is taking the approach of cooling the bottom of the hurricane by releasing dust along its base."

I'd imagine controlling a viciously-strong storm up the coast could have some devastating consequences. Sure, it wouldn't hit the intended target at full force but if an enemy controlled enough of them during a bad hurricane season they'd wear down the area a little.

It seems to be working; I haven't seen or heard about hail damage in a few years now.
There is a lot of energy in a thunderstorm... not hurricane energy, but I expect such a thing IS doable.

One day the coup was wiped out by one of the rare hurricanes up here. Specifically the one in the Fergus/Guelph corridor.
He didn't think much of it other than "dammit".
Not long after he got a visit by a bunch of government types (he never said who, but said he was scared from the moment they said "hello".
They explained to him the hurricane was tracking a straight line then took a 10 mile south diversion, wiped out his coup then went back to it's original course. They wanted to know what on earth he had in that coup.
He said "hey, if I could divert the course of a hurricane would I me messing around with chickens?" and they want away.

Later that evening, we were driving around searching for food. We found a KFC open about 30 miles away, but there was a line halfway down the block -- apparently everyone else was doing the same. My dad decided we would just go to the 7-11 across the street instead. I got a hot dog, some milk, and some candy, and my dad got a couple of sodas and some nachos. Back in the car, I offered him some of my candy. "These things are amazing," I said, "You've got to try them!" He poured some Pop Rocks in his mouth, and washed them down with a swig of Pepsi. Almost immediately, he started crying out in pain. My mom rushed him to the nearest hospital, almost 20 minutes away. Fortunately, we got there in time, and the doctors successfully operated on his distended and ruptured stomach. Over the next few days, many well-wishers showed up, one of whom had found our family cat, Patches. The nurses made a special exception, and allowed the cat to sleep in the bed with my old man, who I imagine was rather depressed in light of recent events, though he never showed it. Unfortunately, that cat was NOT Patches, as we later learned, only too late. The next morning, we found my old man cold and still in his bed. The cat had eaten his soul.

If you steer the hurricane away from the big city, but it still hits a small town 100 miles away, and kills 100 people, have you just murdered those 100 people? And at that rate, the ones who survived are going to be pretty pissed that the government shot a HURRICANE at them.
What if we screw up, and send a Category 5 Hurricane on a collision course with Havana or Mexico City? That would have disastrous consequences.
This sort of technology has terrifying military applications as well. Send a hurricane at *insert insular communist dictatorship here*, wait til it's passed, and then invade the nation while they're picking up the pieces.
I'm generally for the advancement of science, but in this case, we're coming a bit too close to "playing God" for our own good.

A typical hurricane packs a punch worth an "ordinary" atomic bomb exploding every minute. It would take an insane amount of energy to add/remove to even make a statistically significant difference.
Mother nature is *really* powerful and not to be messed with!
Ah, now if they could figure out how to remove some energy and convert into electricity, now THAT would be useful... a season's worth of storms can solve whole world's energy problem
Re:Might be just a scam! (Score:5, Informative)
Cyclones have insane energy levels, true, but they are still storms and winds, and they obey natural laws. One of these laws says that they drift based on pressure differentials in the surrounding area - ie, if the air pressure is higher to the north than the south, the cyclone will head south.
Air pressure is related to temperature; hot air rises, which will make the air pressure go down, while cold air sinks, making the air pressure go up (*warning: highly simplified explanation!*).
Besides, this technique is what already causes cyclones to break up - when they hit land, the temperature grade becomes very uneven, because land absorbs heat differently to water. This creates an asymmetrical bulge or dip in the cyclone - which is bad for what is basically a rotating disk of air. This asymmetry forces the cyclone to rip itself apart - usually by sending storm systems deep inland. Nor does it take a huge difference to do this - cyclones are chaotic, unstable systems: science speak for saying that a small push can send it into a different state.
For an easy analogy - imagine a motor biker rider. The motor bike, going at 100MPH, has insane amounts of kinetic energy, compared to what the rider could normally attain. But the bike is an unstable system - a small nudge of energy (rider shifting balance, for example) can make the bike change direction. Of course, get this wrong, and disaster strikes - too much energy causes the bike to fall over.

Pointing out something that might go wrong does not require wit, only a desire to obstruct or to appear wise. Even less is required to point out that something vague and unspecified might go wrong. Even less, to refuse to notice that something massively valuable is likely to go right.

I am highly skeptical of any conclusions drawn from simulated data. As a cloud modeler running at very high resolutions (much higher than hurricane simulations since I am studying much smaller individual thunderstorms) I can tell you that even the most sophisticated cloud microphysics parameterizations are extremely crude. Clouds and rain are represented not by droplets, but mixing ratios, and gross assumptions are made about drop size distributions, transfer rates between species, etc. So, to say "we dropped some parameterized soot in the model and it made a difference" is not saying much.
Small perturbations in a highly unstable chaotic simulations such as a hurricane simulation will result in noticeable changes in the simulation days down the road. This is not a surprise. But even a small perturbation in a model would involve a huge amount of matter or energy in the real world, and whether these perturbations could be orchestrated to create a predictable change in course is very highly doubtful.
Another problem that plagues all forms of weather modifications is that you'll never know for sure if the modifications themselves caused a shift in storm evolution, or if an observed shift was something that would have happened anyway. Causality is the hardest thing to prove - even in a model where you know the state of your system to seven decimal points of precision.
I really hope federal money is not spent on this kind of research. Is there a limit to the hubris of mankind?

My point is that directing a hurricane else where will likely cause more damage and deaths because the places where hurricanes hit have developed "defenses" against them. This is not an useful idea if they're intending to do good. Plus a great deal of natural life actually depends on the occasional hurricane to replenish itself. Hurricanes are natural events in those areas and people and wildlife have adapted to them.
