"Controlling Hurricanes" ...is hard....

After simulating a hurricane that occurred in the past, we can then change one or more of its characteristics at any given time and examine the effects of these perturbations. It turns out that most such alterations simple die out. Only interventions with special characteristics--a particular pattern or structure that induces self-reinforcement--will develop sufficiently to have a major effect on a storm.
