To have harmful wind speeds, a hurricane needs to have lots of angular momentum. If some of the angular momentum could be dispersed to farther from the center of the storm, wind speeds would be lower. If I understand it right, a hurricane has air coming in from the periphery at low altitude,

A few random thoughts on this very long thread. 1) Steering Could you steer a hurricane by cooling one side and heating another - kinda like how a tank steers by slowing down one track. Done early enough, even a small change in angle would adjust the landfall by miles. 2) Suppression The idea of

While it is quite probable that hurricanes result in radiation escaping to space more easily, the short term local effect, I believe, is to suppress outgoing longwave radiation (OLR): Positive values of OLR are indicative of suppressed convection, while negative values suggest enhanced convective
