Might one torque a huricane? That is alter the orthogonal angular momentum vector? In other words, cause a hurricane to wobble, LIKE a figure skater initiating spinning, and then pulling in just one arm; hence wobbling. Huricanes have sort of linear motion of slow 10-15 mph. Such tight low pressure heat engines of course get their fuel from endothermic vaporation of warm sea water fuel. Then up the chimney, and condensation to form water droplets initially and eventually in part to rain, an exothermic process. The resultant energy and differential cooling can result in internal winds. So could one run milatary plane engines slow and dirty, releasing as much pollution or silver iodine as possible for over about 200 miles on one side of huricane only. So more condensation and rain, and thus more energy released for wind creation. So increasing the angular velocity, and decreasing the moment of inertia - moreso on one side, even though there is a redistribution of energy. That is, more tight coiling on one side. This would have to be done persistently, in order not to miss a quanitative effect. Of course this would only be for a huricane headed directly towards 1 of 2 large populatec sites i.e. Houston or N Orleans. A viable experiment?
