Torque a huricane?

  1. Nov 9, 2007 #1
    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?

    The answer to the first question in this article, http://www.usatoday.com/weather/resources/askjack/wfaqhurm.htm, pretty much sums things up:

    As with most hurricane modification ideas, this one is much easier said than done.

    Note that the article does address project STORMFURY, which more-or-less attempted to do what you suggested back in the 1960s.

    Naturally occurring concentric eyewall formation seemed to be the dilemma. That is, a ring of thunderclouds stealing moisture from the eyewall lead to dissipation of the inner eyewall; but a concentric eyewall can form further out, which initially might have a lower angular velocity, but then intensifies. So seeding was emulating such naturally occurring phenomanon. http://www.aoml.noaa.gov/hrd/tcfaq/D8.html
    Hurricanes contain immense energy. So to attempt the original idea of pollution added or enormous seeding on a hemi-hurricane scale, might seem too difficult; or is more experimentation worth considering in diverting such enormous heat engines?

    [related subject] One of the best explanation that i have seen for tonadoes is using a natural charged sheath vortex, first proposed by scientist Peter Thompson. His description is hard to fault; http://www.peter-thomson.co.uk/tornado/fusion/Charge_sheath_vortex_basics_for_tornado.html

    He then goes on to consider some basic physics, often overlooked because they sit on adjoining fields of research.

    I feel that currently this is by far the best explanation for tonadoes that i have seen anywhere. He gives an explanation for the origin of tornadoes, their basic observed properties and how they disspipate. So far theories that address all of those properties in simple concepts have been hard to find, but theres a couple of good ones out there now. Many theories explain certain specific aspects of tornadoes, but they do not explain them in their entirety like he seems to have done.
