I was an Amy Air Force Weather Observer & Forecaster for 5 years before, during, and after World War II. I've taught meteorology on the university level. And I've followed the subject all these years.A tornado over the ocean forms a waterspout, drawing ocean water upon into the "whirligig" of the storm. Over the years, I read of several accounts claiming that a waterspout has been broken up by canonshot.
In recent years, powerful laser beams have been generated for various purposes. I suggest that a laser beam might break up some tornadoes.
Sciemce supply houses, such as Edmund Scientific Supply, sell kits for creating "kitchen counter" tornadoes. And they sell small lasers for experimentation. This could be repeatedly worked with as Science fair Projects. (Warning! Wear protection for the eyes from laser beams!) Also, computer simulations can be set up for large scale cases.
If only it worked for some cases, it could reduce loss of property and possibly of lives.
If it worked, meteorolgists could experiment with "guiding" hurricanes by laser beams. (This could also be tested "on the counter".) This, if successful, would prevent hurricanes from skimming over areas where they could cause property damage and threats to human life.
