Method for preventing a formation of, and/or for dispersing, a tropical cyclone, and arrangement therefor

A method for preventing a formation of a hurricane storm and/or dispersing a tropical cyclone storm, the storm defining an eye and the method comprising the steps of:

• providing at least first and second vessels configured to be pressure resistant, spherical and sinkable with said first vessel having a first sinking velocity V1 and said second vessel having a second sinking velocity V2 lower than said first sinking velocity V1;
• filling said first and second vessels with a refrigerant;
• loading said first and second vessels into at least one aircraft;
• positioning said at least one aircraft over the eye of the storm and/or in direct proximity of said storm;
• dropping said first and second vessels loaded with said refrigerant directly whereat the eye of said storm is located and/or in direct proximity of said storm so as to permit said first vessel and said second vessel to plunge into water lying under said storm and/or so as to permit said first vessel and said second vessel to plunge into water in direct proximity of said storm;
• and,
• opening said first and second vessels and releasing said refrigerant at a predefined depth in the water wherein a depth of opening of said first vessel is greater than a depth of opening of said second vessel.
