Methods and apparatus for affecting atmospheric cyclones and quantifying parameters related to affected cyclones are disclosed. These methods and apparatus involve attacking a cyclone chemically, without the use of explosives, with an energy transfer inhibitor that can interfere with the transmission of energy from the sea surface to the cyclone. The energy transfer inhibitor, if properly chosen and placed in a desired path of the storm, can deny one part of the storm energy from the latent heat of vaporization of water, thereby creating an imbalance in the centrifugal force of the cyclone. The imbalance can reduce the intensity of the cyclone and can be used to steer the storm. Quantifying parameters associated with an affected cyclone enables forecasting the cyclones energy state, path, intensity, or other related parameters and evaluating possible additional energy transfer inhibitor distribution.
