A Derivation of the power Dissipation Index Using Peak Virtual Power

It is shown that the physical damage resulting from severe weather phenomenon such as hurricanes and tornadoes encapsulated in various scales such as Saffir-Simpson, TORRO and the Enhanced Fujita Scale, and measured by the Power Dissipation Index can be predicted using the concept of the Peak Virtual Power. This corresponds to the maximum rate of Entropy production, which is considered to be the basic physical principle underlying the damage.
