  where p is the density of air, u is a sustained surface wind speed value, and dv is the volume element.
Extratropical cyclones can also be dangerous when their low-pressure centers cause powerful winds and high seas.A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form in a wide band of latitudes, from the equator to 50°. Although subtropical storms rarely have hurricane-force winds, they may become tropical in nature as their cores warm. See also
