New Metric to Measure Destructive Potential of Hurricanes

Current Hurricane Category numbers only count duration and intensity. Integrated Kinetic Energy (IKE) counts storm size too, which gives a better estimate of destructive potential.

Track Integrated Kinetic Energy (TIKE) accumulates the IKE over the cyclone season, for an objective measure of the Hurricane season.

Researchers at Florida State University have developed a new metric to measure seasonal Atlantic tropical cyclone activity that focuses on the size of storms in addition to the duration and intensity, a measure that may prove important when considering a hurricane's potential for death and destruction.

... Track Integrated Kinetic Energy (TIKE), builds on the concept of Integrated Kinetic Energy (IKE) developed in 2007 to more accurately measure the destructive potential of a storm. IKE involves using kinetic energy scales with the surface stress that forces storm surge and waves and the horizontal wind loads specified by the American Society of Civil Engineers. TIKE expands the concept by accumulating IKE over the lifespan of a tropical cyclone and over all named tropical cyclones in the hurricane season.

"TIKE gives a succinct picture by taking into account the number of tropical cyclones in the season, the duration of each tropical cyclone and the time history of the wind force over a large area surrounding each tropical cyclone. This makes TIKE much more reliable as an objective measure of the seasonal activity of the Atlantic hurricanes than existing metrics." [emphasis mine]
