Integrated Kinetic Energy
This calculator will let you estimate the IKE and Surge Destructive Potential based on estimates of the outermost extent of tropical storm (TS), 50 kt, and Hurricane Force (H) winds in each storm quadrant. The results will give you ball park estimates if you use the operational wind radii. These estimates are based on some very coarse wind field assumptions. An improved estimate would come from a gridded wind analysis or model input data using the methods described in Powell and Reinhold 2007.
Update: Please note that IKE calculations prior to October 23, 2012 used a surface air density 0f 1.0 Kg per cubic meter. Current calculations (after October 23, 2012) use a more representative value of 1.15 kg/cubic meter based on GPS sonde measurements in hurricanes.
