North Atlantic and Northeast Pacific Tropical Cyclone Intensity Comparison Using Integrated Kinetic Energy
The Integrated Kinetic Energy (IKE) of tropical cyclones (TCs) in the Northeast Pacific (NEP) basin is computed from the Extended Best Track Dataset from 2004-2013. Analysis of extreme terciles is conducted based on the IKE values of the TCs and compared with those of the North Atlantic (AL) basin....
