A intensity prediction scheme of tropical cyclones (TCs) based on the energetially based dynamical system  (EBDS) for the western North Pacific (WNP) has been developed using the machine learning method called Long Short-Term Memory (LSTM). In the EBDS, a dynamical efficiency is introduced to the intensification potential of a TC system. The dynamical efficiency E (0 ≤ E ≤ 1) reflects the effective conversion of potential energy production to kinetic energy production for the TC system.     Read the article >>
