Data and analysis for tropical cyclone track forecast errors using PPVI

This repository contains the following:Piecewise Potential Vorticity Inversion (PPVI) codePost-processed analyzed filesPlotting scriptsFiguresThe original PPVI code was provided by Professor Chun-Chieh Wu's group at National Taiwan University which was used in the publicationWu, C., T.
