Iterative refinement and smoothing of cyclone tracks from mean sea level pressure data

Local nonlinear regression fits are applied to mean sea level pressure data from $24$ member ensemble forecasts of three recent tropical cyclones in the Australian region. Cyclone track estimates derived from the fits are subjected to verification calculations in the form of error-spread diagrams, demonstrating consistency with a recent global ensemble study, with attention also given to cross and along track error components.
