Tropical cyclone tracks

Introduction: Below are the tropical cyclone track datasets available for analysis. Tracks are based on the TRACK algorithm (see Hodges et al., 2017), with additional tracking with TempestExtremes. Data locations on JASMIN are given (monospace type). Additional datasets are available on other platforms (RACC, ECMWF, DKRZ), and these will be migrated to JASMIN as soon as possible. New datasets will be added as Huracán progresses. If you encounter any errors or broken paths, please inform Kevin Hodges, Pier Luigi Vidale or Alex Baker.

Data type: tropical cyclone tracks
Domain: Northern Hemisphere
Description: date, time, longitude and latitude over full cyclone lifecycles (precursor to post-tropical cyclone) as well as separate files containing pre-TC tracks, which are generated by TRACK prior to tropical cyclone identification
Variables: cyclone intensity metrics (vorticity, minimum sea-level pressure, and maximum wind speed at 925hPa and 10m) and cyclone-associated precipitation (or subset)

Version V03 has R34 data from the JTWC/NHC best tracks only. V10 will have more R34 data from CIRA and analysis of full-res ERA5 surface winds. V10 intended to be ready before the end of 2023, but the work is unfunded. Note that both JTWC & NHC are now ‘best tracking’ the wind radii at least since 2018. The current version V03 is distinctive because of the pTC (9X ‘invests’) data and rainfall from three satellite-based analyses. For more information, see this presentation, which is the talk Michael Fiorino gave at the Huracán kick-off day in March. It shows some of the features of the pTC data, such as how, in developing pTC, the wind shear drops 48 h before genesis.
