Tropical cyclone tracks<\/h3>\n

Introduction:<\/strong> Below are the tropical cyclone track datasets available for analysis. Tracks are based on the TRACK<\/em><\/a> algorithm (see Hodges et al., 2017<\/a>), with additional tracking using WiTRACK<\/em><\/a> and \u00a0TempestExtremes<\/a><\/em>. Data located on JASMIN are in the Hurac\u00e1n Group Workspace (above), or at the path given (monospace type<\/span>). Additional datasets are available on other platforms (RACC, ECMWF, DKRZ) will be migrated to JASMIN. New datasets will be added as Hurac\u00e1n<\/em> progresses. If you encounter any errors or broken paths, please inform Kevin Hodges<\/a>, Pier Luigi Vidale<\/a> or Alex Baker<\/a>.<\/p>\n

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<\/a>, which is the talk Michael Fiorino gave at the Hurac\u00e1n 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.<\/p>\n

Python2.7 code developed to list (post-)TCs and do analysis is available here<\/a> and documented here<\/a>.<\/p>\n
