Global cyclone and anticyclone tracks, 2023-2025 [Update]

Brief description

This record was harvested by RDA at 2026-10-08T11:58:32.650368+11:00 from NCI's Data Catalogue where it was last modified at 2026-06-08.

Full description

This dataset contains global surface anticyclones and both surface and 500 hPa cyclones tracked using the University of Melbourne cyclone tracking scheme over the years 2023 to 2025. It updates an earlier version by extending the data period beyond 2022. The methodology and underpinning datasets are unchanged, but only the ERA5 and NCEP1 datasets have been extended.

Lineage

This dataset is an update of the following dataset: https://dx.doi.org/10.6084/m9.figshare.24086898.v1 Cyclones and anticyclones were identified using the Murray and Simmonds tracking scheme and later refinements. Code and documentation: https://cyclonetracker.earthsci.unimelb.edu.au/ Example processing scripts: https://github.com/apepler/cyclonetracking The included .incycloc and .intrack files record the tracking parameters used.
