Abstract

These data are the tropical storm tracks calculated using the "TRACK" storm tracking algorithm. The storm tracks are from experiments run as part of HighResMIP (High Resolution Model Intercomparison Project; Haarsma, R. J. and co-authors) a component of the Coupled Model Intercomparison Project Phase 6 (CMIP6). The raw HighResMIP data are available from the Earth System Grid Federation (ESGF), here the calculated storm tracks are available.

The storm tracks are provided as Climate Model Output Rewriter (CMOR)-like NetCDF files with one file per hemisphere for all years in the simulated period of HighResMIP experiments:
1950-2014 - highresSST-present, atmosphere-only;
2015-2050 - highresSST-future experiment, atmosphere-only;
1950-2050 – control-1950, coupled atmosphere-ocean;
1950-2014 – hist-1950, coupled atmosphere-ocean;
2015-2050 – highres-future, coupled atmosphere-ocean using SSP585 scenario.
There is one tracked variable in each file with time, latitude and longitude coordinates associated at each six-hour interval.

Other variables associated with each track are also provided, e.g. the minimum or maximum value adjacent to the track of the variable of interest and these variables have their own latitude and longitude coordinate variables. If a maximum/minimum value is not found, then a missing data value is used for the respective latitude-longitude values.

Title TRACK computation for CMIP6 HighResMIP storm tracks
Abstract The storm tracking algorithm TRACK (Hodges, et. al., 2017) uses 850 hPa vorticity, averaged over 850, 700, 600 hPa, and filtered to T63 spectral grid, to find storm candidates. It then uses the vertical gradient of vorticity to determine if there is a warm core this with other conditions determine whether a tropical storm is identified. The algorithm used for the storm-tracking is also described in the metadata of the track files and full details can be found in the linked documentation. The storm tracks were calculated using the Lotus cluster at on the JASMIN compute facility at the Centre for Environmental Data Analysis (CEDA).
