Drivers of TCs in the SWIO based on 5 CMIP6 Models

This dataset provides monthly mean air temperature (ta) at multiple atmospheric levels from CMIP6 global climate models, covering both the historical period (1959–2000) and future high-emission SSP585 scenario (2060–2100). The variable is extracted on standard pressure levels, allowing investigation of large-scale thermodynamic conditions and vertical temperature gradients relevant to tropical cyclone (TC) genesis and intensification over the Southwest Indian Ocean (SWIO). The included models are: ACCESS-CM2 CIESM CMCC-ESM2 INM-CM5-0 MPI-ESM1-2-LR Files are distributed in NetCDF format and follow the CMIP6 “Amon” frequency (Atmosphere, monthly). Each file corresponds to one model experiment on its native grid (gn, gr, or gr1). This dataset enables analysis of historical climate variability and projected changes in atmospheric thermal structure under a warming climate, providing critical input for studies of tropical cyclone dynamics and drivers in the SWIO.
