This dataset contains data that can be used to reproduce the figures in Jenney et al., (2021) "Drivers of uncertainty in future projections of MJO teleconnections". Most of the files are Matlab structures as described below I. Output from linear baroclinic model (LBM): Geopotential height at 500 hPa description: LBM output for experiments with control MJO and varied mean states name: "z500_.mat" format: matlab structure "out" with fields: ThVh (historical dry static energy & historical winds) ThVs (historical dry static energy & future winds) TsVh (future dry static energy & historical winds) TsVs (future dry static energy & future winds) dimensions: [30 x 128 x 64 x 59] = [ensemble member x lon x lat x simulation day] II. Output from linear baroclinic model (LBM) for MJO perturbed experiments name: "_z500_.mat" experiments: EAST20: 20-degree eastward shifted thermal forcing MEDIUM: lower bound of increased prop. speed experiment FAST: upper bound of increased prop. speed experiment WAVENO: perturbed wavenumber experiment (decreased wavenumber) format, fields, & dimensions: files with format identical to I III. Linearized Rossby wave source name: "rws.mat" format: matlab structure "rws" fields & dimensions: these are described and listed in the structure IV. Stationary Rossby wave number description: K_s computed for individual CMIP6 model mean states and for the multi-model mean wind name: "Ks.mat" format: matlab structure "Ks_struct" fields & dimensions: described and listed in the structure V. Model global mean surface temperature description: global mean surface temperature for individual CMIP6 models for the historical and future periods name: "mmGlobalSfcTemp.nc" format: netcdf file VI. Tropical mean temperature profile description: Tropical mean temperature profile (20S to 20N) for individual CMIP6 models name: "tropical_mean_temp.mat" format: Matlab structure "trop_mean_temp" fields & dimensions: described and listed in the structure VII. Propagating forcing description: Propagating MJO-like idealized thermal forcing used to force the LBM. name: "movT_weak.grd": control forcing "movT_weak_.grd": perturbed MJO cases, naming convention described in II format: binary (.grd file) notes: Use Matlab script "read_forcing.m", also included, to read and plot the files.
