This dataset contains data that can be used to reproduce the figures in Jenney et al., (2021) " Mechanisms driving MJO teleconnection changes with warming in CMIP6". Most of the files are Matlab structures as described below I. Output from linear baroclinic model (LBM): meridional wind at 850 hPa description: LBM output for experiments with control MJO and varied mean states name: "v850_.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: "_v850_.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 STRONG: 20% stronger thermal forcing 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.
