Methods
Data collection and processing 

Results of the extended Plateau simulations ("Plateau_control", "Plateau_3deg", "Plateau_6deg", "Plateau_10deg")

We used the Community Earth System Model (CESM) 1.2.2 and chose the component set "F_1850_CAM5", which includes the coupler, active atmosphere, land, and ice components, and a data ocean. The atmospheric component is the Community Atmosphere Model version 5 (CAM5) at 0.9x1.25 horizontal resolution and 30 layers of vertical resolution. The sea surface temperature is prescribed using observed monthly climatology. Each simulation was integrated for 25 years; outputs archived here are pentad climatologies derived from the last 20 model years. Please refer to Kong and Chiang (2019) for more details. 

Archived variables: U, V, PRECT, PRECC, PRECL, and Theta_e

Results of the idealized dry dynamical core simulations

We used the finite-volume dynamical core of CAM5, e.g. the component set "F_IDEAL_PHYS". Each simulation was integrated for 5 years; outputs archived here are climatologies derived from the last 3 model years. Please refer to Kong and Chiang (2019) for more details.

Archived variables: U, V, eddy height at 500mb, QG stream function, three-dimensional EP flux
