Data for "Improved Simulation of the Quasi‑Biennial Oscillation in CAS‑ESM2 Enabled by Explicit Deep Convection"

This dataset contains the primary model output and reanalysis data used in the above study, which evaluates the simulation of the quasi‑biennial oscillation (QBO) in CAS‑ESM2 at kilometer‑scale resolutions. Four experimental groups are included: CAS‑ESM2 10‑km explicit‑convection experiment (10km_nocumulus) CAS‑ESM2 10‑km parameterized‑convection experiment (10km_cumulus) CAS‑ESM2 25‑km parameterized‑convection experiment (25km_cumulus) ERA5 reanalysis (reference) The dataset contains the following variables: Equatorial zonal‑mean zonal wind (averaged over 5°S–5°N) as a function of time and pressure, for all four groups. Monthly equatorial zonal wind at 30 hPa and 50 hPa (5°S–5°N) for the same four groups. TEM (Transformed Eulerian‑Mean) zonal‑momentum budget terms (total tendency, meridional and vertical EP flux divergence, meridional and vertical advction by residual circulation) averaged over 5°S–5°N, for all experiments and ERA5. Precipitation rate over 5°S–5°N. Upward pressure velocity at 500 hPa over 5°S–5°N. Data format: NetCDF files (see the accompanying README for details).
