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. Contents: Equatorial zonal‑mean zonal wind (averaged over 5°S–5°N) as a function of time and pressure (March 2020 – February 2021) from: CAS‑ESM2 10‑km explicit‑convection experiment CAS‑ESM2 10‑km parameterized‑convection experiment CAS‑ESM2 25‑km parameterized‑convection experiment ERA5 reanalysis (reference) Monthly equatorial zonal wind at 30 hPa and 50 hPa (5°S–5°N) for the same four datasets. TEM (Transformed Eulerian‑Mean) zonal‑momentum budget terms (total tendency, meridional and vertical EP flux divergence, meridional and vertical advection by residual circulation) averaged over 5°S–5°N, for all experiments and ERA5. Precipitation rate (3‑hourly) and vertical pressure velocity at 500 hPa over tropical oceans (5°S–5°N) used for convective intensity and wave‑activity analyses.
