Supplementary Videos — STRATA: Global Km-Scale Autoregressive Atmospheric Emulation

All videos show a 24-hour free rollout at 4.9 km horizontal resolution and 10-minute temporal resolution.

Global overview

Near-surface specific humidity and precipitation, full globe, 24-hour rollout.

Zoom-in: Tropical cyclone (S. Indian Ocean)

Multi-armed spiral structure, eyewall convection, and precipitation banding.

Zoom-in: Shallow clouds (SE Pacific)

Cellular boundary-layer convection preserved rather than smoothed to a mean state.

Zoom-in: Midlatitude cold front (N. Atlantic)

Sharp frontal line in vertical velocity and narrow precipitation band along the cold front.

Zoom-in: Intertropical Convergence Zone (Indo-Pacific)

Organized deep convection along the ITCZ with gravity wave structures.

Zoom-in: Maritime Continent

Land–sea organized convection with diurnal cycle and complex orographic effects.

Zoom-in: Orographic precipitation (Northern Andes)

Topographically forced precipitation along the eastern Andes slopes.
