This session invites contributions on all aspects of atmospheric dynamics and predictability ranging across spatial and temporal scales (meso-, synoptic-, planetary scale motions) and from daily (nowcasting) to seasonal time scales and beyond (multidecadal variability).

Particularly welcome are contributions, which focus on scale interactions, connect across latitudes or are particularly relevant for operational forecasting systems. This includes, but is not limited to, contributions such as:
The interaction between diabatic processes and the large-scale circulation (observations, reanalysis, LES, cloud-resolving).
The influence of remote factors, e.g., stratospheric, artic or tropical variability, on midlatitude weather and climate patterns and seasonal predictability (ENSO, sudden stratospheric warming).
The orographic influence on cyclones, fronts and high-impact precipitation / hail.
Weather regimes and dynamics of extreme events (cyclone clustering, sting jets, blocking periods).
