Emerging DYAMOND-class Global storm-resolving models (GSRMs) are a powerful tool to better understand kilometer-scale phenomena and their interactions with synoptic and planetary scale motions. I present results from multi-year runs of the GFDL eXperimental System for High-resolution Prediction on Earth-to-Local Domains (X-SHiELD) in both present-day and warmed climates. I focus on the properties of intense and rotating convection, and on kilometer-scale orographic precipitation. The simulations show that rotating convection is common worldwide and that usually, but not always, favors cyclonic rotation. In a warmed climate, intense deep convection broadly increases with some regional shifts explicable by changes to the larger-scale circulations.
