Global High-Resolution Model Analysis

With advances in high-performance computing, many climate modeling centers have begun developing global climate model simulations with kilometer-scale horizontal resolution, allowing them to resolve finer-scale physical processes that were previously parameterized. These models, often termed global storm-resolving models, are useful for addressing a wide range of research problems, such as air–sea interactions over boundary currents, the life cycle of mesoscale extratropical cyclones, eddy–eddy interactions, the properties of extreme precipitation, extratropical transition, and localized extreme weather events.

Although storm-resolving model outputs are often not yet publicly available due to their enormous size, researchers can access these data through archives at major modeling centers, supported by international model intercomparison initiatives such as the DYAMOND project or kilometer-scale hackathon. Our group is interested in using storm resolving model simulations to explore the effects of kilometer-scale resolution on midlatitude atmospheric circulation and surface climate.
