A32F:
Weather and Climate Modeling Across Scales: From Global to Convection-Permitting II


Submit an Abstract to this Session


Session ID#: 58674

Session Description:
The earth system operates across a wide spectrum of scales, ranging from thousands of kilometers to a handful of meters. In recent years, increasing computer power and convection-permitting models (< 4 km horizontal grid spacing) as well as novel techniques such as variable-resolution and multiscale modeling framework are helping to enable high-resolution simulations over large regional, even global, domains at climate time scales. The ability to model smaller scales appropriately has been shown to improve simulations of convection, severe storms, orographic forcing, and their upscale effects to the large-scale circulation.

This session seeks contributions regarding the development or application of high-resolution simulations and multi-scale techniques for investigating weather and climate, such as the impact of climate change on processes at local scales (e.g., precipitation, hydrology and ecosystems) and teleconnections across scales. We also invite papers addressing sensitivities arising from the response of model physics and dynamics to multiple resolutions.
