What does the acronym StormSPEED stand for?
What does the acronym StormSPEED stand for?
StormSPEED stands for 'Storm-resolving SPEctral Element Dycore'. The acronym points to the nonhydrostatic Spectral Element dynamical core from the Department of Energy (DoE) that StormSPEED integrates into the CESM3 framework to enable storm-resolving Earth system simulations.
When did StormSPEED start?
When did StormSPEED start?
The StormSPEED project started in February 2024. Its initial phase will run until 2027.
Why does StormSPEED pursue storm-resolving Earth system modeling efforts?
Why does StormSPEED pursue storm-resolving Earth system modeling efforts?
As the ever-increasing impacts of weather and longer-term changes are being felt by ordinary people as heat waves, droughts, hurricanes, or sea level rise, just to list a few, decision makers and stakeholders need weather and Earth system information at the spatial and temporal scales that matter for these events. Such emerging and societally-relevant demands represent a Grand Challenge for the Earth system community, including CESM, requiring both much finer spatial resolution (order 3-10 km) than typically used and a step change in our scientific understanding of processes occurring at these scales.
Are there related storm-resolving modeling efforts in the science community?
Are there related storm-resolving modeling efforts in the science community?
There are about 10 efforts under way by the international weather and Earth system modeling community to build storm-resolving general circulation models (GCMs). Most models are uncoupled and utilize prescribed ocean and sea-ice conditions for past time periods. The most comprehensive assessment of storm-resolving GCMs so far has been driven by the DYAMOND Initiative: https://www.esiwace.eu/the-project/past-phases/dyamond-initiative
What are StormSPEED's scientific drivers?
What are StormSPEED's scientific drivers?
Two exemplars serve as the StormSPEED science drivers. They focus on (i) the interactions of extreme, convectively-driven precipitation (in particular Mesoscale Convective Storm Systems) over the Continental United States with the large-scale flow and (ii) the impact of multi-scale ocean-atmosphere interactions on tropical precipitation and cyclones. StormSPEED thereby builds bridges between the mesoscale and large-scale scientific communities and provides scientific insights into the impacts of mesoscale motions on the Earth system.
What is the CESM model?
What is the CESM model?
The Community Earth System Model (CESM) is a collaborative, community modeling effort between researchers at the NSF NCAR NCAR, universities, and other national and international research institutions. In addition, several CESM components, such as the ocean and sea-ice components, are developed by partners like the NOAA Geophysical Fluid Dynamics Laboratory (GFDL) and the CICE consortium for sea ice. The release of version 3 (CESM3) is planned for 2025. Learn more about CESM here: https://www.cesm.ucar.edu/
