Recently, the International Laboratory for High-Resolution Earth System Prediction(iHESP) jointly established by Qingdao National Laboratory for Marine Science and Technology, Texas A&M University and National Center for Atmospheric Research has seen its paper entitled “An Unprecedented Set of High‐resolution Earth System Simulations for Understanding Multiscale Interactions in Climate Variability and Change” published in the section of “Editors’ Highlights” on AGU Eos.
AGU Eos is an authoritative platform for releasing news on the world’s cutting-edge development of earth and space sciences. Its section of “Editors’ Highlights” is specially dedicated to briefing the most influential research progress in a specific area, that less than 2% papers can be featured by this section.
Eos points out that iHESP is the first to simulate the coupled Earth system at fine enough resolution to explicitly resolve ocean mesoscale eddies and permit tropical cyclones while at the same time running long enough to convincingly capture equilibrated pre-industrial conditions, historical evolution of anthropogenic climate change, and near-term future predictions. This is a big deal because recent studies and process-level understanding suggest that coarser resolution is a major source of model deficiencies, yet previous high-resolution studies have been too short to provide an adequately equilibrated pre-industrial state or to capture the full history of anthropogenic climate change.
With 750 simulated years of data, this study is also able to explore for the first time decadal-scale variability in a model which captures more scales of motion. This novel research identifies a connection between openings in Antarctic sea ice (called polynyas) and the Interdecadal Pacific Oscillation, which affects weather throughout the Pacific Basin. Because the model output presented in this study will be publicly available, this study is sure to form the foundation for a lot of great research.
