A new deep learning model by University of Washington enhances weather and climate forecasting accuracy by integrating atmospheric and oceanic data.
In an innovative stride for meteorological science, a new deep learning model developed by Dale Durran, a professor in the Atmospheric Sciences Department at the University of Washington, is setting new standards in weather and climate prediction accuracy. According to the NVIDIA Technical Blog, this breakthrough model effectively combines atmospheric and oceanic data to enhance forecasting precision.
Presented during an NVIDIA GTC 2024 session, the model leverages advanced techniques that minimize dependency on traditional parameterizations, thereby bypassing many approximations typically used in weather prediction. A notable feature is the employment of a HEALPix grid, a mesh originally from astronomy, which enhances spatial precision by accurately representing Earth’s spherical form, thus eliminating distortions in global forecasts.
Utilizing NVIDIA A100 Tensor Core GPUs, the model is capable of generating reliable, long-term forecasts with minimal drift. It integrates machine learning simulations using NVIDIA Modulus and high-fidelity visualizations through NVIDIA Omniverse, significantly boosting the accuracy and interpretability of climate forecasting.
The deep learning model incorporates several advanced methods for building accurate, long-term Earth system models:
The introduction of this deep learning model marks a significant advancement in the field of meteorology, promising to improve the accuracy of long-range weather and climate forecasts. As climate change continues to pose challenges globally, such advancements are crucial in aiding preparation and response strategies.
For those interested in exploring more about the model and its applications, the session “Sub-Seasonal and Seasonal Forecasting with a Deep Learning Earth-System Model” is available on NVIDIA On-Demand. This session, along with other resources, provides valuable insights and skills from industry experts. Participants can further enhance their knowledge by joining the NVIDIA Developer Program.
