Do you trust that new machine learning models will make local weather forecasts more accurate?
Scientists have introduced a hybrid machine learning model called FuXi-RTM designed to improve the accuracy of global weather forecasting. By integrating a radiative transfer model surrogate, the system provides better predictions for complex atmospheric variables.
Why it matters
Clouds, radiation, and surface albedo have historically been difficult to represent accurately in global systems. This model addresses those challenges to provide more reliable atmospheric data.
The FuXi-RTM model utilizes radiative transfer gradients to constrain forecast states. It is specifically designed to improve shortwave radiation and cloud-related variable forecasts globally.
