Use of Deep Learning for Weather Radar Nowcasting
Problem
Operationally deployed weather radar nowcasting systems did not use deep learning; the study explored deep learning alternatives for predicting future radar echoes.
Why it matters
Nowcasting of radar echoes supports short-term severe weather warnings and public safety.
What the AI did
Deep learning models using residual convolutional encoder-decoder architectures estimated future radar echoes from current and past observations and were compared against operational nowcasting systems.
Results
Reached performance expected of current operational systems and outperformed them in certain scenarios; no performance decay on a different geographical area; no edge or checkerboard artifacts affecting metrics.
Impact
Deep learning matched and sometimes exceeded operational nowcasting systems, though no numeric benchmarks are given in the abstract.
