Temporal Context Conditioning for Seasonality-Aware Precipitation Nowcasting of High-Intensity Rainfall
Researchers have developed a new deep learning model called the Time-Aware Small-Attention U-Net (TA-SmaAt-UNet) to improve precipitation nowcasting, particularly for high-intensity rainfall events. This model incorporates lightweight temporal conditioning layers that use cyclical encodings of time-of-day and time-of-year to enhance feature representations. Experiments demonstrated that this temporal context is most beneficial for rare, intense rainfall, while also improving the representation of seasonal variability and rainfall intensity distributions.
