Probability calibration for precipitation nowcasting
CoRRReliable precipitation nowcasting is critical for weather-sensitive decision-making, yet neural weather models (NWMs) can produce poorly calibrated probabilistic forecasts. Standard calibration metrics such as the expected calibration error (ECE) fail to capture miscalibration across precipitation thresholds.

Application of PFI-4DVar Data Assimilation Technique to Nowcasting of Numerical Model
应用气象学报, 2020 Nowcasting is mainly based on radar echo or satellite image extrapolation method. However, the prediction ability of extrapolation method decreases with time, because this method cannot describe the physical mechanism during the occurrence, development ...

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part II: Verification
Quarterly Journal of the Royal Meteorological Society, EarlyView.In this work we present the verification of the NowPrecip precipitation nowcasting systems (version 1 and version 2). Using 3.5 years of data over the period 2020–2023, their performance is compared with PySTEPS and the ICON numerical weather prediction ensemble by computing deterministic and probabilistic metrics.
