Machine learning augments physics-based weather models by learning from large, heterogeneous datasets. It enhances nowcasting, short- to medium-range forecasts, and uncertainty quantification. Data streams from satellites, radar, in-situ sensors, and reanalyses inform calibrated outputs and transparent evaluation. Constraints grounded in physical laws preserve plausibility, while governance and monitoring ensure reliability and rollback capability. The result is decision-ready forecasts for risk assessment and operational planning, inviting closer scrutiny of where the approach succeeds and where it falters.
