What time range does Microsoft’s new AI framework aim to improve in weather forecasting?
✅ Correct Answer: 2–6 weeks (Sub-seasonal Forecasting)
On 14 October 2026, Microsoft Research highlighted its new machine-learning framework, Probabilistic Bias Correction (PBC), designed to improve weather forecasts for the challenging two-to-six-week period.
Rather than replacing existing forecasting models, PBC learns from their historical errors and corrects systematic biases. This approach could improve predictions of temperature, rainfall and atmospheric pressure, helping farmers, water managers and disaster-response teams plan ahead.
