For weather, 6-10 day, and 8-14 days it means getting the current conditions (or initial conditions) of the atmosphere, ocean, land as close to reality as possible.

How accurate are seasonal forecasts?

Extensive seasonal hindcasting, leveraging more than three decades of weather data, has validated that the AER suite of seasonal weather forecasts accurately predicts the temperature direction (higher or lower) 80% of the time, and the magnitude of the predicted temperature anomaly is a 30-50% improvement over using …
