Ensemble forecasts generate multiple weather predictions to account for uncertainties. Imagine running a weather model many times, each with slightly different starting conditions. By analyzing the range of these forecasts, we gain a better understanding of the most likely weather scenario and its potential variability.
The charts here use data from the Global Ensemble Forecast System (GEFS), a version of the GFS model run 30 times to provide this range of forecasts. pen_spark
