The Global Environmental Multiscale Model (GEM) runs at a horizontal resolution of 0.24° x 0.24°. This is widely considered the best global NWP model currently available. It is updated twice each day and provides forecast data for up to 240 hours ahead. View GEFS charts ECM (European Centre for Medium Range Weather Forecasts)Ī global model run at a horizontal resolution of 0.1° x 0.1°. A bigger spread means more uncertainty and lower forecast confidence. They are an attempt to account for uncertainty with the aim being for the outcome to fall within the predicted ensemble spread. The runs use slightly different initial atmospheric conditions that are all plausible given the past and current set of observations or measurements.
