I would like to know how the resolution of a Numerical Weather Prediction model conceptually works.
"Global Forecast System's forecasts with 0.5° horizontal spatial resolution"
"NCEP’s reforecast is based on the Global Ensemble Forecast System (GEFS), which has horizontal grid increments of approximately 1°."
Are these two sentences talking about the same thing? In this case, GFS has more resolution, doesn't it?
