DESCRIPTION
Slide 3 The value of higher resolution Many features of the real atmosphere are still grossly under-resolved in models (especially for ensemble systems and in severe weather conditions) Errors from under-resolved scales affect the entire spectrum of motions Increases in resolution lead to reduced systematic errors and better kinetic energy spectra More observations can be used at higher resolution, and more information can be extracted from observations Resolution increases have accounted for a significant proportion of past improvements in forecast skill CAS2K7 Lecture
