Highly accurate advection solver CIP is firstly applied to meteorological model MM5. Improvement of model accuracy and computational performance are observed. In addition to three ideal advective experiments, a case simulations of mesoscale weather system is presented. In comparison with the original Leap-frog scheme in MM5,CIP produced better rainfall position and amount. Realistic spatial distribution of mesoscale systems in successfully described with the CIP scheme.
