A Coherent Approach to Evaluating Precipitation Forecasts over Complex Terrain

Precipitation forecasts provided by high-resolution NWP models have a degree of realism that is very appealing to most users meteorological data. However, it challenge demonstrate whether or not such contain more skillful information than their lower resolution counterparts. A verification procedure must be based on equally detailed observations are also realistic in areas where ground available and remote sensing data can only increase the accuracy location rain events at cost decreased estimating amount has actually reached ground. Traditional methods station grid point comparison yield poor results for fields due double penalty error attributed finite space time displacement do account for. complete approach evaluating precipitation over complex terrain suggested. The method gridded generated an interpolation uses long climate series determine geographical characteristics this parameter best correlated with as well estimates background cover insufficient. Spatial methodologies subsequently applied convective event accentuate relative skill COSMOGR revealing patterns structure intensity.
