Comparison of Analysis and Spectral Nudging Techniques for Dynamical Downscaling with the WRF Model over China

Figure 4

Time series plots of related statistical verification techniques for the daily accumulated precipitation in May and June 2011. (a) The ME between the observations and downscaling results by WRF by NN, AN and SN; (b) the same as (a), but is the RMSE; (c) the same as (a), but is the cc; (d) BS at the threshold of 10 mm (if the BS value is greater than 3, we set it as a missing value because it indicates much overprediction of precipitation and makes it difficult to understand the plot); (e) TS at the of 10-threshold mm.
