The DYMECS Project: A Statistical Approach for the Evaluation of Convective Storms in High-Resolution NWP Models

“…Subkilometer-scale models are emerging from being run experimentally to actually aiding forecasts: for instance, the London and Weymouth 333-m models (Golding et al 2013;Wang et al 2013), model development for the High Definition Clouds and Precipitation for Climate Prediction project, and Environment Canada's highresolution model development for outdoor venues at the 2015 Toronto Pan-Am Games. We therefore require novel observational strategies and diagnostic tools for model evaluation.…”

Comparison between high-resolution climate simulations using single- and double-nesting approaches within the Big-Brother experimental protocol

“…Cholette et al (2015) have shown that with grid meshes of 1-3 km, the fifth-generation Canadian Regional Climate Model (CRCM5) showed a clear improvement in the simulation of wind channelling effect in the St. Lawrence River Valley located in Québec, Canada. The study of Wang et al (2013) revealed that high resolution improves local features such as sea breezes and funnelling winds in the Met Office United Model (MetUM) RCM. In the case of simulations over complex topography with the Weather Research and Forecasting (WRF) RCM version 3.0, Rasmussen et al (2011) have shown that spatial snowfall distribution is much more representative of observations with 2 km than 36 km grid-mesh simulations; they attributed this result to a more realistic vertical motion at higher resolution.…”

Superensemble Regional Climate Modeling for the Western United States

“…Regional climate models (RCMs; e.g., Giorgi 1990) have been implemented over specific areas of interest with resolutions as high as 500 m (Wang et al 2013) compared to 50-300 km for a GCM. Typically, such studies run the RCM one or at most a handful of times.…”
