Testing the downscaling ability of a one-way nested regional climate model in regions of complex topography

Abstract: The downscaling ability of a one-way nested regional climate model (RCM) is evaluated over a region subjected to strong surface forcing: the west of North America. The sensitivity of the results to the horizontal resolution jump and updating frequency of the lateral boundary conditions are also evaluated. In order to accomplish this, a perfect-model approach nicknamed the Big-Brother Experiment (BBE) was followed. The experimental protocol consists of first establishing a virtual-reality reference climate over… Show more

“…The sensitivity of regional climate modeling to the size of the chosen domain is an issue of both interest and some controversy. A notable line of study has been the ‘Big Brother/Little Brother’ experimentation 19–22. Its basic setting is to first run an RCM at high resolution over a large domain (Big Brother).…”

“…Due to the limitation of RCMs' downscaling ability, some studies have applied multiple initializations but still examined the climate statistics, such as monthly and seasonal means. Studies indicate that when the LBC data have good quality, more frequent reinitialization and/or frequent coupling with LBCs should help the RCM dynamic downscaling ability (e.g., Lucas-Picher et al, 2013;Antic et al, 2006;Gao et al, 2007;Di Luca et al, 2012).
