Title: Identifying Trends in the Spatial Errors of a Regional Climate Model via Clustering

Abstract: In this talk, we propose a statistical modeling approach to determine whether different spatial fields display a similar spatial gradient. The application we consider is rooted in atmospheric sciences: more specifically, our scientific interest is in determining whether there exist time periods during which a particular regional climate model – the RCA model run by the Swedish Meteorological and Hydrological Institute – displays the same type of spatial discrepancies from the observations. The proposed model can be seen as an exploratory tool for atmospheric modelers to identify time periods that require a further in-depth examination. Focusing on seasonal average temperature and seasonal maximum temperature for Southern Sweden during the period December 1, 1962 to November 30, 2007, our analysis reveals intriguing tendencies with respect to the RCM spatial errors relative to seasonal average temperature; on the other hand, no systematic spatial error is detected for seasonal maximum temperature during the period 1963-2007
