in realistically simulating or producing surface fluxes and skin temperature (e.g., Jiménez et al. 2011 ; Decker et al. 2012 ). Skin temperature ( T s ) plays a significant role in the land surface energy balance and is also widely available from remote sensing for model evaluation and data assimilation (e.g., Jin et al. 1997 ; Reichle et al. 2010 ). Over arid and semiarid regions that represent one-third of the global land, the vegetation evapotranspiration and the closely coupled water

hydrologic and atmospheric model performance ( Betts 2004 , 2009 ). By linking the surface, PBL, and cloud processes, coupling encompasses complex cross-scale interactions that determine the climate state. Coupling strength varies on local (5–10 km) to regional scales (400 km) and temporally on daily to weekly time scales ( Betts 2004 ; Koster et al. 2003 ; Taylor and Ellis 2006 ), modulated by background synoptic weather (i.e., convergence/divergence, monsoons, and cloud fields) and larger scale (i

observations, and it is particularly well suited to isolate the impacts of land surface perturbations on the PBL (and vice versa) that are crucial for sustaining flood and drought conditions. With these issues in mind, this paper presents results from case studies of dry/wet extremes in the U.S. southern Great Plains (SGP) to evaluate the performance of and coupling between a range of land surface models (LSMs) and PBL schemes (PBLs) by employing recently developed diagnostics of LoCo. Specifically, the

; Gutiérrez and Hernandez 1996 ; Mora and Iverson 1998 ; Descroix et al. 2002a , b ). Descroix et al. (2007) evaluated the role of soil and vegetation characteristics on infiltration- and saturation-excess runoff mechanisms at four sites in Mexico through a modeling approach and comparisons with field data. The authors found that both runoff mechanisms were scale dependent and decreased with larger catchment areas, which is consistent with work by Goodrich et al. (1997) in Arizona. More importantly
