1. Introduction Increasing water demands and climate variability in the face of finite water supply are of particular concern in Nevada and eastern California and across the greater southwestern United States. Drought is a complex phenomenon that can have several different meanings; for example, a simple precipitation P deficit is commonly referred to as meteorological drought, while hydrologic and agricultural drought refers primarily to the availability of surface and groundwater and soil

These interactions include orographic blocking and frontal retardation windward of the Sierra Nevada ( Steenburgh and Blazek 2001 ; Shafer et al. 2006 ), discrete frontal propagation across the Sierra–Cascade ranges and Intermountain West ( Steenburgh et al. 2009 ), and frontal distortions produced by basin-and-range and other topographic geometries ( Steenburgh and Blazek 2001 ; West and Steenburgh 2010 ). In addition, West and Steenburgh (2010) describe how the

1. Introduction There are several mountain ranges worldwide that are well-known for generation of large-amplitude mountain waves. These include the Alps, the Andes, or the New Zealand Alps. In the United States, the most thoroughly documented range is the Colorado Front Range (e.g., Lilly and Zipser 1972 ; Clark et al. 2000 ). Another, the Sierra Nevada in California ( Fig. 1 ) has been until recently less well known among scientists, but it is equally well known among amateur and

; Lundquist et al. 2010 ) that influence both accumulation and melt spatial variability. Yet, most mountain regions remain undersampled with respect to in situ data. For example, the Sierra Nevada range (United States), which is one of the most densely sampled regions in the world, has a snow pillow network that samples less than 1% of the snow-dominated area ( Guan et al. 2013 ), much of which is concentrated at middle elevations, leaving most high-elevation regions completely unsampled. As a result, it

1. Introduction Translated as “snow-covered mountain range” in Spanish, the Sierra Nevada (especially the elevations of the High Sierra around Mount Whitney) can be snow covered for most of the year. The range is known for heavy and even legendary snowfalls including the infamous Donner Pass snowstorm of January 1952 ( Ludlum 1952 ). Since snowfalls in the Sierra Nevada can be extreme, relative to most of North America, they require considerable analyses to understand their trends and unique

accumulates as snow ( Pandey et al. 1999 ). Thus, winter snowpack acts as a natural surface reservoir for water that is then released during dry portions of the year. Snowpack provides approximately three-quarters of the annual freshwater supply in the western United States ( Palmer 1988 ; Cayan 1996 ), and 60% of California’s developed water supply originates from the snowpack-dominated Sierra Nevada ( Bales et al. 2011 ). Along with the Colorado River, this natural store of water contributes to the
