soil and vegetation conditions in these mountainous regions, affecting ecosystems and phenomena such as wildfire timing, extent, and length of season ( Westerling et al. 2006 ). Because of the complexity of mountainous terrain, snow mass and snow extent exhibit great spatial heterogeneity, with their variability being influenced by a range of factors such as elevation, vegetation cover, slope and aspect, topography, orographic effects, wind redistribution, and atmospheric circulation (e

cover at various scales affects both the local weather status and the Asian summer monsoon ( Blanford 1884 ; Xiao and Duan 2016 ). Snowmelt in spring also serves as an important water supply to some large river systems on the TP ( Han et al. 2019 ). Snow is therefore a key component in the Tibetan climate system. The characteristics of snow on the TP is quite different from that in the circum-Arctic region ( Wang et al. 2018 ). Due to the low latitude of the TP, the solar radiation is strong

satellite- and ground-based observations to confirm a previously inferred inverse relationship between winter snow cover over western Eurasia and subsequent Indian summer monsoon rainfall. Several observation-based studies have shown that Eurasian snow cover influences the state and persistence of the Arctic Oscillation ( Cohen and Entekhabi 1999 , 2001 ; Bojariu and Gimeno 2003 ; Saito and Cohen 2003 ; Saunders et al. 2003 ), which in turn affects the severity of the winter season in the entire

Introduction With its high albedo, low thermal conductivity, and considerable spatial and temporal variability, seasonal snow cover overlying land plays a key role in governing the earth’s global radiation balance; this balance is the primary driver of the earth’s atmospheric circulation system and associated climate. Of the various features that influence the surface radiation balance, the location and duration of snow cover compose two of the most important seasonal variables. In the Northern

1. Introduction Documenting the interannual variability of major components of the cryosphere such as hemispheric sea ice (e.g., Cavalieri et al. 1997 ) and snow cover extent (e.g., Robinson et al. 1993 ) is important for climate change detection, validation of GCM climate simulations, and greater understanding of climate–cryosphere interactions. Snow cover extent (SCE) is an important component of planetary albedo and has been shown to exhibit a close negative relationship with hemispheric

water vapor ( Joshi et al. 2006 ). Our focus is on the possible dynamical relationship between October snow cover extent (SCE) and the boreal winter AO as first demonstrated in Cohen and Entekhabi (1999) . Cohen and Jones (2011a) developed a new index not based on the monthly extent of snow cover but rather on the rate of advance of snow cover south of 60°N that is even more highly correlated with the winter AO ( r ~ 0.8) referred to as the snow advance index (SAI).
