As for how this could be — and in light of the findings of the references listed above — Rankl et al. reasoned that «considering increasing precipitation in winter and decreasing summer mean and minimum temperatures across the upper Indus Basin since the 1960s,» plus the «short response times of small glaciers,» it is only logical to conclude that these facts «suggest a shift from negative to balanced or positive mass budgets in the 1980s or 1990s or even earlier, induced by changing climatic conditions since the 1960s.»

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

2: Our Changing Climate, Key Message 5).2 Regional climate models (RCMs) using the same emissions scenario also project increased spring precipitation (9 % in 2041 - 2062 relative to 1979 - 2000) and decreased summer precipitation (by an average of about 8 % in 2041 - 2062 relative to 1979 - 2000) particularly in the southern portions of the Midwest.12 Increases in the frequency and intensity of extreme precipitation are projected across the entire region in both GCM and RCM simulations (Figure 18.6), and these increases are generally larger than the projected changes in average precipitatIncreases in the frequency and intensity of extreme precipitation are projected across the entire region in both GCM and RCM simulations (Figure 18.6), and these increases are generally larger than the projected changes in average precipitatincreases are generally larger than the projected changes in average precipitation.12, 2

One sentence summary: A strengthened subtropical jet stream — which is the primary means by which El Niño brings increased precipitation to California — is unlikely to occur prior to winter due to the intrinsic seasonal cycle of temperature variations across the Pacific Basin.

A warmer atmosphere drives more extreme precipitation across all storm types, which in turn increases the the risk of flooding.
