Warming and Earlier Spring Increase Western U.S. Forest Wildfire Activity
It is shown that large wildfire activity increased suddenly and markedly in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons.
Changes toward Earlier Streamflow Timing across Western North America
Abstract The highly variable timing of streamflow in snowmelt-dominated basins across western North America is an important consequence, and indicator, of climate fluctuations. Changes in the timing
Changes in the Onset of Spring in the Western United States
Abstract Fluctuations in spring climate in the western United States over the last 4–5 decades are described by examining changes in the blooming of plants and the timing of snowmelt–runoff pulses.
Latent and sensible heat flux anomalies over the northern oceans : driving the sea surface temperature

Abstract A part of the large-scale thermodynamic forcing of the upper ocean is examined by relating monthly anomalous latent and sensible heat flux to changes in sea surface temperature (SST)
Trends in Snowfall versus Rainfall in the Western United States
Abstract The water resources of the western United States depend heavily on snowpack to store part of the wintertime precipitation into the drier summer months. A well-documented shift toward earlier
Climate change scenarios for the California region
To investigate possible future climate changes in California, a set of climate change model simulations was selected and evaluated. From the IPCC Fourth Assessment, simulations of twenty-first
Atmospheric Rivers, Floods and the Water Resources of California
California's highly variable climate and growing water demands combine to pose both water-supply and flood-hazard challenges to resource managers. Recently important efforts to more fully integrate
North Pacific Decadal Climate Variability since 1661
Abstract Climate in the North Pacific and North American sectors has experienced interdecadal shifts during the twentieth century. A network of recently developed tree-ring chronologies for Southern
ENSO and Hydrologic Extremes in the Western United States
Frequency distributions of daily precipitation in winter and daily stream flow from late winter to early summer, at several hundred sites in the western United States, exhibit strong and systematic
Emissions pathways, climate change, and impacts on California.
It is found that annual temperature increases nearly double from the lower B1 to the higher A1fi emissions scenario before 2100, and three of four simulations also show greater increases in summer temperatures as compared with winter.
