Projections of Potential Flood Regime Changes in California
(2009-03)
Floods have been a recurring theme in California’s climatology, hydrology, and politics
throughout its history. Today, California's aging water supply and flood protection
infrastructures are challenged by major floods ...
Downscaling With Constructed Analogues: Daily Precipitation and Temperature Fields Over The United States
(2008-01)
Daily precipitation and average temperature patterns for the contiguous United States were
downscaled from a 2.5 x 2.5 degree (coarse) resolution grid to a 1/8 x 1/8 degree (fine) resolution
grid using a constructed‐analogues ...
Detection and Attribution of Streamflow Timing Changes to Climate Change in the Western United States
(2009-07)
This article applies formal detection and attribution techniques to investigate the nature of observed shifts in the timing of streamflow in the western United States. Previous studies have shown that the snow hydrology ...
California Climate Change Center Report Series Number 2008-0XX
(2008-06)
Four dynamic regional climate models (RCMs) and one statistical downscaling
approach were used to downscale 10 years of historical climate in California. To isolate
possible limitations of the downscaling methods, we ...
Sources of Variability of Evapotranspiration in California
(2005-02)
The variability (1990–2002) of potential evapotranspiration estimates (ETo) and related meteorological variables from a set of stations from the California Irrigation Management System (CIMIS) is studied. Data from the ...
A method for prediction of California summer air surface temperature
(2004-12-21)
While significant progress has been made in seasonal climate prediction in recent years, summertime mid-latitude climate prediction remains problematic [e.g., Gershunov and Cayan, 2003]. Several previous studies have ...
Detection and Attribution of Temperature Changes in the Mountainous Western United States
(2008-04-22)
Large changes in the hydrology of the western United States have been observed since the mid-twentieth century. These include a reduction in the amount of precipitation arriving as snow, a decline in snowpack at low and ...
Changes in Aridity in the Western United States
(2008-08)
It is often remarked that most of the western US (Figure
1) is “always in drought,” especially by visitors from wetter
climates. The plants and landforms of the West, however, are more or less adapted to the region’s ...
Structure and Detectability of Trends in Hydrological Measures over the Western United States
(2009-08)
This study examines the geographic structure of observed trends in key hydrologically relevant variables across the western United States at ⅛° spatial resolution during the period 1950–99. Geographical regions, latitude ...
Human-Induced Changes in the Hydrology of the Western United States
(2008-02-22)
Observations have shown that the hydrological cycle of the western United States changed significantly over the last half of the 20th century. We present a regional, multivariable climate change detection and attribution ...
