Temperature and precipitation vary greatly with elevation, but in the central basin January average daily temperatures are between about 25 and 30 F (4 and 1 C), and July averages are mostly between 70 and 75 F (21 and 24 C). Small black dots indicate streamflow sites where naturalized flows were not available.
UW Hydro | Columbia River Climate Change - Home Ingalls Weather - Weather reports on whatever I decide to report on. For climate change studies in the western United States where snow is an important element of the hydrologic cycle, the model's use of a sophisticated energy-balance snow model, which incorporates important effects on snow accumulation and melt associated with vegetation canopy (Andreadis, Storck, & Lettenmaier, Citation2009) has been a notable advantage. The Columbia Basin Climate Change Scenarios Project (CBCCSP) was conceived as a comprehensive hydrologic database to support climate change planning, impacts assessment, and adaptation in the Pacific Northwest (PNW) by a diverse user community with varying technical capacity over a wide range of spatial scales. Lows in the upper 30s to lower 40s. In the remainder of this paper, we present an overview of the development of the CBCCSP, a description of the primary methods used to produce the study databases, an overview of the products and information the study databases provide, and some high-visibility examples of the use of these products and services in regional planning. Thanks to Shrad Shukla, at the UW for 1/16 degree VIC model calibration over the Yakima basin. Inset numbers at the upper left in the future projections are the percentage changes in 1 April SWE averaged over each grid cell in the entire domain. 0
To explore how much the model simulations might be improved by additional fine-scale calibration, we also recalibrated three additional smaller sites within the Pend Oreille River basin. In particular, it is clear that Canada will have not only about 50% of the reservoir storage in the CRB (Hamlet, Citation2003) but also an increasingly dominant portion of the natural water storage as snowpack in the future. Bias-correction procedures provide an alternative statistical approach that effectively avoids these difficulties (Shi, Wood, & Lettenmaier, Citation2008; Snover et al., Citation2003). Special thanks to Kurt Unger and Ken Slattery, who were the primary architects of the CBCCSP at WDOE.

All of the meteorological forcing data, except wind speed, are reproduced in the output files produced by the hydrologic model. A key design element of the CBCCSP from the outset of the project was to produce a well-organized and well-documented end-to-end (i.e., GCM to hydrologic products) data processing sequence and a web-accessible data archive that would greatly reduce the cost of producing updates in response to each subsequent CMIP/IPCC cycle. About 15 sites in western Washington, outside the CRB, were also included in support of the 2009 WACCIA. Figure 1 shows a map of the approximately 300 streamflow locations that were ultimately compiled from these lists for inclusion in the study (a spreadsheet listing these sites is available on the CBCCSP website (CIG, Citation2013a)). Has spring snowpack declined in the Washington Cascades? The study has constructed a state-of-the-art, end-to-end data processing sequence from raw climate model output to a suite of hydrologic modelling products that are served to the user community from a web-accessible database. A family of greenhouse gas emissions scenarios used in the IPCC effort (Nakienovi et al. 6 Example of a summary plot for extreme high flows (Q20, Q50, Q100, left panels) and extreme low flows (7Q10, right panels) for the Skagit River at Mount Vernon for two emissions scenarios (A1B, B1) and three future time periods (2020s, 2040s, 2080s). Changes in the 1 April snowpack have been shown to depend strongly on winter temperature regimes (Hamlet, Mote, Clark, & Lettenmaier, Citation2005; Mote, Citation2006; Mote et al., Citation2005). The CBCCSP was founded on the basis of regional partnerships to support a shared need for climate change scenarios and directly encompassed the transboundary nature of the CRB's management framework by including both US and Canadian interests in an integrated and comprehensive data resource. USFWS (US Fish & Wildlife Service). These extensive and ongoing research activities have also been materially supported by the long-term outreach and education programs of CIG, which have, from the outset, fully recognized the transboundary nature of the CRB (Hamlet, Citation2003; Miles et al., Citation2000) and responded by promoting sustained, long-term interaction with CRB researchers and stakeholders in the United States and Canada (Hamlet, Citation2011). This approach was partly based on practical limitations on time and computational resources but was also informed by previous experience using the VIC model at finer spatial scales. The six panels display results from the combination of three time periods (rows) and two emissions scenarios (columns) used in the HD downscaling process. A detailed climate change assessment report was prepared by the CIG for Seattle City Light (Snover et al., Citation2010) based primarily on the CBCCSP database. Note that unlike the raw VIC flux files discussed above (Table 2), imperial units are used for these products on the study website (cubic feet per second, inches, degrees Fahrenheit).
Climate Resilience - Columbia Basin Trust This was coordinated through the River Management Joint Operating Committee (RMJOC), a sub-committee of the Joint Operating Committee which was established through direct funding Memorandum of Agreements between BPA, Reclamation, and the USACE. Confirming the sensitivity to warming demonstrated in earlier studies, the CBCCSP results show widespread reductions in the 1 April snowpack, and systematic reductions in the long-term average SWE2PR, a measure of the importance of snow in the hydrologic cycle (Fig. Many locations could see increases of 100% or more in the 50-year and 100-year flood magnitude, with some smaller tributaries potentially seeing increases of as much as 175%. (Citation2010) also updated the soil depth map using a more sophisticated approach developed for the DHSVM (Wigmosta, Nijssen, Storck, & Lettenmaier, Citation2002; Wigmosta, Vail, & Lettenmaier, Citation1994) that varies soil depth with elevation. In 2008, many of the financial and institutional barriers to climate change assessment and adaptation that had been erected over the preceding eight years by the Bush Administration were substantially reduced by the incoming Obama Administration. The macroscale hydrologic model used in the CBCCSP is the VIC model (Cherkauer & Lettenmaier, Citation2003; Liang, Lettenmaier, Wood, & Burges, Citation1994) implemented at 1/16 degree resolution. The CBCCSP also provided a complete and well-tested data processing sequence for post-processing and summarizing the hydrologic data to provide figures and analysis efficiently. However, our goal in this case was not to reduce the range of uncertainty by selecting a smaller group of GCMs. Sites without modified or natural flow estimates are shown in yellow. The first nine months of the dataset were used for hydrologic model spin-up, resulting in 91 water years (OctoberSeptember) of usable historical data from the hydrologic model simulations. The CBCCSP (and extensions over the west) has greatly reduced the costs of these types of studies by supplying (at essentially no cost) a wide range of high-quality hydrologic scenarios as a foundation for further work. The PET is shown to increase dramatically over most of the domain (primarily because of warming in the scenarios), whereas AET shows widespread declines east of the Cascade Range. Highs in the lower to mid 40s. Although results from the WACCIA would arguably have been adequate to support WDOE's adaptation planning, the CBCCSP provided additional foundation support for these efforts, and helped improve confidence in the outcomes of the adaptation strategies identified by better quantifying a range of outcomes. In relatively small basins (approximately 5001500km2), of which there are a substantial number included in the study, errors in meteorological driving data are often a strong determinant of simulation errors. Potential evapotranspiration increases over most of the PNW in summer because of rising temperatures; however, actual evapotranspiration is reduced in all but a few areas of the domain because evapotranspiration is mostly water limited in summer, and summer precipitation decreases in the simulations. Many river locations that were submitted for consideration were at gauging locations supported by the USGS and ECAN, or at locations associated with important water resources monitoring needs (e.g., checkpoints for flood control, water supply, or environmental flows) or infrastructure (e.g., dams and diversion points). Size, however, is only one aspect of what makes the river particularly unique. Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods. Figure 1. 'High Uncertainty' is indicated when Mahalanobis Distance is >1. Text files (six per figure) providing all the ensemble data used to construct each panel in the figure are also provided on the CBCCSP website. The PET increases over most of the PNW in summer as a result of rising temperatures; however, AET is reduced in all but a few areas of the domain because AET is water limited and summer precipitation decreases in the simulations.

The WDOE was also directed to incorporate climate change explicitly in these comprehensive assessment efforts. This is a good example of the use of the study data to support relatively fine-scale planning needs.

These emerging needs ultimately led to the CBCCSP, and similar efforts in BC led by PCIC (Werner, Schnorbus, Shrestha, & Eckstrand, Citation2013).
Climate Change Impacts on the Columbia Basin The HD method was also selected as the basis for the main summary products derived for each river location (see description below), primarily because it was capable of providing good performance over the complete range of products produced by the CBCCSP (Hamlet et al., 2010a). Naturalized or modified flow data were available at a number of locations in the PNW. Each of the six panels in the figure shows the long-term monthly mean for the 10 (9 for B1) HD GCM scenarios (red lines) and the historical simulations (blue lines).
