columbia basin climate

The Assessment will result in a better understanding the potential impacts of climate change on the eight components identified in SECURE in the Columbia River Basin. Dave Rodenhuis, Markus Schnorbus, Arelia Werner, and Katrina Bennett at PCIC at the University of Victoria, British Columbia, also provided in-kind support and funding for collaborative research which contributed materially to this project. Flooding in these basins is sensitive to both warming (which raises snow lines and effectively enlarges the contributing basin area during most flood events) and increasing winter precipitation. Thus, by selecting 10 GCM scenarios with good historical performance that also spanned the range of impacts, we effectively reduced the computational and storage requirements of the CBCCSP by approximately a factor of two. A comprehensive assessment of hydrologic extremes such as Q100 and 7Q10. How essential is hydrologic model calibration to seasonal streamflow forecasting? Following the WACCIA in 2009, the WA Legislature, via the Act relating to State Agency Climate Leadership (2009), charged WDOE and other state agencies with preparing a first climate change adaptation plan for WA. These emerging needs ultimately led to the CBCCSP, and similar efforts in BC led by PCIC (Werner, Schnorbus, Shrestha, & Eckstrand, Citation2013). What Makes The Columbia River Basin Unique and How We Benefit 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. This is likely because soil moisture is higher in summer west of the Cascade Range and evapotranspiration is mostly energy limited, whereas east of the mountains the late summer soil moisture is already very low in the current climate and increasing evapotranspiration does not result in much additional soil moisture stress.

YAKIMA Lower Columbia returned to the diamond on Friday with a double-header split against Yakima Valley. Communities across the region and around the world are demonstrating that its possible to adapt, to reduce greenhouse gas emissions, and continue to thrive. 135 0 obj <>stream 1990 level modified streamflow 19281989. Flooding in the Columbia River basin expected to increase under climate Citation2000) were selected as the basis for the study because they provide a) a wide range of plausible outcomes while also reflecting some potential GHG mitigation by the end of the twenty-first century, and b) most of the approximately 20 GCM projections associated with the CMIP3 archived runs from both emission scenarios (Mote & Salath, Citation2010). Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. Crook, A. G. (1993). About 15 sites in western Washington, outside the CRB, were also included in support of the 2009 WACCIA. The Columbia Basin-Boundary region is already experiencing a climate thats different from 50 years ago. Since 2014, the RDI has engaged in applied research related to community climate adaptation. Elsner et al. (For example, Dworshak and Milner are nested within the larger Ice Harbor sub-basin.). 8 Monthly mean hydrographs not adjusted for bias (water year: OctoberSeptember) for four representative river sites in the PNW: Kootenay River at Corra Linn Dam (upper left), Columbia River at The Dalles, Oregon (upper right), Yakima River at Parker (lower left), and the Chehalis River at Grand Mound (lower right). We used 50 parameter sets to define the initial optimization parameter space, of which the 25 best parameter sets advance in each evolution of the optimization. Climate Change Challenge In The Columbia River Basin: Managing Water endstream endobj 96 0 obj <. Three statistical downscaling approaches were selected or developed for the study: Composite Delta (CD): regional average projections compiled from 10 GCMs (Elsner et al., Citation2010), Bias Correction and Spatial Downscaling (BCSD): (Salath, Citation2005; Salath, Mote, & Wiley, Citation2007; Wood, Leung, Sridhar, & Lettenmaier, Citation2004; Wood, Maurer, Kumar, & Lettenmaier, Citation2002), Hybrid Delta (HD): (Hamlet et al., 2010a). The six panels display results from the combination of three time periods (rows) and two emissions scenarios (columns) used in the HD downscaling process. 0 O weather.com oferece para voc a previso do tempo mais precisa para Guarant do Norte, Mato Grosso com mdias/recordes e temperaturas mximas/mnimas, precipitaes e muito mais.

The methods are discussed in more detail in these references, but a brief description of the procedure is given here to help orient the reader. The summary figures for water balance variables at each site have the same format, two examples of which are shown in Fig. 12). 'High Uncertainty' is indicated when Mahalanobis Distance is >1. Fig. Columbia Basin Care is the region's only independent nonprofit skilled nursing facility for long-term care and short-term rehabilitation. Precipitation Regression on Independent Slopes Model (Daly et al., Extreme daily high flow value with a 20-year recurrence interval (20-year flood), Extreme daily high flow value with a 50-year recurrence interval (50-year flood), Extreme daily high flow value with a 100-year recurrence interval (100-year flood), River Management Joint Operating Committee. Until recently, a climate-change induced shift in water supply was the story of the Columbia River Basin's future. Open File Report SW 02-002. As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. Friday Mostly sunny. These products are available for all 77 climate scenarios listed in Table 1, as well as for the historical simulation. These spatial variations in the change in AET are broadly reflective of the dominant drivers of AET in each case. 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. These include the following: Columbia River Basin Impact Assessment: Reclamation conducted the Columbia River Basin Impact Assessment to evaluate the potential effects of future climate change on river flows at 158 locations across the basin. The Columbia Basin-Boundary region is already experiencing a climate that's different from 50 years ago. Nakienovi, N., Alcamo, J., Davis, G., De Vries, B., Fenhann, J., Gaffin, S.,Dadi, Z. Southwest wind 5 to 15 mph with gusts to around 25 mph. . Yakima River Basin Study Associated shifts in streamflow timing from spring and summer to winter are also evident in basins that currently have significant snow accumulation in winter, whereas rain-dominant basins show minimal shifts in streamflow timing. Although not as extreme as A1FI, the high-end A2 scenario was archived by most GCMs and could have been used in the CBCCSP in place of the A1B scenario. Incidence of Bactericera cockerelli (Hemiptera: Triozidae) under different pesticide regimes in the lower Columbia basin. Thursday Sunny. The CBCCSP was designed from the outset to support users with a very wide range of technical sophistication and capacity. Small black dots indicate streamflow sites where naturalized flows were not available. 9 Left panel: Historical estimates of summer (JJA) potential evapotranspiration (PET) (based on PET3, see Table 2) (upper right) compared with percentage changes in PET for two emissions scenarios and three future time periods from the CD scenarios. The CBCCSP provided climate change projections of meteorological drivers and a calibrated VIC implementation in support of the study. .. slide 2 of 5. The VIC implementations make use of preprocessed soil and vegetation databases for the basin of interest. Multi-Objective Complex Evolution Procedure, developed at the University of Arizona (Yapo et al., A water resources simulation model developed by Labadie (, National Centers for Environmental Prediction, Pacific Climate Impacts Consortium, University of Victoria. Instead, these areas respond primarily to projected changes in precipitation until late in the twenty-first century, and in fact some of these areas show modest increases in SWE (about +5%) until the middle of the twenty-first century under the combined effects of warming and increasing cool season precipitation. #! O Starting from these parameter sets, an additional large-scale calibration was performed during the CBCCSP to improve model performance in reproducing historical streamflow. La base de donnes du CBCCSP s'est avre une ressource publique prcieuse qui a permis de rduire normment les cots lis un certain nombre dtudes de haute visibilit dans la rgion pacifique nordouest et dans l'ouest des tatsUnis axes sur la coordination technique et la planification. The top two panels show the Nash Sutcliffe Efficiency (NSE) (left) and R 2 (right) for the calibration period, while the two lower panels show NSE (left) and R 2 (right) for the validation period. West-wide studies to support USFS and USFWS needs (including current efforts to include California) will have a budget of less than half this amount, a level of efficiency that would not have been achievable without the CBCCSP pilot effort. The site at Corra Linn Dam on the Kootenay River is representative of changing hydrographs in many locations in the northern tip of the CRB in British Columbia. Both calibration and validation periods were chosen to test model performance over a wide range of climate and streamflow conditions.

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). One of the fundamental difficulties with this task was that there was not, at the time, an available database of hydrologic projections that could support such planning, and regulatory agencies such as WDOE did not have the capacity or expertise to produce these resources themselves.

Blue dots represent the historical values; the red dots show the range of values from the HD ensemble (10 or 9 values); black dashes show the mean of the HD ensemble, and the orange dots show the single value calculated for the CD projections. Peak flows actually increase at many sites in Canada because of increasing fall, winter, and spring precipitation in this part of the domain, although the peak flow also occurs about a month earlier. 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. The Climate of the Columbia Plateau in Washington State Les plus fortes augmentations dans les crues sont dans les bassins de pluie et neige mles dont les tempratures actuelles au milieu de l'hiver sont quelques degrs du point de conglation. 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. The regional report for the National Assessment was supported by two detailed water management studies focused on the CRB by Hamlet and Lettenmaier (Citation1999b) and Miles, Snover, Hamlet, Callahan and Fluharty (Citation2000). By the end of the twenty-first century, essentially the entire state is classified as rain-dominant for the A1B scenario, and the B1 scenario is only slightly different (Fig. The CBCCSP was developed to address these diverse needs. Highs in the lower 80s. (unpublished manuscript). An understanding of the basin's transboundary nature has also informed CIG's hydrologic modelling studies, which have consistently provided complete coverage of the Canadian and US portions of the basin. Strong bias in the simulations is commonly caused by precipitation errors (too much or too little annual precipitation), or in some cases by substantial errors in base flows because of contributions from groundwater in the actual system, which are not simulated by the VIC model (Wenger, Luce, Hamlet, Isaak, & Neville, Citation2010). Originating in British Columbia, it flows 1,214 miles to the Pacific Ocean near Astoria, Oregon.

Act relating to state agency climate leadership, S. 5560, 61st Legislature (WA 2009). Current weather in Queens Cup Basin and forecast for today, tomorrow, and next 14 days These basins experience dramatic losses of snowpack and substantial changes in seasonal flow timing (Fig. Colombia - Climate | Britannica This study represents one of the first attempts to dynamically couple a sophisticated, physically based hydrologic model with a detailed crop model to estimate the integrated impacts on water supply and crop viability at a range of spatial scales. Snover, A. K., Hamlet, A. F., Lee, S.-Y., Mantua, N. J., Salath, E. P. Jr, Steed, R., & Tohver, I. A primary focus of the Assessment is to generate future climate change flow at more than 300 locations across the Columbia River Basin (Basin) and evaluated the potential impact of those flows at specific sub-basins within the Basin. Clima em Guarant do Norte, Mato Grosso - weather.com A calibrated 1/16 degree latitude-longitude resolution implementation of the VIC hydrologic model over the Columbia River basin was used to produce historical simulations and 77 future hydrologic projections associated with three different statistical downscaling methods and three future time periods (2020s, 2040s, and 2080s).

Other climate change studies on the Columbia River and its sub-basins followed (Cohen, Miller, Hamlet, & Avis, Citation2000; Elsner et al., Citation2010; Hamlet, Citation2003, Citation2011; Hamlet, Lee, Mickelson, & Elsner, Citation2010b; Lee, Fitzgerald, Hamlet, & Burges, Citation2011; Lee, Hamlet, Fitzgerald, & Burges, Citation2009; NWPCC, Citation2005; Payne, Wood, Hamlet, Palmer, & Lettenmaier, Citation2004; Snover, Hamlet, & Lettenmaier, Citation2003; Vano et al., Citation2010). Daily and monthly average streamflow for all projections listed in Table 1 and, where possible, daily and monthly bias-corrected streamflow values. Casola, J. H., Kay, J. E., Snover, A. K., Norheim, R. A., Binder, L. C. W., & the Climate Impacts Group. The CBCCSP, in particular, provided access to additional scenarios and downscaling methods that provided a range of hydrologic outcomes associated with uncertainty in the climate projections, which the WACCIA assessments largely did not. 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. About 10 locations show negative NSE scores, which usually occurs when the simulations are strongly biased in comparison with observations. The WDOE was also directed to incorporate climate change explicitly in these comprehensive assessment efforts. The Columbia River is the fourth largest river in North America. Even with substantial cuts to greenhouse gas emissions, scientists expect our climate to continue changing over the coming decades. What Does Climate Change Mean for Flooding in the Columbia River Basin Results from the study show profound changes in spring snowpack and fundamental shifts from snow and mixed-rain-and-snow to rain-dominant behaviour across most of the domain. The CIG (http://cses.washington.edu/cig/; see the Table of Acronyms in the Appendix) is an interdisciplinary research group at the UW focused on climate-related research in five major sectors: atmospheric sciences, hydrology and water resources, aquatic ecosystems, forests, and coasts. These approaches were further developed and refined during the WACCIA in 2009 (Miles, Elsner, Littell, Binder, & Lettenmaier, Citation2010), which included assessments of aquatic and forest ecosystem impacts (Littell et al., Citation2010; Mantua, Tohver, & Hamlet, Citation2010). The Columbia River is the fourth largest river in North America and the largest river in the Pacific Northwest. (Citation2010). Highs in the lower to mid 40s. The primary activities and objectives of the RMJOC studies are described in the Executive Summary of the project report (US Department of the Interior, Citation2012): The Bonneville Power Administration (BPA), U.S. Army Corps of Engineers (USACE), and U.S. Bureau of Reclamation (Reclamation) collaborated to adopt climate change and hydrology datasets for their longer-term planning activities in the ColumbiaSnake River Basin (CSRB). In other words, dry areas east of the Cascade Range have less base-flow potential to lose with increasing evapotranspiration and loss of summer precipitation because the soil moisture is already at very low levels in late summer. Because both these effects increase flood risk in the simulations, the effects are unusually large in these basins (Fig. The PRISM data for Canada were interpolated to 30 arc-second resolution data from a 2.5 arc-minute (approximately 4km) product and were statistically adjusted to remove the bias associated with the different time period (19611990 means for the 4km product). hbbd```b``z"I09 D.^`,L,=`v0fI" IA$C(QDrML@a`ig c Regional summaries were prepared by Tohver et al.

A set of simpler, lumped-storage reservoir operations models was used to quantify impacts in a number of smaller water supply systems. PDF Chapter 4: Columbia River Basin - usbr.gov Isaak DJ et al. Climate change effects on stream and river temperatures across the Northwest U.S. from 1980 - 2009 and implications for salmonid fishes. Demand factored into Columbia River Basin's future - WSU Insider The NSE scores for about 20 sites are marginal (between 0.3 and 0.7). A family of greenhouse gas emissions scenarios used in the IPCC effort (Nakienovi et al. Rain dominant basins (DJF temperatures greater than 2C) show moderate increases in flood risk (primarily reflecting increasing storm intensity in the simulations), whereas snowmelt-dominant basins that currently flood in June show relatively little change in flood risk. The Red Devils dropped the first game of the double-header 11-3 in five innings before . 2012. The largest increases in flooding are in mixed-rain-and-snow basins whose current mid-winter temperatures are within a few degrees of freezing. 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). 2860, 59th Legislature (WA 2006). How do I view content? 8) experience little change in the shape of the monthly hydrograph because there is only occasional low-elevation snow in mid-winter in the twentieth century base case; therefore, there is relatively little sensitivity of monthly runoff timing to warming. In the first five years (19952000) of operation, the research efforts of CIG were primarily directed towards the assessment of the impacts of interannual and interdecadal climate variability associated with ENSO (Battisti & Sarachik, Citation1995; Trenberth, Citation1997) and the PDO (Gershunov & Barnett, Citation1998; Mantua, Hare, Zhang, Wallace, & Francis, Citation1997). 6. To select an appropriate group of specific streamflow locations to include in the study to meet these diverse needs, the primary funding agencies for the study and several other key water management agencies in the region (MDNR, IDWR, USBR, and USACE) were asked to submit prioritized lists of streamflow locations. Bias adjustment was also used in preparing the specific reservoir modelling support products discussed below. 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. Oregon Water Resources Department. Over the last several years, the USFS and USFWS have engaged with the CIG to produce a set of initial climate change hydrologic scenarios over much of the west using a common methodology intended to support landscape-scale assessment of climate change impacts (Littell et al., Citation2011). A 20 percent chance of rain showers in the evening. Prior climate change datasets for the CRB produced by CIG (using CMIP2/TAR projections) only included about 20 river sites (e.g., NWPCC, Citation2005; Snover et al., Citation2003) and provided very limited support for planning efforts at smaller spatial scales. Either naturalized or modified flows (Crook, Citation1993) are used for bias correction of data provided in the site-specific products discussed below, with naturalized data taking precedence if available.
