Pacific Northwest Hydrologic and Climate Change Scenarios for the 21st Century

A Brief Introduction to New Products and Overview of Downscaling Approaches

About the Webinar

Pacific Northwest (PNW) hydrology and water resources are projected to be considerably affected by a changing climate. These changes will have widespread impacts across a range of resource areas and planning horizons. Incorporating information about these changes into resource planning is an important component of adapting to climate change. This, in turn, requires access to climate impacts information produced at scales relevant to decision making.

Over the past 15 years, the Climate Impacts Group (CIG) has been a national leader in developing and applying statistical downscaling and dynamical regional climate modeling to provide fine scale climate impacts scenarios to PNW decision makers.

In spring 2010, the CIG will complete its most comprehensive downscaling effort to date with finalization of an unprecedented database of hydrologic climate change products for the Columbia River basin and selected coastal drainages in the PNW (see current draft of the database website, documentation, and products). These products are targeted for a broad user community, ranging from the general public needing summary information about impacts on specific watersheds to highly technical users requiring access to primary data resources for use in terrestrial and aquatic ecosystems research and water resources planning.

Part 1 of the webinar will familiarize participants with the objectives, methodology, and products that will be available through the Columbia Basin Climate Change Scenarios Project database. Part 2 will look more broadly at the roles of statistical downscaling and dynamical regional climate modeling in scenario development at the CIG, what the different approaches provide to end users, and potential tradeoffs in the choice of approaches. Future webinars and meetings related to these and other topics will also be discussed.

Webinar Schedule (back to top)

The webinars will be hosted on Wednesday, March 17 from 11:00 am - 12:00 pm and again on Wednesday, March 24, from 1:00 pm - 2:00 pm. All times are Pacific Time.

Who Should Participate (back to top)

The webinars are open to the public. Those involved in water resources, terrestrial, and aquatic ecosystems planning and research may be particularly interested.

How to Participate in the Webinar (back to top)

Participation in each webinar is limited to 100 callers. An RSVP is not required but is recommended. While the RSVP does not guarantee a spot in the webinar, it does help us know if we are getting close to that limit. Your RSVP also makes it possible for us to email you prior to the webinars with final details and other information.

To RSVP, please email Lara Whitely Binder stating which webinar you intend to participate in. There is no registration fee for either webinar.

To participate in the webinar, you only need access to a telephone and a web browser with Adobe Flash 8 or higher (note: If you can view YouTube videos, you have Adobe Flash and therefore can access the webinar). Adobe Flash is available as a free download if needed; no other software or applications are required to particpate.

More about the Climate Impacts Group (back to top)

The University of Washington Climate Impacts Group is an internationally recognized interdisciplinary research team studying the impacts of climate variability and climate change on PNW.  For the last 15 years, the CIG has conducted cutting-edge climate and climate impacts research at spatial scales ranging from local communities to the entire western U.S. Additionally, the CIG has created an extensive set of tools and scientific resources used by stakeholders, regulatory agencies, resource managers and policy makers in addressing PNW climate change impacts.  Key areas of the group's collective expertise include:

  • Development of gridded meteorological data sets
  • Statistical downscaling techniques
  • Regional climate modeling
  • Seasonal to interannual climate variability and forecasting
  • Macro scale and fine scale hydrologic modeling
  • Water resources modeling and impacts assessment
  • Terrestrial and aquatic ecosystem impacts assessment
  • Coastal impacts assessment
  • Climate change vulnerability assessment and adaptation planning
  • Outreach and education programs

The CIG currently provides a wide range of climate change products and services to PNW stakeholders using a suite of statistically downscaled climate model simulations from the IPCC Fourth Assessment Report (IPCC AR4). These products will continue to be updated as new global climate model simulations become available (e.g., IPCC AR5).

In addition to these well-proven approaches, over the last five years the CIG has also developed an innovative, comprehensive, and well-funded regional climate modeling program, which provides the foundation for the CIG's cutting-edge experimental downscaling research and high resolution output for use in climate impacts assessments for various natural resources around the PNW.
