Daily forecast of Columbia River plume: a tale of two cruises
Abstract
The Columbia River plume has a very dynamic and complex response to external forcings such as wind, freshwater discharge, and tides. In May and July 2004, the CORIE (http://www.ccalmr.ogi.edu/CORIE/) forecasting technology was used to provide daily predictions of baroclinic plume circulation in support of multi-vessel NOAA Fisheries and NSF RISE cruises. Model simulations were transferred real-time or daily to the vessels, and the results were contrasted against data from the CORIE real-time observation network and the Oregon State University coastal radar network, as well as against selected data from the vessels and (in May) airborne remote sensors. The forecasts proved effective in capturing major characteristics of the plume including its response to shifting winds. Post cruise simulations added quality to the quantitative characterization of the plume.
