Climatology
The J-SCOPE forecast system for Washington and Oregon coastal waters forecasts sea-surface temperature (SST), chlorophyll stock, dissolved oxygen, and sardine habitat. The forecasts are composed of three ensemble members each relying on complementary forcing files from CFS. Forecasts are reported as anomalies - in other words, the forecasted fields differenced from a climatology, in order to provide context as to how "characteristic" the forecasted conditions are expected to be. For more information about anomalies, please see the NANOOS Climatology App. This climatology consists of an average of forecasted conditions from either the January or April initialized forecasts spanning 2009 to 2017 (N = 12 runs for each climatology). The reforecast climatology shown on this page will be used as the reference fields for the forecasted anomalies for all forecasts from 2018 onward. January initialized forecasts will use the January initialized reforecast climatology.
The model climatology spanning May - August for the upwelling season. More information about the three panels above can be found by navigating the Chlorophyll, SST, and Oxygen tabs above. The gray contour indicates the 200m isobath (shelf break) and the black contours on the bottom oxygen panel (left) indicate near hypoxic (1.5 ml/l) oxygen levels. The panel on the far right depicts the bottom water pH over the forecast period. The pH field is calculated using an empirical relationship established by Alin et al., in prep. This work is part of a collaboration between Samantha Siedlecki, J-SCOPE, and the Ocean Acidification group at NOAA PMEL.
