J-SCOPE forecast results for the model run beginning in April of 2019 are shown in the first figure. Each panel represents ensemble averaged anomalies of two month averages for the region. The panels directly under the anomaly plots depict the relative uncertainty from the ensemble for the same time periods.

For waters off the Washington and Oregon coast, the forecast projects that 10-meter integrated chlorophyll will be slightly lower than climatology on the shelf and higher than climatology farther offshore at the beginning of the upwelling season (May - June). However, later in the upwelling season (July - August), shallow shelf waters in Washington will have chlorophyll near climatology, while Oregon coastal waters and all offshore waters will have chlorophyll levels higher than climatology. The relative uncertainty is highest near the shelf break in May - June, but then decreases slightly for the remainder of the upwelling season (July - August).

The uncertainty is caused by the differences between the three ensemble members wind forcing, see California Current Indicators.
