modeling team’s Phase II tasks.
Animation of Chlorophyll concentration from low-resolution (LR) and high-resolution (HR) models during 1987
Note: HR data is only available till 1991 but that for LR is available till 2020. The mid-March to mid-November period shows very fine-scale features in the HR case.
Chlorophyll concentration from LR case in a different projection. These type of plots/movies will help to demonstrate that the model is a global model, without the typical drawbacks of regional models (eg. EcoCAST).
This Animation shows the capability of our HR configuration in resolving near-coastal fine scale processes. The sea surface temperature (SST) in the first panel is cooler near the coast during the upwelling season (May-Sep).
A view of the anomalies in model fields during 2014-2015 Marine Heat Wave (the blob). Monthly data is used here.
SST field clearly shows the warm anomalies associated with the blob (compare 2014-Sep with that in here).
Low-resolution model is not able to reproduce fine-scale features in chlorophyll distribution and mechanisms that control them.
Note: There are differences between how these two versions of the models are set-up and run. So this is not an apples-to-apple comparison.

Upwelling index prediction for the California Current System
Vertical velocity at the 50 m depth level is taken as the Upwelling index.
