Information about Josko Bobanovic Josko Bobanovic Barotropic Circulation Variability on Canadian Atlantic Shelves Barotropic variability of the Canadian Atlantic Shelf on synoptic time-scales is examined using data analysis, statistical and dynamical models. The main objective is to understand the connections between the subregions and develop models that can be used operationally. Data are used to determine dominant scales, run statistical models and validate dynamical models.
Data assimilation is used to infer open boundary conditions for the dynamical models.
In the first study synoptic variability of the Labrador Shelf is examined using a limited area model. Wind and upstream boundary forcing are found to be the most important sources of the variability. Based on model results a forecasting scheme is designed and tested. The second subregional study concentrated on the variability in the Gulf of Saint Lawrence. Boundary forcing via Cabot Strait is found to be the dominant source of variability.
