Diane is a research scientist with the Ocean Sciences division at the Institute of Ocean Sciences and who has been involved with the Strait of Georgia Ecosystem Research Initiative. As part of this project, Diane was involved in developing an application of the Regional Ocean Modeling System (ROMS) for the Strait of Georgia. This model is the ocean dynamics component of an end-to-end modeling system. The model is forced by freshwater inflow from major rivers, tidal forcing and seasonal climatology at open boundaries, as well as wind stress and heat flux at the ocean surface. The model is being developed to reproduce realistic circulation features and water properties (temperature and salinity) for the Straits of Georgia and Juan de Fuca over a typical seasonal cycle as well as to capture year to year variability. Because the model output is used to force a lower trophic model, simulating a realistic near surface stratification is a primary concern. As such, one needs to force the model with a realistic wind stress and new wind stress field were prepared using hourly data for 30 local wind observation stations. The measured wind stress vectors were interpolated onto the model grid using a thin plate radial basis function. Using the improved hourly wind stress, a yearly simulation was successfully completed for 2007.
