Improving the accuracy of the short-term ice and ocean forecasts in the Beaufort Sea : Améliorer l'exactitude des prévisions sur les océans et les glaces à court terme dans la mer de Beaufort

25 Feb 2016

The accuracy of sea-ice forecasting is evaluated by comparing the forecasts with the results of persistence of the initial analyses. [...] The project work plans includes - Improving the representation of ice with more advanced sea-ice models and improving the ocean model; - Constraining the sea-ice forecasts through the assimilation of satellite observations and CIS manual ice analyses as well as in situ ice observations; - Implementing an advanced ocean data assimilation system into the forecasting system; combining ocean and sea-i [...] Because the Beaufort is open to the Arctic Ocean, the presentation also includes the assessment of model performance over the entire Arctic. [...] The VVL makes the model stable even if the absolute value of negative SSH is larger than the thickness of the top layer, in fact, as long as it is less than the local water depth. [...] There is good agreement in terms of the distribution of liquid freshwater, with the greatest concentration in the Beaufort Gyre, but the total modelled freshwater content in the gyre is greater than in the climatology.
