The synoptic- and planetary-scale environments associated with significant 1000-hPa geostrophic wind events along the Beaufort Sea coast
The substantial interannual variability and the observed warming trend of the Beaufort Sea region are important motivators for the study of regional climate and weather there. In an attempt to further our understanding of strong wind events, which can drive sea ice dynamics and storm surges, their c...

The substantial interannual variability and the observed warming trend of the Beaufort Sea region are important motivators for the study of regional climate and weather there. In an attempt to further our understanding of strong wind events, which can drive sea ice dynamics and storm surges, their characteristic environments at the synoptic and planetary scales are defined and analysed using global reanalysis data. A dependency on an enhanced or suppressed Aleutian low is found. This produces either a strong southeasterly or northwesterly 1000-hPa geostrophic wind event. The characteristic mid-tropospheric patterns for these two distinct event types show similarities to the positive and negative Pacific/North American teleconnection patterns, but their correlations have yet to be assessed. L'étude du climat régional et du météorologie du Mer Beaufort est motivée par son variabilité interannuelle important et par la réchauffement qui y est observée. En essayant de comprendre les évenements à vents forts, qui peuvent forcer les dynamiques du glace marine et les ondes tempêtes, leurs environnements caractéristiques aux échelles synoptiques et planétaires sont définies et analysées en utilisant la donnée globale réanalysée. Une dépendance sur une dépression Aleutienne augmentée ou diminuée est trouvée. Ca produit un évenement à vents géostrophiques forts à 1000-hPa soit du soud-est soit du nord-ouest.
