dc.description.abstractTwo articles recently published in the peer reviewed literature examine two types of extreme weather events that affect coastal British Columbia, storm surge events and atmospheric river events. The first paper, by Soontiens et al. (2016) in Atmosphere-Ocean examines the ability of a numerical ocean model to simulate storm surges in the Strait of Georgia and the relative contribution of several factors to storm surge amplitude in the region. The authors use the model to simulate six storm surge events from the 2006-2012 period at four locations and find that the model does well at reproducing the magnitude of storm surges. They also find that the primary contribution to storm surges in the region are sea surface height anomalies from the Pacific, with local wind patterns causing small spatial differences in the sea surface height. The second paper, by Hagos et al. (2016) in Geophysical Research Letters uses output from a global climate model to examine changes to atmospheric river events over western North America, assuming large, business-as-usual anthropogenic greenhouse gas emissions. The authors' projections show an increase of about 35% in days on which atmospheric rivers make landfall in the last 20 years of the 21st century when compared to the last 20 years of the 20th century. Their projections also show a resulting increase of about 28% in extreme precipitation days.
