Research Project: Understanding Extreme Precipitation Behaviour in British Columbia's Lower Mainland Using Historical and Proxy Data
Christie is a member of the Climate, Oceans and Paleo-Environments Laboratory in the School of Resource and Environmental Management. Her research focuses on the management implications of Pineapple Express storms, a subtropical winter storm that makes landfall on the west coast of North America on average of 0-4 times per year. The intense precipitation associated with these storms often leads to flooding, debris flows and water quality issues in Metro Vancouver. These impacts can be extremely hazardous and expensive, so they are of special interest to environmental managers, especially those dealing with public safety, land use planning, water quality and water supply. The goal of Christie’s research is to characterize Pineapple Express storms in terms of their historical trends (frequency, magnitude), defining characteristics (meteorological, hydrological and isotopic signature), and impacts, with particular emphasis on the Metro Vancouver area. She is also investigating ways to extend the existing chronology of Pineapple Express storm events, using oxygen isotopes in tree rings as proxy data. Christie was born and raised in Ottawa, Ontario and received her B.Sc. in Earth Sciences from St. Francis Xavier University in 2008.
