Large-scale atmospheric circulation patterns appearing over the Atlantic Ocean (such as the Artic Oscillation or the North Atlantic Oscillation) affect climate variability in North America and in Europe. As tree growth is mainly controlled by climatic factors, ACPs might significantly affect the growth dynamics of boreal forests across the Atlantic region. So what if the large-scale feature of ACPs was driving the occurrence of teleconnections in growth dynamics of boreal forests within and between Quebec and Scandinavia?
Using ring width data of two boreal tree species (pine and spruce), my project aims at answering 3 questions:
(1) Are there any regional and transnational teleconnections in tree growth dynamics of boreal forests bordering the Atlantic Ocean and are these teleconnections correlated to atmospheric circulation patterns?
(2) What are the principal climatic drivers of basal area increment variations during periods of teleconnections and non-teleconnections?
(3) Can we improve tree growth modelling using regional and transnational teleconnections and their associated climatic drivers?
The project involves sampling of tree-ring data both in Quebec and Scandinavia.
