Dynamical Downscaling of Temperature Variations over the Canadian Prairie Provinces under Climate Change

Dynamical Downscaling of Temperature Variations over the Canadian Prairie Provinces under Climate Change

In this study, variations of daily mean, maximum, and minimum temperature (expressed as <i>T<sub>mean</sub></i>, <i>T<sub>max</sub></i>, and <i>T<sub>min</sub></i>) over the Canadian Prairie Provinces were dynamically downscaled...

Dynamical Downscaling of Temperature Variations over the Canadian Prairie Provinces under Climate Change
description In this study, variations of daily mean, maximum, and minimum temperature (expressed as <i>T<sub>mean</sub></i>, <i>T<sub>max</sub></i>, and <i>T<sub>min</sub></i>) over the Canadian Prairie Provinces were dynamically downscaled through regional climate simulations. How the regional climate would increase in response to global warming was subsequently revealed. Specifically, the Regional Climatic Model (RegCM) was undertaken to downscale the boundary conditions of Geophysical Fluid Dynamics Laboratory Earth System Model Version 2M (GFDL-ESM2M) over the Prairie Provinces. Daily temperatures (i.e., <i>T<sub>mean</sub></i>, <i>T<sub>max</sub></i>, and <i>T<sub>min</sub></i>) were subsequently extracted from the historical and future climate simulations. Temperature variations in the two future periods (i.e., 2036 to 2065 and 2065 to 2095) are then investigated relative to the baseline period (i.e., 1985 to 2004). The spatial distributions of temperatures were analyzed to reveal the regional impacts of global warming on the provinces. The results indicated that the projected changes in the annual averages of daily temperatures would be amplified from the southwest in the Rocky Mountain area to the northeast in the prairie region.
