Almonte, J. 2018: Precipitation transition regions over the southern Canadian Cordillera under a warming climate. MSc, University of Manitoba. Thesis

The future occurrence of various types of winter precipitation is an important issue over the southern Canadian Cordillera. This thesis examined this issue from January to April of 2010 by exploiting a high-resolution dataset provided by the National Center for Atmospheric Research using the Weather Research and Forecasting (WRF) model Version 3.4.1 to simulate both a historical reanalysis (CTRL) and a Pseudo-Global Warming (PGW) experiment. Changes to the transition region were consequently investigated under a warmer and more moist climate (Liu et al. 2016). Accumulated precipitation within the transition region increased by 27%. The rise in the average elevation led to an eastward shift towards the higher terrain of the Rocky Mountains. Transition regions comprised of rain and snow were most common under both the CTRL and PGW, although the proportion of rain increased which would form weaker snowpacks with a higher risk of avalanching.
