Short summary
Our research has analyzed the surface water budget and atmospheric water vapour budget over western Canada from a set of convection-permitting regional climate simulations. The pseudo-global-warming simulation shows a great increase in evapotranspiration and an enhanced water cycle. We found that the orographic effect on the water vapour budget is significant over the Saskatchewan River basin, indicating the need for high-resolution regional climate modelling to reflect the effects.
