Projections - Climanalyse

In this section, we divided Canada in 4 specifics area to display climate projection. For each domaine and each Regional Climate Model from CORDEX-NAM44 , we calculated the interannual anomaly over 1971-2000 and 2011-2100 periods compared with normal 1971-2000. In future condition (2011-2100), we used 6 simulations with rcp4.5 scenario and 9 simulations with rcp8.5 scenario. In historical condition, we used 9 simulations.
We used the Second Generation of Homogenized Temperature dataset (Vincent and al. 2012). The interactive map bellow indicate Environnement Canada stations' position over Canada for each domaine delimited with red box.

The diagram shows the change in minimum and maximum temperature (°C) during the years 1971-2000 and 2011-2100 compared with normal 1971-2000. The bars historical homogenized temperature stations from Environment Canada. Red bars show temperatures above normal and the blue bars show temperatures below normal. The blue line shows the ensemble mean of 6 RCM (Regional Climate Model) with RCP4.5 scenario. The red line shows the ensemble mean of 9 RCM (Regional Climate Model) with RCP8.5 scenario. The grey line shows the ensemble mean of 9 RCM (Regional Climate Model) under historical condition.

Left panel present the relative change in total precipitation versus absolute change in temperature. Right panel present the relative change in precipitation intensity versus relative change in total precipitation .
