Annual relative precipitation trend shows that precipitation has been increased during the 1900-2004 period across most of the region. Historical trends show only how climate has changed during the specified period in the past. For example, the trend from 1950 differs considerably from the trend for 1900-2004. Finally, trends should not be extended into the future - see projections for information on future climate.","Data: CANGRID (50 km), Meteorological Service of Canada<br>Adapted from Zhang et al. 2000.<br>Analysis: PCIC staff<br>Support: BC Hydro and BC Ministry of Environment","ATLIN_TRENDS_TEMP50k.jpg", "ATLIN_TRENDS_PREC50k.jpg"),

The projected temperature increase is generally larger from south to north in the winter. Projected changes in annual precipitation by 2050s are shown as % differences from 1961-1990 baseline climatology. These relative increases are among the largest projected for western Canada. Projected changes in spring snow water equivalent (SWE) by 2050s are shown as % differences from 1961-1990 baseline climatology. Decreases are apparent at some locations due to increased temperatures. At high elevation and more northerly latitudes (locations with the coldest winter temperatures), increased snowpack is projected despite warming due to increased precipitation. Results are from a single Regional Climate Model (RCM) projection on a 45 km grid. The map illustrates one plausible future temperature change by the 2050s, but must be considered in combination with a range of projections (see subsequent pages).","Climate modelling: The Canadian Regional Climate Model version 4.1.1 (CRCM4) was developed by the Ouranos Consortium in collaboration with the Canadian Centre for Climate Modelling and Analysis (Environment Canada).<br>RCM data: provided by the Ouranos Climate Simulations Team for runs acs and act forced with CGCM3 following the A2 emissions scenario run 4.<br>Analysis: PCIC staff<br>Support: BC Hydro and BC Ministry of Environment","ATLIN_RCM_TEMP.jpg","ATLIN_RCM_PREC.jpg","ATLIN_RCM_SNOW.jpg"),
