| Abstract | This map shows the average maximum snow depth in centimetres computed over 18 winter seasons (1979 to 1997). Over southern Canada this usually occurs in January or February, while the time of maximum
accumulation occurs much later in mountain areas and in the Arctic. The main features of the map are the pronounced maximum in snow accumulation over the western Cordillera, where snow depths can exceed several metres, with a secondary maximum over
Quebec and Labrador. These maxima are related to their proximity to oceans, which act as sources of moisture and winter storms, and to the orographic effect of the mountains in the case of western Canada. The two maxima are linked by a band of higher
snow accumulation that follows the boreal forest zone; this is a preferred track for winter storms. To the north of this zone is the relatively shallow snow cover of the Arctic (low snowfall with extensive wind packing). To the south, the depth of
snow is limited by the shorter accumulation season and the substantial sublimation of snow over the Canadian Prairies. |
| Summary | (Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online
using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster
and made available in PDF and JPEG. |
