  • Mean maximum depth of snow and time of occurrence

    The map shows the mean maximum depth of snow in centimetres, the standard deviation of the mean maximum depth of snow, and the mean date of mean maximum depth of snow. The information shown on the map is compiled from 1961 – 1970 snow course data in conjunction with 1955 – 1972 snow depth data....

  • Dates of formation and loss of snow cover

    The map shows isolines on four different dates: 1) the day of the year when there are less than or equal to 2.5 centimetres of snow that occurs and remain absent for 7 or more days; 2) the standard deviation of the mean date of snow cover loss; 3) the day of year when greater than or equal to 2.5...

  • Snowfall (Nunavut)

    Nunavut lies in the Arctic, where cold temperatures mean that snow can fall at anytime in the year. Typically the ground is snow covered from September until June. Most of Nunavut has a dry Arctic climate receiving less than 200 centimetres of snow annually.

  • January Mean Total Precipitation

    The map shows the mean total precipitation in the month of January. January precipitation across Canada is mainly in the form of snow. Throughout much of the interior and the north, precipitation amounts are generally less than 20 mm and, in the high Arctic, as little as a few millimetres. The...

  • Land Cover

    The map is based on satellite data obtained from the Advanced Very High Resolution Radiometre (AVHRR) on board the NOAA-14 satellite. Each land cover type can be identified by its unique spectral signature. Each signature is identified by a particular colour on the map. The land cover classes...

  • Annual snowfall

    The map shows the annual snowfall (in centimetres) based on the 30-year period 1941-1970. Snowfall is measured by inserting a ruler into the new snow at several points to obtain its depth and to estimate the degree of drifting or scouring that has occurred. The water equivalent of snowfall for...

  • Mean Annual Total Precipitation

    Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows two maps for the annual total precipitation. Annual precipitation is defined as the sum of rainfall and the assumed water equivalent of snowfall for a given year. A specific gravity of 0.1 for freshly fallen snow...
