Snow cover naturally varies with temperature, precipitation and climate cycles, such as El Niño. Information on snow quantities and snow cover duration is important for understanding how climate change is influencing snow cover in Canada.
Apr 3, 2023 · Notarnicola's research shows a decrease of around 3.6 per cent in yearly snow cover, and an average drop in 15 days for snow cover duration globally.
The indicators show how Canada's snow cover is changing from year-to-year and over time. The indicators report spring snow cover extent and annual snow cover duration. Snow cover extent is expressed in millions of square kilometres and is presented for the spring months of April, May and June.
This article examines the average area covered by snow (snow cover extent) nationally for the 39 year period from 1972 to 2010. Snow cover extent is examined annually and for the months of October and November, the period that marks the onset and expansion of snow cover for much of Canada, and April, May, and June, the spring snow melt period ...
According to the satellite data used to generate Figure 1, on average ~65% of Canadian land area is snow covered for more than half the year, which means that snow cover is the dominant land cover in Canada.
Jul 3, 2022 · Environment and Climate Change Canada provides a snapshot of the current, daily snow conditions in the context of historical averages. Updated daily, this snow anomaly tracking displays a map of spatial snow depth anomalies and six time series of snow cover extent and snow water equivalence.
SNOW COVER. The portion of the year with snow cover decreased across most of Canada (very high confidence 1) as did the seasonal snow accumulation (medium confidence). Snow cover fraction decreased between 5% and 10% per decade since 1981 due to later snow onset and earlier spring melt.
