Rainfall in the Canadian Arctic has increased by more than 20% in the last decades. However, the degree of rainfall increase is subject to variation from one location to the next. For example, in Resolute, Nunavut in the period of 1948 to 2007, there was a 48% increase in rainfall recorded with an average of 13.6 mm (0.54 in) of rain per decade.
Average summer temperatures range from 37 °F (3 °C) to 60 °F (16 °C). The tundra is very much like a desert in terms of precipitation. Yearly average precipitation varies by region, but generally, there is only about 6–10 inches (150–250 mm) of precipitation per year, and in some regions, it can have up to 20 inches (510 mm).
The climate of the ecoregion is Tundra climate (Köppen climate classification ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F). [7] [8]
This climate is characterized by mild summers (only 1-3 months above 10 °C (50.0 °F)) and cold, snowy winters (coldest month below −3 °C (26.6 °F)). [ 6 ] [ 7 ] Average precipitation ranges from 200 mm/year in the northwest to 500 mm/year in Quebec.
The climate of the ecoregion is Tundra climate (Köppen climate classification ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F).
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F ...
[5] [6] Temperatures in the region average 9 °C (48 °F) in the summer months, and −21.5 °C (−6.7 °F) in the winter. Average precipitation ranges from 300 mm/year in the low elevations in the north to 750 mm/year in the higher elevations of the Selwyn Mountains of the southeast.
A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2] In a tundra climate, even coniferous trees cannot grow, but other specialized plants such as the arctic poppy can grow. In an ice cap climate, no plants can ...
