Köppen climate types in the Northwest Territories. The Northwest Territories extends for more than 1,300,000 km 2 (500,000 sq mi) and has a large climate variant from south to north. The southern part of the territory (most of the mainland portion) has a subarctic climate, while the islands and northern coast have a polar climate.
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are A (tropical), B (arid), C (temperate), D (continental), and E (polar).
Several methods have been used to define the subtropical climate depending on the climate system used. [ citation needed ] The most well known [ 3 ] is the Trewartha climate classification , which defines a subtropical region as one that has at least eight months with a mean temperature greater than 10 °C (50.0 °F) and at least one month with ...
It is measured as the mean of all annual temperatures, with all temperatures below freezing and above 30 °C adjusted to 0 °C, [4] as most plants are dormant at these temperatures. Holdridge's system uses biotemperature first, rather than the temperate latitude bias of Merriam 's life zones, and does not primarily consider elevation directly.
dwarf birch and Arctic willow are among the common shrub species, along with heaths, herbaceous plants, and lichens. Where nutrients and moisture are available along the rivers and streams, scattered clumps of stunted spruce trees grow. Sedges and mosses thrive in the wetlands of the lowland areas of this ecoregion and provide nesting sites for ...
