Climate In the southern arctic
Long, cold winters and short, cool summers characterize the Southern Arctic climate.
Winter temperatures range from -11°C to -7°C, while summer temperatures range from 4°C to 6°C.
The long hours of light and milder temperatures result in a longer growing season than the more northerly ecozones and, consequently, more vegetation is able to survive.
An annual mean precipitation of 20–50 cm also allows for the "greening" of this ecozone in the spring and summer.

Southern arctic landforms
The Southern Arctic is mostly plains. In many places, the rock of the Canadian Shield protrudes, forming hills.
When this ecozone was formed by glaciers, many depressions were carved in the land, and these were often left filled by ice from the glacier that carved it.
When the this ice melted, lakes were formed in the depressions.
The Southern Arctic ecozone is mostly covered in permafrost- permanently frozen ground.

Tundra, In The Southern Arctic Region.
The tundra environment is characterized by the general presence of PERMAFROST (except beneath some lakes and rivers) short summers with almost continuous daylight; long winters and arctic "nights"; low annual precipitation (hence the name polar desert) strong winds and winter blizzards.
