Cold Climate: Focus on Boreal Lands
Location
The word boreal means 'northern'
Stretch across the northern hemisphere between 50
N and the Artic Circle (661/2
N)
Climate
Is of cool continental type
Main Features
Very cold winters
These are high latitudes. The sun's rays reach them at oblique angles and give little heat
Short but warm summers
They get long hours of daylight. This causes the heat of the land to increase gradually
Light Precipitation
The polar winds are two cold to hold much moisture
Natural Vegetation
Coniferous trees
Evergreen
Features
Slender shape offers little resistance to wind and so reduces the risk of trees being blown over during storms
Thick bark retains moisture and protects the conifer from the cold dry winters
Thin, needle-like foliage is withered by cold, biting winds
Downward sloping and springy branches allow snow to slide of
Shallow roots can be develop in the thin layers of soil above the permafrost (permanently frozen ground)
