Subarctic [SEP] Introduction
The subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic and covering much of Alaska, Canada, Iceland, the north of Scandinavia, Siberia, the Shetland Islands, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is low, and vegetation is characteristic of the taiga. Daylight at these latitudes are quite extreme between summer and winter. Near the summer solstice for instance, subarctic regions experience an all night period of either civil, nautical, or astronomical twilight, since the sun never dips more than 18 degrees below the horizon.
