Subarctic Climate

A good day to all :) In the past lessons we've learned about Dry, Temperate and Continental Climates. So for today we'll move on and know about the:

"SUBARCTIC CLIMATE"

  • Subarctic Climate is also known as subpolar climate, subalpine climate, or boreal climate.

  • It is a climate characterised by long, usually very cold winters, and short, cool to mild summers.

  • It is found on large landmasses, away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N poleward of the humid continental climates.

PRECIPITATION:

  • Subarctic climates experience minuscule precipitation not more than 15 inches annually.

  • Much of the precipitation occurs along the coastline during autumn while other areas experience precipitation during the warmer months.

  • Low precipitation is experienced in more temperate regions with warmer winter and longer summers.

  • The coast of Khabarovsk Krai also receives precipitation of up to 6.9 inches in July.

  • Labrador in eastern Canada experiences high precipitation throughout the year and can receive an annual rainfall of 51 inches due to the Icelandic Low.

VEGETATION:

  • The subarctic climatic region has a low diversity of vegetation since only limited species of plants can survive the climate.

  • Hardy species dominate the region due to their ability to survive long winters and short summers.

  • Conifers are the majority trees in the taiga forests that characterize the subarctic regions.

  • The soil fertility and weather patterns make agriculture impossible.

  • Prevalence of lakes, swamps, and water bodies due to the departing ice sheets means plants cannot acclimatize. However, the summer permits some agriculture.

DISTRIBUTION:

  • The subarctic climate falls under the Köppen climate classification Dfc, Dwc, Dsc, Dfd, Dwd and Dsd.

  • The Dsc subarctic climate is found in higher altitudes of the Mediterranean Basin stretching from Iran, Kyrgyzstan, Tajikistan Turkey, and Alaska

  • It is also found in parts of the United States including Eastern Oregon, Eastern Washington, Idaho. The Dfc climate is the most common of the subarctic climate.

That's all for this blog. Thankyou! :)
