subpolar zone

Boreal climate, as classified by temperature or cold case is referred to as. Between a temperate and relatively high temperatures, and short summers and long winters are characterized by a severe cold. To the north of latitude 40 ° south of the Arctic tundra appears the northern region of Eurasia, North America is that. Except Antarctica and in the cooler areas of the rivers freeze and snow cover period, amounting to a few months time. However, a very short summer growing period is short crop cultivation. Due to the annual range of temperature, seasonal changes are distinct landscapes.
 May-June if the snow melts and the different kinds of flowers start to bloom, September and October, awning nakyeopsuna vegetation. In most areas of coniferous trees in a primeval forest called taiga in Siberia. Trees, crop growing period (average temperature 10 ℃ or higher) are distributed in less than four months. Some of the forest, such as foxes, martens, squirrels are many number of fur. Jujong constitute two of the hunting industry, forestry and agriculture is practiced.

1. cold with dry winter climate

2. humid continental climate

Dry climate

Trees can not grow due to lack of moisture of climate. Wet or dry of climate is  determined by difference between the amount of rainfall and the possibility of evaporation.

Prolonged lack of moisture in the forest land to grow well because it makes plain or a desert, dry, desert climate and grasslands, depending on the severity of the climate can be divided into:

In the arid region occupies about 30% of the total area, mainly under the control of mid-latitude high-pressure units in the distribution of the regression line close to the inside of a Central Asia and the North American continent north latitude 50. To have spread.

Typically, the summer temperature variability and the annual range of large and high daytime temperatures. Many irregular shape of the convective rainfall horyuga, and changes in precipitation are much larger than the wet climate.

The amount of rainfall is high in The low latitudes in the summer, and it is high in high latitudes in winter.
