Subarctic rainy climate - Akantaitauikikou

Japanese: 亜寒帯多雨気候 - あかんたいたうきこう

The subarctic zone is located between the temperate and polar zones, and lies in the latitude range of about 50 to 70 degrees, centered around where the westerly winds and the circumpolar winds (extremely easterly winds) meet. As a result, a polar front (polar front) forms between the two wind systems, and the subarctic zone has relatively high rainfall for a high latitude zone. Unlike the subarctic rainy summer climate of eastern Siberia, which has a lot of rain in the summer and dry winters, the subarctic zone has rainfall almost evenly throughout the year, but it is less than the temperate zone. The winters are harsh, with an average temperature of less than -3°C, and the summers are short but can exceed 20°C, making it possible to grow crops, and annual crop farming is practiced for spring wheat, rye, potatoes, soybeans, and sorghum.

Japanese:

亜寒帯とは温帯と寒帯の間に位置し，偏西風と周極風(極偏東風)の両者が出会うあたりを中心に，緯度にして大体50～70゜の範囲である。したがって，両風系間に寒帯前線(極前線)ができ，高緯度帯としては相対的に降雨の多い気候帯となっている。シベリア東部のように夏に雨が多く冬に乾燥するタイプの亜寒帯夏雨気候と異なり，年中ほぼ平均的に降雨がみられるが，温帯にくらべると少ない。冬の寒さは平均－3℃未満と厳しく，夏は短いが20℃を超えることもあり，作物生育が可能で，春小麦，ライ麦，ジャガイモ，大豆，コーリャンなどの一年一作型農業が行われている。
