Types of subantarctic climate according to the Köppen Classification - Dfc, Dwc, Dfd and Dwd. All species are characterized by wet cold readings. Detailed description below. Dfc - a short cool summer, a period with an average monthly temperature above 10 ° C less than 4 months; constant hydration throughout the year. Dwc - a short cool summer, a period with an average monthly temperature above 10 ° C less than 4 months; dry season in summer. Dfd - summer similar to “c”, very cold winter, average temperature of the coldest month -38˚С; constant hydration throughout the year. Dwd - summer similar to “s”, very cold winter, average temperature of the coldest month -38˚С; dry season in summer.
Feature
Over the oceans of the southern hemisphere south of 60˚ s. w. to the coast of Antarctica, the subpolar climate is characterized by a very uniform temperature distribution in summer, when the temperature in most of the water area is zero. But in winter it quickly decreases and reaches off the coast -20 -С and lower. In these latitudes, the centers of cyclones most often pass. Therefore, the cloudiness here is very great, as is the frequency of precipitation and fog. The prevailing westerly winds near the mainland are replaced by easterly.
