Study Notes

Type D Climates Overview

Type D climate, also known as humid microthermal or humid continental, features severe winters and is classified as a humid mid-latitude climate.

Geographic Distribution

D climates are exclusively found in the northern hemisphere, with no occurrence in the southern hemisphere.

Categories of D Climates

Dfs and Dfb signify the Humid Continental climate.
Dwa and Dwb are variations of Humid Continental only present in Asia.
Dfc and Dfd represent Subarctic climates.
Dwc and Dwd denote Subarctic climates found only in Asia.

Humid Continental Climate Locations

Dfa, Dfb, Dwa, and Dwb climates are located from the Midwest United States to the east coast, extending into southern Canada from the Plains to the east coast.

Humid Continental Climate Characteristics

Characterized by large annual temperature variations influenced mostly by continental polar (cP) air.
Experience low to moderate precipitation totals combined with low potential evapotranspiration (PET).
Dfb climate has no distinct dry season, while Dwa and Dwb climates have a marked winter dry season.

Mechanisms Influencing Humid Continental Climate

Positioned in far northern latitudes leading to lower solar radiation and negligible heat energy.
Strong continentality significantly affects climate, being distant from oceans.

Vegetation in Humid Continental Climate

Vegetation ranges from broadleaf deciduous trees in southern areas to mixed deciduous and needleleaf evergreens in central regions, and predominantly needleleaf evergreens in northern zones.

Subarctic Climate Locations

Dfc, Dfd, Dwc, and Dwd climates span west Alaska across Canada to Newfoundland, defining the Subarctic region.

Subarctic Climate Characteristics

Features long, harsh winters and the most significant annual temperature ranges among climates.
Dwc and Dwd varieties showcase a distinct winter dry season.

Example of Subarctic Temperature Range

Yakutsk, Russia exhibits a temperature range of 63 degrees Celsius (145 degrees Fahrenheit), illustrating the extreme variability typical of Subarctic climates.

Mechanisms Influencing Subarctic Climate

Characterized by high latitudes leading to minimal solar radiation.
Strong continentality also plays a critical role in subarctic climate dynamics.

Vegetation in Subarctic Climate

Dominated by needleleaf evergreens and Taiga forests, including a mix of spruce, fir, birch, and larch trees.
