Dfb

Mild continental humid climate

DClo

Temperate continental climate with mild summer with cold winter

Traditional Koppen classification: Dfb (Mild continental humid climate)

Official definition:

D – temperature of the warmest month is higher than or equal to 10 °C and temperature of the coldest month is less than or equal to -3 °C.
f – precipitation is relatively evenly distributed throughout the year.
b - temperature of each of the four warmest months is higher than 10°C, but the temperature of the warmest month is less than 22 °C

In general it can be said that the D climate type can only be found in the Northern Hemisphere, northwards from the C climate zones, closer to the North Pole. The average temperature during the warmest month is higher than or equal to 10 °C, but in the winter the coldest month has an average value of less than -3 °C. In the winter it often snows and it tends to be quite windy and cold due to the polar and Arctic air masses.

Just like the Dfa type, precipitation is evenly distributed throughout the year. In comparison to the Dfa however, summer is slightly colder and the warmest month does not have average temperature above 22 °C. The highest summer temperatures are still usually between 30 and 35 °C, in the winter it drops to -10 to -35 °C.

Precipitation is higher in the summer, but the difference is not very large. Most of the precipitation in the summer occurs during thunderstorms and so quite often there are longer dry periods between them.

This Dfb category includes for example parts of Northern U.S. (for example Buffalo or Calgary), Southern part of Canada (for example Ottawa), Southern part of Russia (for example Vladivostok), Western part of Central Europe or Southern part of Scandinavia (for example Helsinki).

Modern Trewartha classification: DClo (Temperate continental climate with mild summer with cold winter)

In the Trewartha classification, the category D is like in the Koppen classification, assigned to regions in the temperate zone. The criterion for this type of climate is four to seven months with average temperature of more than 10 °C. In general it is further subdivided into two subtypes: oceanic and continental. These differ in their average temperature of the coldest month.

Temperate climate is characterized by four distinct seasons and there are substantial differences between the temperatures in the summer and in the winter, but the absolute values are not so extreme and the change is gradual.

The continental subtype is typical for regions located more inland and this also means the temperature variation is larger than that in case of the oceanic subtype. The coldest month has an average temperature of less than 0 °C. Summers are usually warmer, while winters colder with snow being quite common.

Continental D climate type can be found for example in parts of Northeast U.S., Central and Eastern Europe and usually these areas are quite densely inhabited.

mild summer: warmest month with average temperature between 10 and 18 °C
cold winter: coldest month with average temperature between -10 and 0 °C
