Cfa

Humid subtropical climate

DOak

Temperate oceanic climate with hot summer with cool winter

Traditional Koppen classification: Cfa (Humid subtropical climate)

Official definition:

C – temperature of warmest month greater than or equal to 10 °C and temperature of coldest month less than 18 °C, but higher than -3 °C
f – precipitation is relatively evenly distributed throughout the year and do not fulfill classification criteria for s or w type
a - temperature of warmest month above 22 °C

The Cfa climate type is typical for areas on the Eastern coasts of continents, mostly between 20th and 30th latitude. The average temperature of the warmest month is higher than 22 °C and the temperature throughout the year range from usually -3 to 18 °C. In the winter, however, in some cases it can be well below freezing point.

Precipitation is relatively evenly distributed during the entire year. Humidity tends to be higher during the summer half year, when the conditions resemble the humid tropical climate. The total annual rainfall can be quite variable, most commonly between 650 and 2500 mm. Thunderstorms during the summer are frequent.

Cfa climate type can be found for example in the Southeastern USA, Northern part of Argentina, Uruguay and Southern part of Brazil, Southern Japan and South of China.

Modern Trewartha classification: DOak (Temperate oceanic climate with hot summer with cool 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.

In case of the oceanic type, winter is milder than that of the continental type and the temperature of the coldest month usually above 0 °C. The weather conditions are to a large extent influenced by the nearby ocean, which causes smaller temperature variation between the individual seasons. Typical is Western wind and so we often find this type of climate on Western coasts of continents, such as for example in Western Europe or Western coast of the U.S., in latitudes between 40 and 60 ° in America and 40 and 65 ° in Europe. These regions tend to be densely inhabited.

hot summer: warmest month with average temperature between 23 and 28 °C
cool winter: coldest month with average temperature between 0 and 10 °C
