Humidsubtropiske

Humid subtropical climate, known as humid subtropiske in Danish, is a temperate climate type in the Köppen classification. It is characterized by hot, humid summers and mild to cool winters. Precipitation occurs throughout the year in many areas, with a tendency toward higher humidity and frequent summer thunderstorms. Some regions with monsoon influence have a dry winter period, which corresponds to the Cwa subcategory, while others have no distinct dry season (Cfa).

Geographic distribution includes parts of the eastern United States, southeastern South America (notably parts of Argentina and Uruguay), southern China and parts of Japan, as well as coastal eastern Australia. The climate is most pronounced in low- to mid-latitude coastal regions where warm air masses interact with humid air, producing regular rainfall and lush vegetation. Winter temperatures are typically above freezing, though inland or high-altitude areas can experience cooler conditions.

Climate characteristics often feature long, hot summers with high heat and humidity, and winters that are mild by temperate standards. Average temperatures in summer commonly exceed 25°C, while winter averages are frequently above 0°C but can be cool. Annual precipitation ranges broadly, commonly between 700 and 1500 millimeters, with higher totals in summer for many monsoon-influenced zones. Snow and severe frosts are uncommon in coastal areas but can occur inland or at higher elevations.

Ecology and land use reflect the climate’s warmth and moisture. Vegetation includes broadleaf deciduous and evergreen forests, as well as subtropical woodland. The climate supports crops such as rice, citrus fruits, tea, and various vegetables, along with diversified forestry and urban development.
