Rainfall

Low and irregular precipitation, less than 200 mm per year.

Vegetation

Scarce vegetation, primarily found in oases.

Oceanic Climate

Location

Temperature

Moderate average temperatures, between 10°C and 15°C. Mild climate.

Temperature Range

Moderate thermal amplitude, typically between 10°C and 15°C. Mild/cool winters and cool summers.

Rainfall

High average precipitation, more than 800 mm per year. Regular rainfall, often with a peak in autumn.

Vegetation

Deciduous forest.

Mediterranean Climate

Location

  • California
  • Río de la Plata Basin (Argentina)
  • Western Australia
  • Circum-Mediterranean regions

Temperature

Moderate average temperatures, between 10°C and 15°C. Mild climate.

Temperature Range

Moderate to large thermal amplitude, between 15°C and 20°C. Mild winters and hot summers.

Rainfall

Moderate average precipitation, from 300 to 800 mm per year. Irregular rainfall pattern with dry summers. Potential for heavy rainfall events ('cold drops') in spring and autumn.

Vegetation

Evergreen forests, thickets (maquis, chaparral), steppe.

Continental Climate

Location

  • Interior of continents in temperate latitudes
  • Russia/Siberia
  • Central Canada
  • Northern China and Mongolia

Temperature

Low average temperatures, approximately between 0°C and 10°C.

Temperature Range

Large thermal amplitude. Cold winters and warm/hot summers.

Rainfall

Low to moderate precipitation, generally less than 600 mm per year. Irregular pattern: Dry winters and rainier summers.

Vegetation

Coniferous forests (Taiga) and temperate grasslands (meadows/prairies).

Polar Climate

Location

Regions within the Polar Circles (Arctic and Antarctic).

Temperature

Low temperatures, average typically below 0°C year-round (or only slightly above in the warmest month). Cold climate.

Temperature Range

High annual thermal amplitude, often greater than 25°C.

Rainfall

Low precipitation, occurring primarily as snow.

Vegetation

Tundra (mosses, lichens); ground often permanently frozen (permafrost).

High Mountain Climate

Location

High altitude zones in mountain ranges worldwide.

Temperature

Temperature decreases with altitude (approximately 6°C per 1000 meters). Generally a cold climate at higher elevations.

Temperature Range

Variable thermal amplitude, often more than 10°C, depending on altitude and specific location.

Rainfall

High precipitation, often more than 1000 mm per year. Precipitation generally increases with altitude up to a certain point and frequently falls as snow.

Vegetation

Vegetation is zoned according to altitude and adapted to cold temperatures and terrain (orography).
