Desert climate

  • Desert climate
  • Savannah climate
  • Tundra
  • Eisklima
  • Humid climate
  • Semi-arid climate
  • Arid climate

In an arid climate (from the Latin aridus: dry, arid ) exceeds the potential evaporation to precipitation of a region. This has a very low humidity result. It is the opposite of the humid climate. The extremely arid areas are designated as wilderness.

A distinction is made:

  • Vollarides Climate: precipitation < evaporation valid for ten to twelve months a year
  • Semi-arid climate: precipitation < evaporation is valid for six to nine months a year.

A typical feature of a vollarides area is its Abflusslosigkeit. Rivers evaporate completely in their course or end in endorheic lakes or salt pans. Examples represent the Lake Urmia or the Aral Sea dar. In Vollaridität are constantly dry climate conditions with less than 80 mm of rainfall a year ago. While most dry areas are in the subtropical desert belt, because the trade winds reach only up to the so-called horse latitudes, but there are arid climates as well as in other regions, for example, in many high mountains.

After Lauer and Frankenberg ( ecophysiological climate classification )

The ecophysiological climate classification defines the Humidität or aridity on the duration of hydric vegetation period in months. Lauer and Frankenberg define the following classes:

  • Perarid: 0 months
  • Arid 1 to 2 months
  • Subarid: 3 to 4 months
