Which letter code indicates mid-latitude desert climate in Köppen climate classification?

The correct answer is BWk.

Key Points

• In the Köppen climate classification, BWk represents the mid-latitude desert climate.
• This climate type is characterized by low annual precipitation, typically less than 250 mm (10 inches).
• BWk climates usually have hot summers and cold winters, distinguishing them from the hot desert climates (BWh).
• Examples of regions with BWk climate include parts of the Gobi Desert in Mongolia and China.
• This classification helps in understanding the geographical distribution of arid and semi-arid regions.

Additional Information

• Köppen Climate Classification
  • Developed by Vladimir Köppen, this classification system categorizes the world's climates based on temperature and precipitation.
  • The main categories are Tropical (A), Dry (B), Temperate (C), Continental (D), and Polar (E).
  • It is widely used in climatology, geography, and environmental science to study climate patterns.
• Desert Climate (BWh)
  • Hot desert climates (BWh) have extremely high temperatures during the day and cool temperatures at night.
  • These regions receive very little rainfall, often less than 250 mm annually.
  • Examples include the Sahara Desert in Africa and the Arabian Desert in the Middle East.
• Steppe Climate (BSk)
  • Steppe climates (BSk) are semi-arid regions that receive slightly more precipitation than deserts.
  • These areas have hot summers and cool to cold winters.
  • Examples include the Great Plains in the United States and the Eurasian Steppe.
• Climate Change Impact
  • Climate change is altering precipitation patterns, potentially expanding desert and semi-arid areas.
  • Understanding climate classifications helps in predicting and mitigating the impacts of climate change.
