Study Notes
Hot Desert Biome Climate
- Hot deserts are arid, with high temperatures and little precipitation.
- Summer days exceed 40°C, dropping to 15°C at night.
- Winter days average 25°C, falling to near 0°C at night.
- Direct sunlight concentrates heat on a small area, increasing ground temperatures.
- Lack of vegetation means the ground absorbs and radiates heat, increasing temperatures.
- Rapid temperature drops after sunset due to clear skies.
- Rainfall is infrequent, typically between 0 and 250 mm per year, in short, intense bursts.
- Rainfall is often unevenly distributed.
- Rain shadow effect occurs near western edges of continents due to mountains, causing drier conditions inland.
- Moisture-laden winds carry precipitation to coastal mountain ranges, causing rain on the windward side.
- This leads to drier conditions inland, contributing to the desert environment.
- High pressure belts between 15° and 30° latitude cause low rainfall due to dry, cold air.
