US Map of Deserts: Climate and Geography
Understanding the US desert map also requires understanding the climate and geography that shape these arid regions.
- Rain Shadow Effect: Many US deserts are formed by the rain shadow effect. Mountain ranges block moisture-laden air, causing precipitation on the windward side and leaving the leeward side dry.
- High Pressure Systems: Persistent high-pressure systems can also contribute to desert formation by suppressing rainfall.
- Elevation: The elevation of a desert influences its temperature. Higher elevation deserts, like the Great Basin, experience colder temperatures than lower elevation deserts like the Mojave.
