US Temperature & Precipitation Patterns: Quick Study Notes
The climate of the United States varies drastically due to its vast size, latitudinal range, and topography. Understanding the interaction between ocean currents, mountains, and air masses is key to mastering US geography.
Key Takeaways
- The 100th Meridian historically divides the humid East from the arid West.
- The Gulf of Mexico is the main moisture source for the Eastern US.
- Orographic lift causes heavy rain on the windward side of mountain ranges.
- Lake Effect Snow occurs when cold air moves over warmer Great Lakes waters.
- Mediterranean climates (CA) feature wet winters and dry summers.
Frequently Asked Questions
Why is the West Coast milder than the Midwest?
The Pacific Ocean moderates temperatures, preventing the extreme heat and cold found in the continental interior (Midwest).
What is the Rain Shadow effect?
It occurs when a mountain range blocks prevailing winds, forcing moisture to drop on one side, leaving the other side dry (e.g., Nevada).
Why does the Southeast get so much rain?
Warm, moist air from the Gulf of Mexico is pumped northward, fueling frequent storms and humidity.
How does latitude affect US temperatures?
Generally, areas closer to the equator (South) receive more direct sunlight and are warmer than areas closer to the poles (North).
What causes the Southwest Monsoon?
A seasonal shift in wind patterns in late summer brings moisture from the Gulf of California and Gulf of Mexico into the arid Southwest.
