1. Latitude: This is the primary factor determining temperature. The further away from the equator (higher latitude), the less direct sunlight a location receives, leading to colder temperatures. This is why the northern US has a colder climate than the southern US.
2. Elevation: Higher elevations experience lower temperatures due to thinner air, which is less able to retain heat. This is why mountainous regions like the Rockies have a colder climate than lower-lying areas.
3. Proximity to Large Bodies of Water: Water moderates temperatures, leading to warmer winters and cooler summers in coastal areas compared to inland regions. This is why the Pacific Northwest has a milder climate than the Great Plains.
4. Prevailing Winds: Winds carry moisture and temperature patterns. For example, the prevailing westerly winds bring moisture from the Pacific Ocean to the West Coast, leading to a wetter climate.
These four factors work together to create the diverse range of climates found across the US, from the humid subtropical climate of Florida to the arid desert climate of Arizona.
