Which wind pattern has the most influence over the movement of frontal weather systems over the North American continent?

🔍 Key Concepts

• Global wind belts and how they are arranged by latitude • Typical track of mid-latitude low pressure systems across North America • Difference between trade winds, westerlies, and polar easterlies

💭 Think About

• At the latitude of most of the U.S. and southern Canada, which global wind belt is dominant? • Frontal systems that bring rain and snow across the continent are usually associated with what type of pressure system? • Do those systems generally move from west to east, or east to west, across North America?

✅ Before You Answer

• Identify the approximate latitude range of the North American continent where most frontal systems occur (think mid-latitudes). • Match each answer choice to its typical latitude band on a global wind map. • Eliminate any wind patterns that mainly affect the tropics or far polar regions, rather than the mid-latitudes.
