In the United States air masses move across the country by air currents. These air currents are pushed by either hot or cold air masses.
Continental air masses form in the United States
Air masses move across the US primarily due to the prevailing wind patterns, which are influenced by the rotation of the Earth, temperature gradients, and pressure systems. For example, westerly winds move air masses from west to east across the country. Additionally, the jet stream can also play a role in steering air masses.
The North America air masses is what causes cold waves. This is in the Central Eastern United States.
There are 4 types of air masses in North America: maritime tropical, maritime polar, continental tropical, and continental polar. In the continental United States, air masses are moved by the prevailing westerlies and the jet streams.
Air masses move across the US primarily due to the jet stream, which is a fast-flowing, narrow band of air at high altitudes that often guides the movement of weather systems. Temperature and pressure differences between air masses also play a role in their movement, causing them to shift and interact with each other as they move across the country.
The primary source regions for air masses that affect weather in the United States are the Arctic region to the north, the Pacific Ocean to the west, the Gulf of Mexico to the south, and continental regions to the east. These air masses bring different temperature, humidity, and stability characteristics, influencing weather patterns across the country.

6 Major masses affected the united states
The Arctic air masses that come from the Arctic region cause cold waves over the central and eastern United States. These air masses bring bitterly cold temperatures and can result in severe winter weather events such as snowstorms and blizzards.
air masses move because the gravity and air paressure are making them move..
