Air masses form when air remains over a region long enough to acquire the temperature and moisture characteristics of that area. This process typically occurs in large, stable regions where the air can stagnate, allowing it to reach thermal equilibrium with the underlying surface. As a result, air masses can be categorized based on their origin, such as maritime or continental, and their temperature profiles, such as tropical or polar.
Maritime Masses form over water.
Continental Masses form over Land.
Atomic fusion occurs when masses combine to form elements with larger mass.

The US is not a great place for air masses to form because it is surrounded by oceans on three sides, which limits the development of continental air masses. In addition, the complex topography and variability of the climate in the US make it difficult for stable air masses to form and persist over large areas.
A region where air masses can form must be fairly flat and uniform in terms of temperature and moisture content. This allows for the development and maintenance of distinct air masses with consistent characteristics.
Air masses form when air remains stationary over a particular region for an extended period of time. This allows the air to acquire the temperature and moisture characteristics of that region, creating a distinct air mass with specific properties. Movement of the air mass can then transport these characteristics to other regions.
Maritime Masses form over water.
A cold air mass originates over water or land that is colder than the air temperature at the time. Cold air masses usually originate in the northwest and travel eastward. A warm air mass is formed from warm water or ground temperature that is warmer than the air at the time. Warm air masses usually originate in the southwest and travel east or northeast.
Maritime Masses form over water.
Continental Masses form over Land.
The cool air sinks, while the warm air rises. If it does so with enough force and torque, a tornado or hurricane will form.
The United States is not a good place for air masses to form because it is a relatively small country with diverse landscapes and climates, making it difficult for stagnant air masses to develop over a long period of time. Additionally, the presence of the Rocky Mountains and the Gulf of Mexico can disrupt the formation and movement of air masses in the region.
Continental air masses form in the United States
Atomic fusion occurs when masses combine to form elements with larger mass.
Air masses that form over Canada are usually continental in nature, meaning they are dry and cold, especially in the winter months when they originate from the Arctic region. These air masses tend to bring colder temperatures and clear skies to the regions they move into.
Air masses are formed primarily over large, uniform areas of land or water. Continental polar air masses form over cold, dry land regions, while maritime tropical air masses form over warm, moist ocean regions. They can also be influenced by factors like temperature, humidity, and wind patterns in the region where they originate.
