Study Notes
Air Masses
- Air masses that form over land are called continental air masses.
- Maritime air masses are characterized by high humidity and cool temperatures.
Formation of Air Masses
- Tropical air masses primarily form near the equator.
- Maritime tropical air masses primarily form in North America over the Gulf of Mexico and the Caribbean Sea.
Characteristics of Air Masses
- The temperature of an air mass gives an idea of its overall temperature.
Predicting Weather with Air Masses
- Meteorologists typically use air masses to predict weather by understanding the properties of different air masses and how they interact with each other.
Maritime Arctic Air Masses
- Maritime arctic air masses are cold and moist, and form over the Arctic Ocean.
Comparison of Air Masses
- Continental polar air masses feature higher humidity than maritime arctic air masses.
Formation of Continental Polar Air Masses
- In North America, the continental polar air mass primarily forms over the Arctic regions of Canada and Alaska.
Weather Conditions and Air Masses
- When air masses with different temperatures and humidity levels run into each other, it causes different weather conditions.
Cloud Formation
- Cumulus clouds can turn into towering cumulonimbus clouds during stormy weather.
- Orographic lifting occurs when a warm air mass rises and condenses to form cumulus clouds.
Convectional Lifting
- Convectional lifting occurs more frequently in areas with warm temperatures and high humidity, such as near the equator.
Air Masses and Mountains
- When air masses encounter mountains or landforms, they are forced to rise, cool, and condense, resulting in precipitation.
- One side of a mountain receives more precipitation than the other side due to orographic lifting, as the air is forced to rise and cool, resulting in precipitation on the windward side.
