A very large volume of air that has a certain temperature and moisture content.
What is... an air mass
This is the abbreviation for the air mass Maritime Tropical.
Horizontal, stream-like movements of water that are found at or near the surface of the ocean.
What is... surface currents
What is... deep currents
These two variable determine the classification of an air mass.
What is... water content and air temperature
This is the word that describes a dry air mass.
These three factors affect surface currents.
What is... global winds, the Coriolis effect, and continental deflections
These two factors determine the deep currents.
What is... density and salinity
These are the four different fronts that can occur when two air masses meet.
What is... warm, cold, occluded, and stationary
Cold air masses bring this kind of weather during the summer.
What is... cool and dry with fog
What is... east to west
This is the deepest and densest water in the ocean.
What is... the Antarctic Bottom Water
These are the four different air masses that are found in the United States.
What is... continental polar, maritime polar, maritime tropical, and continental polar
What is... northern Canada
Surface currents do this when they meet continents.
What is... deflect
Deep currents form when these two things happen.
This front is formed when a warm air mass is caught between two cold air masses.
Warm fronts bring this kind of weather.
What is... light rain, followed by clear and warm weather
This is the deflection of moving objects from a straight path because of the Earth's rotation.
What is... the Coriolis effect
These are the three main ways that ocean water density can increase.
What is... decreasing temperature, increasing salinity through freezing, and increasing salinity through evaporation
