Air Masses and Fronts
Changes in weather are caused by the movement of bodies of air called
What is Air Masses
Calm weather is approaching with this air mass
What is high pressure
Horizontal, stream like movements of water that are found near the surface of the ocean
What is Surface Currents
The name of movements of ocean water deep down below the surface
What is Deep currents
Scientists classify air masses using two factors
What is water content and temperature
Blue triangles on a weather map usually indicate
What is a cold Front
There are there factors that affect surface currents
What is global winds, the Coriolis effect, and continental deflections
The density if ocean water is effected by this thing
What is Salinity
Air masses that form over deserts and bring hot dry weather
What are continental air masses
Red cemi-circles on a weather map usually indicate
What is a warm Front
The Coriolis effect causes these two things to move along curved paths
What is wind and water
Deep currents mostly form near this part of the Earth
What is poles
The place where two or more air masses meet
What is a Front
Areas on a map with an "L" have what type of weather
What is stormy weather
This thing blows across the Earth's surface and pushes water to make surface currents
What is wind
When ocean water is cold and salty this makes the water more
What is denser
This will happen when a warm Front meets a cold Front
What is rise
Areas with calm cloudy weather are likely experiencing
What is a stationary front
This happens when surface currents come face to face with cotinents
What is deflect
Near where the poles are, heat moves from ocean water to
What is colder air
