fronts
the weather front model with a line of just triangles
what is the cold front?
the pressure system that brings sunshine and good weather
what is a high-pressure system?
a large body of air measured by temperature and humidity
what is an air mass?
What causes wind?
Differences in air pressure
What are the main wind belts near the equator called?
Trade winds
the four types of weather fronts
what are cold fronts, warm fronts, stationary fronts, and occluded fronts?
the type of front in a dry climate
what is a warm front?
the two air masses that are over the ocean
what are maritime polar (mP) and maritime tropical (mT) air masses?
What happens to air as it warms?
It rises
What are winds between 30° and 60° latitude called?
Prevailing westerlies
the kind of front that forms when a cold mass and a warm mass meet but neither have enough force to move
what is a stationary front?
What way do storm tracks typically move?
What is North east
the things maritime polar air masses are associated with
what is cool, moist, and unstable air?
What causes storm systems to spin?
Coriolis effect
Why does air rise at the equator and sink near 30° latitude?
Uneven heating causes pressure differences and circulation
the way an occluded front is formed
what is an air mass getting caught between two cold air masses?
the large body of circulating air with low pressure at its center and higher pressure outside the system
what is a low-pressure system?
the two things air masses are classified by
what is temperature and moisture?
What large-scale pattern helps guide storms?
Global wind patterns
What large circulation cells control global wind belts?
Hadley, Ferrel, and Polar cells
Which front causes warm air to rise the fastest?
cold front
What weather pattern is caused by a low-pressure system?
Cloudy, stormy, and rainy weather.
things air masses are commonly moved by in the u.s.
what are prevailing westerlies and jet streams?
a diagram that displays data from many different weather measurements for a specific location
what is a station model?
How does the Coriolis effect influence global wind patterns?
It deflects moving air, causing winds to curve instead of moving in straight lines.
