Air Pressure
In which direction does air travel around a High Pressure System?
Clockwise and Upwards
Names of the Global Winds.
Polar Easterlies, Prevailing Westerlies, Trade Winds
What Air Mass is dry and cool?
Continental Polar (cP)
What are the characteristics of a Cold Front?
Steep slope of air, low pressure, fast and violent storms, starts warm and ends cold
What is the Troposphere?
Bottom layer of the atmosphere, where people live and planes fly.
In which direction does air travel Around a Low Pressure System?
Counter-clockwise and Downwards
Where do the Trade Winds blow from?
The East
What Air Mass is dry and warm?
Continental Tropical (cT)
What are the characteristics of a Warm Front?
Gradual slope increase, high pressure, long and weak storms, starts cold and ends warm.
Troposphere Characteristics
Dense Atmosphere
What weather does a High Pressure System produce?
Clear Skies, Sunny, and Dry
At what Latitude is the High Pressure band found?
30* North and South near both poles.
What Air Mass is wet and cool?
Maritime Polar (mP)
What are the characteristics of a Stationary Front?
Very steep air slope, low pressure, very long and spitting storms, warm on one side and cold on the other.
What does the Ozone Layer do?
Shield the Earth from the Sun's radiation.
What weather does a Low Pressure System produce?
Cloudy and Windy, possibly Rainy
At what Latitude is the Low Pressure band found?
50*-60* north and south
What Air Mass is wet and warm?
Maritime Tropical (mT)
What are the characteristics of an Occluded Front?
No steep slope, low pressure, heavy but short storms and strong winds, starts warm and ends cold.
Where is the Ozone Layer?
Inside the stratosphere, between 15-40 km above the Earth.
How does wind flow?
From a High Pressure System to Low Pressure System
Where do the winds blow to and from?
Polar Easterlies: 60-90 Degrees Latitude
Prevailing Westerlies: 30-60 Degrees Latitude
Trade Winds: 0-30 Degrees Latitude
What Air Mass is dry and VERY cold?
Continental Arctic (cA)
