300
What type of weather occurs at a warm front?
Scattered clouds, light rain that may last several days.
300
What does "humidity" refer to?
The amount of moisture in the air.
300
What does "dew point" mean?
The temperature at which water vapor in the air will condense into droplets.
400
What two characteristics are air masses categorized by?
Temperature and humidity
400
What front occurs when one warm air mass is wedged between two colder air masses.
Occluded front
400
What type of air mass would develop off the coast of Chile?
Maritime Topical (mT)
400
What is the difference between weather and climate?
Weather is the short term conditions of the atmosphere. Climate is the long term condition of the atmosphere.
400

Exosphere
500
Name the four types of air masses and what type of characteristics they have.
Continental Polar (cP) - dry, cold
Continental Tropical (cT) - dry, hot
Maritime Polar (cP) - moist, cold
Maritime Tropical (mT) - moist, hot
500
What weather occurs as a result of a cold front?
Thunderstorms, heavy rain, possible snow
500
What is a weather front? How is it different than an air mass?
A weather mass is the point where two air masses meet. Weather occurs at a front, whereas the body of an air mass would not experience that same weather.
500
Explain why low pressure means lousy weather.
Low pressure > Air is less dense > Air rises > Water vapor rises > Water vapor condenses in the air > Forms clouds
