The three descriptors for an air masses' temperature.
Tropical, Polar, Arctic
The width of weather created by a cold front.
About 50 nautical miles.
Characteristics marking the passage of a warm front.
A rise of temperature and the sky becoming relatively clear.
An occlusion where the advancing air is colder than the air mass it is overtaking.
A Cold Occlusion.
The three factors that decide weather in an air mass.
What does the cooling process, stability of, and the moisture content have to do with air masses?
How a cold air mass interacts with a warm air mass in a cold front.
Undercuts the warm air forcing it upwards.
Why a warm front has more extensive weather than a cold front.
Slow speed and shallow frontal slope.
The acronym for trough of warm air aloft.
A trowal.
The characteristics of a cold air mass.
What does instability, turbulence, good visibility, cumuliform clouds, precipitation (showers, hail, and thunderstorms) relate to?
A sharp fall in temperature, a rise in pressure, and rapid clearing of weather usually indicates this.
The passage of a cold front.
How far the weather from a warm front can extend.
500 nautical miles or more.
What warm and cold occlusions share characteristics with.
A warm front.
The characteristics of a warm air mass.
What does stability, smooth air, poor visibility, stratiform clouds and fog, precipitation in the form of drizzle relate to?
A continuous line of thunderstorms forming ahead of fast moving cold front.
A squall line.
What CCANS stands for.
Cirrus, Cirrostratus, Altostratus, Nimbostratus, Stratus.
