An arctic air mass is a mass of cold air that originates from the Arctic region and is characterized by very cold temperatures and high humidity. These air masses form over the polar regions which are characterized by snow and ice cover throughout the year and they can often spread southward to affect mid-latitude regions. Arctic air masses are usually very stable and move slowly meaning that they can last for long periods of time. They can also be quite dry and they often bring cold weather and snow to the regions they affect.
Arctic air masses are typically classified according to their temperature and moisture content. The following are the three main types of arctic air masses:
Arctic air masses can cause a variety of weather phenomena including snowstorms blizzards and extreme cold waves. They can also cause a drop in temperatures in affected areas resulting in frost and even freezing temperatures. As such it is important to be aware of arctic air masses and their potential impacts on weather and climate.
arctic air mass is simply a mass of highly or very cold air in the arctic regions which invades lower latitudes at irregular intervals.
the cold air mass took the place of the large air mass

A warm front forms.
No single air mass "causes" tornadoes. This is Tornadoes form within thunderstorms. Thunderstorms form best when there is plentiful warm, moist air. So, a arm, moist air mass is usually present. Significant tornado activity, however, usually results from the thunderstorms that form near the boundaries between air masses. Usually where a warm, moist air mass meets a cooler or drier air mass.
its a stationary front
The Arctic air is more dense, and therefore does not rise as easily.
It refers to the air above the Arctic continent.

A cold air mass is a mass of air that has colder characteristics than the surrounding air.
Air mass is a small volume of air defined by its temperature and water vapor content.Colder air masses are termed polar or arctic.

Arctic air masses come from the very far north usually way north of the arctic circle and can originate as far north as the north pole causing the coldest weather this is usually the coldest air mass with very little moisture arctic air masses exist anywhere from 75-90 degrease north this is why they are colder than a polar air mass . Polar air masses usually come from lower latitudes from around 65-73degress north this is there source of origin they cause cold winter temperatures with a lot of snow they are still cold air masses just not as bitingly cold as that of its further north component. Don't be fooled by the names even though it says polar its still coming from a further south origin compared to the arctic airmass. If i were the person who named these are masses i would say polar is colder than arctic but its just the way they label it.
There are six letters that are used to designate the source region of air mass. These include T (Tropical), E (Equatorial), S (Superior air), M (Monsoon), P (Polar), and A (Antarctic or Arctic).
The duration of Arctic Air is 2700.0 seconds.
