Best Answer

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:

  • Polar Maritime (Pm): These air masses form over the Arctic Ocean and are usually moist with temperatures ranging from -5 to +5 degrees Celsius.
  • Polar Continental (Pc): These air masses form over the continent of North America and are usually dry with temperatures ranging from -20 to -30 degrees Celsius.
  • Polar High (Ph): These air masses form over the high Arctic and are usually dry with temperatures ranging from -30 to -50 degrees Celsius.

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.
