Which air mass often originates as a different air mass in Siberia and is subsequently alrered?

Answer 1

The air mass that often originates in Siberia and is subsequently altered is the Continental Polar (cP) air mass. It starts as cold, dry air over the Siberian land and can be modified as it moves over warmer surfaces or interacts with other air masses, leading to changes in temperature and moisture content. This modification can result in significant weather phenomena as it moves into different regions.
