Brief Explanations:

Siberia is a vast region located in Northern Asia, characterized by its landlocked nature far from the moderating influence of oceans. In meteorology and geography, air masses are classified by their moisture content (maritime for moist, continental for dry) and their temperature (arctic/polar for cold, tropical for warm). Because Siberia is a large landmass at high latitudes, it serves as a source region for air masses that are extremely cold and dry. Therefore, it is classified as a continental arctic (cA) or continental polar (cP) source region depending on the specific season and latitude, but "Continental arctic" best describes the extreme cold and dry conditions associated with the Siberian High.

Answer:

Continental arctic
