During the coldest months, the temperature may drop to -50 degrees in periglacial regions. The ground is totally frozen and covered with a thin layer of snow. In fact, the anticyclonic conditions above the tundra in winter make the air too dry for much precipitation to develop. Icy winds sweep the landscape, sometimes uncovering rocks. | |
