Often, in the winter months, cool or cold dry air settles over the land in the vicinity of the
high-pressure cell or anticyclone that moves across the United States with a cold front on its leading edge. After reaching the Atlantic Ocean, the moist environment results in a change of air quality and the dissipation of the high-pressure cell or anticyclone as the cold air warms and becomes humid. In Europe, a portion of the North American/Canadian High commonly over Greenland
, called the Greenland High, affects northern European weather and may merge with the Scandinavian High.
