Continentality


Continentality is a measure of the difference between continental and marine climates characterized by the increased range of temperatures that occurs over land compared with water. This difference is a consequence of the much lower effective heat capacities of land surfaces as well as of their generally reduced evaporation rates.   Source: Encyclopædia Britannica, Inc
