climatic region

Geographical area which experiences certain weather conditions. No two localities on Earth may be said to have exactly the same climate, but widely separated areas of the world can possess similar climates. These climatic regions have some comparable physical and environmental features as well as having similar weather patterns. Climatic regions are differentiated by weather conditions (including temperature, humidity, precipitation type and amount, wind speed and direction, atmospheric pressure, sunshine, cloud types, and cloud coverage), and by weather phenomena (such as thunderstorms, fog, and frost) that have prevailed there over a long period of time, usually 30 years.
