Explanation

The cold zones are the arctic and subarctic. In the arctic zone cold arctic air dominates all year: summer is +1…+3 °C, winter about –40 °C, annual precipitation is 50–100 mm and falls as snow, and much of the land is covered with ice. The subarctic zone stretches from northern Scandinavia to the Bering Sea; summer is +4…+14 °C, precipitation 200–400 mm, with cold winds and many cloudy days. The temperate zone takes up the largest part of Eurasia, from the Atlantic in the west to the Pacific in the east, and has four climate types: maritime, temperate-continental, continental and monsoon. In the western maritime climate winters are mild (January about 0 °C), summers cool (+15…+20 °C), and rainfall over 1 000 mm falls all year. Inland continentality grows, rainfall falls and winters become colder. On the Pacific coast there is a monsoon climate: most rain (about 90 %) falls in summer, while winter is dry and cold. The main difference between the cold and temperate zones is summer temperature and the rainfall pattern.

Worked examples
In the arctic zone it is +3 °C in summer and –40 °C in winter: a difference of 3 + 40 = 43 °C.
In a monsoon climate rain falls in summer; in a maritime climate it is spread through the year.
Class activity

“Climate cards”: make four cards (maritime, temperate-continental, continental, monsoon). On each write summer temperature, winter temperature and rainfall.
