High arctic climate

From Glossary of Meteorology

high arctic climate

In Nordenskjöld's climatic classification (1928), the climate of those parts of the world where the average temperature of the warmest month is below 0°C.

It is equivalent, therefore, to the perpetual frost climate of W. Köppen (1918), and to C. W. Thornthwaite's frost climate (1931).
See polar climate.
