A climate that is characterized as tundra

Tundras are among Earth's coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant.

A climate which is characterized as tundra receives "less than ten inches" of "precipitation".

Explanation:

The Tundra climate is scientifically identified to be the one which is particularly experienced between the temperate and the polar climatic zones. The precipitation in the region (except in Alpine tundra) is less than ten inches per year. The average annual precipitation is around 7 inches. The human inhabitants of the Tundra are called Eskimos. Animals like Reindeers and Arctic Foxes are found in Tundra.
