nival climate

…a type of nival climate in which the average temperature of the warmest month is below 0°C.

In contrast to a semi-nival climate, in which the snow does not fall entirely as snow but may be mixed with rain, a completely nival climate in which there is only snow and no rain is called a permafrost climate.
