In most north latitudes, the regions are covered with snow almost all the year round.
Cold and freezing winds are common in northern latitudes. This means that the climate of the regions in northern latitudes is extremely chilly and mostly frost is found.
A few frost-free days may be seen when the 'sun shines bright' and is visible.
