The altitude in metres at which the temperature dips below the freezing point is illustrated on the map. This altitude has a large influence on the state of precipitation. At altitudes above this level, precipitation generally occurs in solid states (snowflakes, ice crystals). At lower altitudes, on the contrary, precipitation occurs in a liquid state. This does not, however, always have to be the case. In some instances, snowfall may occur at lower altitudes as well. This is due to the fact that snow does not melt immediately at temperatures above the freezing point, but melts gradually. Therefore, primarily in low humidity, it can snow up to 400 m below this altitude. During temperature inversions, freezing precipitation may fall at this altitude.
