Explanation:
The majority of the precipitation, which reaches the ground, in reality, develops in the form of snow high in the atmosphere. The formation of snowflakes takes place at the temperature above the freezing level, that is, less than 32 degrees F, and starts to fall towards the Earth in the form of snow.
However, if the temperature of the ground is more than 32 degrees F, the level of freezing must be situated at some level above the ground. The snow that falls goes through the level of freezing into the warmer air, and here it gets melt and transforms into rain before contacting the ground.
