The hail stone reaches the ground as ice since it is not in the warm air below the thunderstorm long enough to melt before reaching the ground. Terms for using data resources. CD-ROM available. Precipitation starts as snow in the cold layer at the top, then melts to rain as it falls through the warm layer, then refreezes into sleet or freezing rain as it falls through the cold layer near the surface. For sleet to occur, the warm air layer is rather thin.
A thicker wedge of cold air beneath the warm air refreezes the partially melted snow into ice pellets. For freezing rain to occur, the warm air layer is thicker.
The snow melts into rain then refreezes just as it hits the cold ground. Since the rain is not freezing until it reaches the surface, it still falls like regular rain and therefore looks and feels the same until it freezes on the ground. Sleet is made up of ice pellets that bounce off objects.
Even though this may sound more hazardous than freezing rain, that's not the case.

Most people think of a blizzard as a bad snowstorm, but a winter storm must meet certain criteria to be classified as a blizzard. According to the National Weather Service, a blizzard is a weather event that includes low temperatures, wind speeds greater than 56 kilometers 35 miles per hour, and a large amount of falling or blowing snow that lowers visibility to 0. These whiteout conditions can cause car accidents and people on foot to become lost.
Additionally, the colder temperatures that often follow a blizzard can put people at risk of frostbite or hypothermia. Explore more about blizzards with this collection of resources.
Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere before precipitating. We pay for videos too. Click here to upload yours.
