What’s the difference between snow, freezing rain, sleet and hail?

Rain, which is liquid water droplets known as raindrops, is one of the few precipitation types that can occur during any season. As long as air temperatures are above freezing (32 F), rain can fall. For snow to fall outside your window, air temperatures above the surface must be.

The term graupel is the German language word for sleet. Graupel is distinct from hail , small hail and ice pellets : the World Meteorological Organization defines small hail as snow pellets encapsulated by ice, a precipitation halfway between snow pellets and hail. Small hail is common in thunderstorms, while graupel typically falls in winter storms. Under some atmospheric conditions, snow crystals may encounter supercooled water droplets. Contact between a snow crystal and the supercooled droplets results in freezing of the liquid droplets onto the surface of the crystal. This process of crystal growth is known as accretion.

As we make it through the winter , meteorologists in many parts of the country are predicting all sorts of cold - weather precipitation : snow , sleet , freezing rain. But what's the difference? All precipitation falls through the atmosphere on its way to the Earth's surface. Imagine a drop or flake falling through a long tube that contains the air between the clouds and the Earth. The air inside the imaginary tube is the atmosphere. Differences in temperatures in different parts of the atmosphere account for the differences we see between snow , sleet , and freezing rain.

Winter Storm Stella came with plenty of snow, as advertised, but it also unleashed a surprising amount of sleet and freezing rain. How do these different types of precipitation form? While all forms of precipitation start as snow high up in the clouds, there are four primary types that eventually reach the ground: snow, sleet, freezing rain and plain ol' rain. 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.

AS snow and ice descends over the UK, not everyone is clued up on the different types of weather phenomenons that strike when the temperature falls. All forms of precipitation atmospheric water which falls to the ground starts as snow high up in the clouds. But the precipitation only stays as snow when the atmosphere is cold all the way from the clouds to the ground. Snow is formed when temperatures are low and there is moisture in the atmosphere in the form of tiny ice crystals. Hail occurs during severe weather such as thunderstorms when dust or particles in the air collide with cold water.



Rain, Snow, Sleet, and Other Types of Precipitation

Why do we sometimes get rain and sometimes get snow? These are different types of precipitation, but what does 'precipitation' mean?, Precipitation: What makes clouds, rain, snow, hail and sleet When warm, wet air rises, it cools, and water vapor condenses out to form clouds.

Winter Storm Stella has come with plenty of snow, but it has also unleashed a surprising amount of sleet and freezing rain.

  1. Whether or not precipitation remains snow or transitions to rain, freezing rain, sleet, hail or graupel by the time it reaches the ground hinges on.
