Snow pellets, also known as graupel, form when supercooled water droplets freeze on a falling snowflake or ice crystal. As more droplets collect and freeze, they form a small, soft ball of ice. … Unlike hail, snow pellets freeze into fragile, oblong shapes and usually break apart when they hit the ground.
If the temperature is above freezing below the cloud bottom to the ground, the frozen particles melt into liquid droplets that reach the surface and this is called rain. … They almost look like tiny styrofoam pellets.
Under these conditions, when the falling snow reaches the layer of warm air, it melts. Then it hits the layer of cold air just above Earth’s surface and refreezes. This all happens very fast, and the result is tiny ice pellets called sleet. Sleet, Freezing Rain, Hail …
Hail can occur at any season, and it occurs during strong thunderstorms. Every storm has an updraft that gathers super-cooled water droplets in an updraft. … Hail is more common than snow, because you don’t need the air to be at freezing temperatures, like snow.
Freezing rain develops as falling snow encounters a layer of warm air deep enough for the snow to completely melt and become rain. … When the supercooled drops strike the frozen ground (power lines, or tree branches), they instantly freeze, forming a thin film of ice, hence freezing rain.
Cold fronts are responsible for most of the rainfall received in the winter rainfall region of the Western Cape. … The year-round rainfall region includes most of the south coast and it receives rain when an onshore wind pushes moist air inland and up against the mountains in summer and from cold fronts in winter.
The different types of precipitation are:
Sleet / Ice Pellets (PE, PL, IP, SLT):
Sleet (Ice Pellets) are frozen raindrops that strike the earth’s surface. In a sleet situation the precipitation aloft when it is first generated will be snow. The snow falls through a layer that is a little above freezing and the snow partially melts.
Graupel is formed when snowflakes encounter super-cooled water droplets in subfreezing clouds. In a process called rime accretion, the water droplets flash freeze around individual snowflakes to create granular balls of white. That weekend in mid-February, atmospheric conditions were just right for generating graupel.
hail (interj.) salutation in greeting, c. 1200, from Old Norse heill “health, prosperity, good luck,” or a similar Scandinavian source, and in part from Old English shortening of wæs hæil “be healthy” (see health; and compare wassail).
Sleet falls as clear ice pellets. … Sleet is a winter weather occurrence and is usually appear as clear, hard pellets.. Sleet starts out as snowflakes high in the clouds, then falls through a warm layer of air, where it melts and turns into partially melted snowflakes and raindrops.
Generally, freezing rain or sleet pellets are not large enough to cause any scratches or dents. … The problem comes when an accumulation of rain, sleet or snow retain dirt and grime that CAN scratch your clear coat (see your car’s different layers here).
“Freezing rain is by far the most dangerous because it forms a solid sheet of ice, as opposed to sleet that just has small ice pellets that quickly bounce off of the surface,” AccuWeather Senior Meteorologist Brett Anderson said.
Rain and snow mixed (also known as sleet) is precipitation composed of rain and partially melted snow. This precipitation can occur where the temperature in the lower part of the atmosphere is slightly above the freezing point (0 °C or 32 °F). Its METAR code is RASN.
Hominy snow: a term used primarily in the South Midland region, refers to an icy, granular snow that looks like hominy. … Perennial snow: Snow that remains on the ground for more than a year.
Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts. … If the water freezes instantaneously when colliding with the hailstone, cloudy ice will form as air bubbles will be trapped in the newly formed ice.

Hail, like rain, or other forms of natural precipitation, is just water, only that it is frozen during its path up and down in between gravity and up-draft before landing. So hail, yes we can eat hail just like we can eat ice (pun intended)! Most of our Global drinking water is indeed collected from precipitation.
In fact, snow can fall at temperatures as high as 50 degrees. Most residents of the northern United States have probably seen 40-degree snowfalls before, but snow at temperatures greater than 45 degrees is hard to come by. … When moisture overlaps with below-freezing temperatures at cloud level, snowflakes can form.
Weather stations with highest snowfall in the United States by state, 1985-2015
|State||Place||Average annual snowfall|
|1. Washington||Paradise, Mt. Rainier||645.5 inches (1,640 cm)|
|2. Oregon||Timberline Lodge Ski Area||551 inches (1,400 cm)|
|3. Utah||Alta||456.9 inches (1,161 cm)|
|4. California||Soda Springs||411.6 inches (1045 cm)|
Snowflakes are compressed into round grains trapping and squeezing air. Snow grains fuse and deform. Air bubbles close off between snow grains – firn is formed. The transformation of snow to firn and eventually solid ice is caused by the increasing weight of the ice.
The National Weather Service defines a blizzard as a storm with large amounts of snow or blowing snow, winds greater than 35 mph (56 kph), and visibility of less than ¼ mile (0.4 km) for at least three hours. … Travel becomes dangerous when the blowing snow causes whiteout conditions and sky and ground look white.
