Sleet is completely frozen rain drops and hail is formed from graupel falling in a storm cloud, collecting water and then being pushed back up by the updraft and the water it just collected freezing to form another layer of ice. The key difference is that hail is formed from thunderstorm updrafts and sleet is not.
Sleet is formed when ice crystals fall as rain that freeze before it hits the ground. Hailstones form when strong winds blow raindrops back upward to the top of where the temperature is freezing. Then, the raindrops freeze into small pieces of ice. This process might happen several times where many layers of ice may build up. Once the hailstones are too heavy and the wind can blow them back up, the hail falls to the ground.
This is frozen rain, which can be part of an ice storm. (Sleet is rain that freezes into ice pellets as it falls.)
well there is differnt sizes of the hailstones
It soon then becomes powdered snow and sometimes makes sleet or hailstones too.
Actually they are the same; sleet is frozen rain, or ice pellets. This is not to be confused with FREEZING rain, which is rain that freezes near the ground level if it is colder than above. Sleet is already frozen when it hits.
A hailstorm is classified by the size of the hailstones. The size of the hailstones are determined by comparing the hailstones to different objects, like a penny or nickel or even sometimes a baseball.
No, hailstones are not round. They come in different shapes and sizes becasue they are so rough.
sleet
Its different every year
Rain, snow or sleet formed by the condensation of water vapour
Both. Hail is typically formed in the summer by thunderstorms, where the upper atmosphere gets really cold. Sleet is frozen rain formed in the winter usually, where snow melts, then re-freezes.
There are three precipitation forms that are collections of ice.1) In the US, frozen ice pellets are called sleet. This consists of melted snowflakes that are refrozen and fall as small pellets of ice, rather than freezing rain (glaze).2) The form graupel or "soft hail" consists of ice that accumulates on falling snowflakes. This is encapsulated snow.3) Layered ice, sometimes in clumps, is hail. Hailstones form through repeated cycles of liquid coating and freezing, almost always in thunderstorms.
