How is sleet different from hail

Of the three types, freezing rain is often more dangerous to motorists than is sleet and hail. Due to low ground temperature, ice layers on the ground may remain for several hours to several days, creating slippery roads and very unsafe driving conditions. She is especially passionate about reading and writing, although her other interests include medicine, art, film, history, politics, ethics, and religion.

It is formed during strong thunderstorms. Thunderclouds with strong updrafts or upward motion of air combined with high liquid content that produce big water droplets and a below freezing temperature level produce hail. As it grows in size, it falls faster towards the ground.

Its effects can be devastating both to buildings and other structures as well as to crops, livestock, and human lives.

Weather satellites and radar are used to detect thunderstorms that may produce hail, and warnings are issued to prevent incurring serious damage to property and lives. While hail usually occurs in the summer or during warm weather, another solid precipitation occurs during winter, sleet. It is also referred to as ice pellets which are tiny, crystalline balls of ice.

It is smaller than hail and is formed when clouds are warmer than the air below them and when there is only very little updraft.

It does not freeze in the clouds but it freezes in the cold air as it falls down to Earth. Snow can form in the gentle updrafts of stratus clouds or at high altitudes in very cold regions of a thunderstorm. Snowflakes that most of us are used to seeing are not individual snow crystals, but are actually aggregates, or collections, of snow crystals that stick or otherwise attach to each other. Aggregates can grow to very large sizes compared to individual snow crystals. If the riming is particularly intense, the rimed snow crystal can grow to an appreciable size, but remain less than 0.

Graupel is also called snow pellets or soft hail, as the graupel particles are particularly fragile and generally disintegrate when handled. Sleet are small ice particles that form from the freezing of liquid water drops, such as raindrops.
