Rain or drizzle which freezes on contact with a surface within a subfreezing air mass gains the preceding adjective "freezing", becoming the known freezing rain or freezing drizzle. Slush is a mixture of both liquid and solid precipitation. Frozen forms of precipitation include snow, ice crystals, ice pellets (sleet), hail, and graupel. Their ...
Unlike hail or sleet, graupel is soft and can be crushed easily in your hand, and is sometimes called "soft hail." It is also usually smaller than hail, with a diameter of around 0.08-0.2 inches.
Because freezing rain does not hit the ground as an ice pellet (called "sleet") but still as a rain droplet, it conforms to the shape of the ground, or object such as a tree branch or car. This makes one thick layer of ice, often called "glaze". Freezing rain and glaze ice on a large scale is called an ice storm. Effects on plants can be severe ...
Hail can also undergo "dry growth", in which the latent heat release through freezing is not enough to keep the outer layer in a liquid state. Hail forming in this manner appears opaque due to small air bubbles that become trapped in the stone during rapid freezing. These bubbles coalesce and escape during the "wet growth" mode, and the ...
Freezing rain does not bounce when it hits the ground like sleet, and it does not run off as warm rain does. Due to its resemblance to ordinary rain, its onset may catch some off-guard until it ...
If we can’t have snow, we might as well learn what all that other frozen precipitation is.
Rain or drizzle that freezes on contact within a subfreezing air mass is called "freezing rain" or "freezing drizzle". Frozen forms of precipitation include snow, ice needles , ice pellets , hail , and graupel .
Recent precipitation in Dallas-Fort Worth has been nearly all sleet, which weather service experts say is “quite rare.” Here’s what to expect next.
