Exempel på graupel

• 70% of the rain water came from the melting of graupel and hail.

• If the graupel layer was an inch or more, the snow from this storm would likely be avalanche.

• A graupel or a frozen raindrop may become the initial stage of a much faster growth.

• When this process continues so that the shape of the original snow crystal is no longer identifiable, the resulting crystal is referred to as graupel.

• Graupel was formerly referred to by meteorologists as soft hail.

• Convectional precipitation, typically thunderstorms, often forms rapidly and frequently drop graupel or hail.

• The strongest backscatter comes from hail and large graupel (solid ice) due to their sizes.

• Frozen forms of precipitation include snow, ice needles, sleet, hail, and graupel.

• This process forms "graupel", or snow pellets, as the droplet continues to accumulate on the crystal.

• Ice crystals have a preference to form hexagonal structures by deposition, but can form odd shapes in the presence riming or aggregation into graupel.

• Graupel is found mostly in regions of weak updrafts.

• This scheme uses five different classifications of cloud water: liquid cloud water, cloud ice, rain water, snow, and hail/graupel.

• The process is called "riming" when super-cooled cloud droplets attach to ice crystals in the formation of graupel.

• Many schemes use at least three categories: cloud ice, graupel, and snow.

• Droplets freeze upon impact and can form graupel.

• However, graupel is easily distinguishable from hail in both the shape and strength of the pellet and the circumstances in which it falls.

• Graupel forms fragile, oblong shapes and falls in place of typical snowflakes in wintry mix situations, often in concert with ice pellets.

• Graupel tends to compact and stabilise (weld) approximately one or two days after falling, depending on the temperature and the properties of the graupel.
