Gridded hail-size forecasts are produced by sampling hail sizes from the predicted distribution and applying them in rank order onto the column total graupel
The thing about this late cold spell in April, with its graupel
showers and snow-peaked hills, is that it'll make us all the more grateful for the warmth of summer, whenever that eventually begins.
Weather experts say graupel
is a kind of hybrid frozen precipitation, sometimes referred to as "snow pellets".
Many of the terms are endearing, such as anvil zits, cloud streets, horse latitudes, knuckles, mamma clouds, steam clouds and, of course, graupel
floats in the thickness of some pines near the dump:
These assumptions, which are reasonable in warm cloud modeling, appear to be not so adequate for mixed phase clouds, where interactions between different categories (cloud water, rain water, crystal ice, graupel
, hail) have to be considered.
The size distribution of small graupels
(minigraupels), we studied, followed closely the log-normal distribution curve (Table 5) and does not correspond to much larger graupel
sizes sampled in Germany.
A strong evening wind from the west carries in a snow squall, with accumulations of 10 centimetres in 10 minutes, first as graupel
, then hail.
There are miles-wide floating bergs; slow-flowing, earth-sculpting glaciers; balls of hail as big as your fist; tiny white pellets called graupel
The Vaisala algorithm tended to produce deeper layers of wet snow where the EC algorithm reported graupel
and dry snow (Reid et al.
The dreaded cumulonimbus is a cumulus cloud that has taken on great vertical and horizontal extent and has a fibrous texture at the top: this is the manifestation of rain, graupel
, hail, and ice.
Not snow, gale force winds nor a rare phenomenon called graupel
could deter 94 of them from taking part in the Ladies' Winter Alliance at Longley Park this week.
