Wild conditions

31st January 2008


Conditions were quite wild for our observations today. We found a fair bit of graupel within the snowpack. Graupel (or soft hail as it is sometimes called) is the name for firm, rounded pellets of snow/ice. These pellets are formed through the riming of individual snowflakes in humid, sub-zero conditions. Graupel can sometimes collect in certain areas. Windslab deposited on top of these areas can be very unstable as the graupel can act like ball bearings.
