Die rote Linie im Schneeprofil zeigt den vertikalen Temperaturverlauf in der Schneedecke sowie zuoberst die Lufttemperatur.
Treten Temperaturgradienten ( Temperaturunterschied pro Meter ) von mehr als 5 ° C / m auf, so findet eine ausgeprägte aufbauende Umwandlung statt ( hin zu kantigen Formen und Becherkristallen ).
Hat die Temperatur in der ganzen Schneedecke denselben Wert, was fast nur bei 0 ° C vorkommt, so ist die Schneedecke isotherm.
www.slf.chThe red line in the snow profile shows the vertical temperature pattern in the snowpack and the air temperature immediately above it.
If temperature gradients ( temperature differences per metre depth ) of more than 5 ° C / m exist, prolific faceting occurs ( formation of grains with flat faces and cup-shaped crystals ).
If the temperature is consistent throughout the snowpack – a condition that occurs almost exclusively at 0 ° C – the snowpack is said to be isothermal.
