4.2.6 More snow

New event: Snow

Let's say that in the six days since the initial snowstorm, the following has happened:

  • The old snow has settled to a depth of 14 in (35 cm)
  • There's a layer of surface hoar
  • The SWE has decreased slightly from 1.30 to 1.26 in (3.3 to 3.2 cm) due to sublimation (evaporation of snowpack)
  • The snow-to-liquid ratio (SLR) is ~10:1

Scenario for day 6 after a new snowfall.

We've just received approximately 12 in (30 cm) of new snow.

  • The air temperature is -5°C (23°F)
  • The SLR is ~15:1
  • The SWE is 0.8 in (2.0 cm)
  • The wind was 3 to 4 m/s (6 to 8 kt) when the new snow was falling but has calmed down and is now 2 m/s (~5 kt)
