Ever noticed how snow will disappear without melting? Even in sub-freezing weather, the frost on your car or the snow bank will get smaller. How does this happen? It’s called sublimation. Bob explains …
Figure 1. Equating the rate that ice molecules leave the crystal surface to the rate of heat transfer to the surface from surrounding air is the basis for an equation predicting snow sublimation rate.
Sublimation, the direct transfer of frozen water to the vapor phase, is a thermodynamics problem: it occurs because snow crystals are made of water molecules, which, statistically, will leave the snow in some number (...
When the air is colder than freezing, sublimation happens when molecules of ice and snow absorb so much energy that they skip the liquid form and jump straight to a gas.
For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor (gas) in the air without first melting into water.
In a new study, published in the Bulletin of the American Meteorological Society, scientists have filled longstanding gaps in the poorly understood process of sublimation, which is the process by which snow transforms...
Snow sublimation occurs when snowpack is lost to the atmosphere, turning directly into water vapor without melting first, bypassing the liquid water phase entirely. Snow sublimation may remove as little as 10% or as m...
Significantly more sublimation during blowing snow events calm events.
Snow sublimation is an important component of the snow mass balance, but the spatial and temporal variability of this process is not well understood in mountain environments. This study combines aprocess-based snow mo...
When the air is colder than freezing, sublimation happens when molecules of ice and snow absorb so much energy that they skip the liquid form and jump straight to a gas.
