Toward a physically and microstructure-based equation for the evolution of the specific surface area in snow
Löwe, Henning
The specific surface area (SSA) of snow is a critical structural quantity that controls snow properties and constantly evolves over time. An accurate understanding and modeling of the dynamical evolution of the SSA is thus of primary importance for snowpack models. For this, we simulate the evolution of randomly generated bi-continuous microstructures that resemble real snow microstructures and investigate the control of the ambient conditions (temperature and temperature gradien) and of the phy
