Abstract

Four processes are identified as determining the initial interception of falling snow by forest during storms: delivery of snow particles from the airstream to the forest; true throughfall of particles to the forest floor; impaction and adhesion of particles to foliage and branches; and cohesion of particles into masses of snow. Delivery and impaction processes seem amenable to aero-dynamic analysis; adhesion of particles and cohesion both depend on air temperature and foliage roughness. Promising leads for laboratory and field research on aerodynamic and thermodynamic factors influencing interception are described.
