Test of a simple two-layer parameterisation to simulate the energy balance and temperature of a snow pack

摘要: Reasonably simple yet realistic modelling schemes simulating the heat and mass balance within a snow pack are required to provide necessary boundary conditions for meteorological hydrological models. An improvement one-layer energy model (UEB, Tarboton etal., 1995) is proposed better simulate surface temperatures and, as result, snowmelt. The modified scheme assessed against measured data from WINTEX field campaign during spring 1997 in northern Finland, compared with results complex multi-layer scheme. show that separation of representation into two layers soil layer enables more simulation well temperature. two-layer yielded comparable internal processes whenever was carried out under similar forcing. use sub-scheme or models, tool spatially-variable snowmelt seasonal cover.
