Changes in a shallow snow cover subject to a temperate climate
Observations were carried out on each significant layer of the snow cover at Ottawa (lat. 45 degrees 24'N., long. 75 degrees 43'W.) on the thickness of the layer, and the density, grain size distribution and degree of bonding of the snow in each layer. A logarithmic dependence on time was...

| Summary: | Observations were carried out on each significant layer of the snow cover at Ottawa (lat. 45 degrees 24'N., long. 75 degrees 43'W.) on the thickness of the layer, and the density, grain size distribution and degree of bonding of the snow in each layer. A logarithmic dependence on time was found for the layer thickness, and the density and grain size distribution. The product of layer thickness times the corresponding snow density was found to be constant when no melting occurred. On a effectué des observations sur chaque couche importante d'une couverture de neige à Ottawa (lat. 45 degrees 24'N, long. 75 degrees 43'O). On a enregistré les modifications chronologiques de l'épaisseur des couches, de la densité de la neige, de la dimension des cristaux et de leur ré partition. L'assemblage des cristaux, après le passage au tamis, a fait l'objet d'une étude. Des relations logarithmiques ont été établies en fonction du temps é coulé. On s'est apercu que le produit de l'épaisseur d'une couche et de la densité correspondante de la neige est constant lorsque la neige ne fond pas. Peer reviewed: Yes NRC publication: Yes |
