Climatology and historical snowcover of the Big Level Plateau, Gros Morne National Park, Newfoundland.

摘要

The daily climatological record including snowcover water equivalent (SWE) was estimated for the Big Level Summit Plateau (BL), Gros Morne National Park, western Newfoundland, for the 1962--1999 study period. This was accomplished using widely known statistical techniques, i.e. multiple linear regression and mean ratios, linking the Big Level Autostation (1993--1999) record with the nearby low lying coastal stations records through the climate elements mentioned above. Physically based relationships were added for the snow model, which was based on the reconstructed climatological elements (temperature, wind speed and precipitation).; An anthropogenically induced warmer climate would lead to much thinner snowcovers existing during shorter periods, with snow seasons having reduced snowfall and increased rainfall values. The thinnest seasonal snowcovers of the recent past such as in the 1981 snow season could become above average if the IPCC climate change projections become reality. (Abstract shortened by UMI.)
