Trends in annual maximum snow water equivalent in Norway (1914-2008)
MetadataShow full item record
In this report, the large number of annual snow data measured annually by the power production companies and reported to NVE, is analysed for the detection of possible temporal trends. There are no indications of significant trends in the mean annual SWE in Norway when data is pooled nationwide or for regions. When investigating temporal trends as a function of altitude for single stations, significant trends, both positive and negative, occur.
