The numbers are for how many days it snows a year and the amount of snow on the ground. The present report justifies the need of a European research project to develop an advanced procedure for deriving snow load on structures, taking into account climate change projections, and to set up a new European snow load map based on this procedure. In between snow events, roofs may lose snow mass due to either wind scour or by melting from building heat loss. The UK National Annex replaces the ground snow load map and some of the roof coefficients for buildings to be constructed in the UK.
