The vertical residuals show annual variations with amplitudes ranging from zero to 20 mm. These residuals have been filtered slightly for clarity. The vertical movements are not in phase with the east-west seasonal movements. The amplitudes are greatest near the glaciers and in the Highland, but it does not quite fit to an idea of snow loading because the stations go up in the winter time and down in the summer time (phase lag?)
There are no seasonal variations clearly visible in the north component.
