3.2 Total Precipitation
As with surface air temperature (SAT), total precipitation (TP) depends on surface
type and terrain
elevation (see Fig. 9). Similarly to SAT, the terrain of Iceland only induces a weak wave pattern
in the larger-scale northeast to southwest gradient in the GCM ensemble mean field of TP during
the 1961–
90 control period, resulting in about 0.5 mm day 1 lower mean
