) noted that Iceland had a maritime
climate that was much milder than its position on the globe might suggest. In
data from 1981–2010, Iceland annual average temperatures ranged from 6°C at the
south coast to 3°C at the north coast, with a substantially colder highland
interior. In comparison with the latitudinal average for the same period, the
coastal temperatures in Iceland are 8–10°C warmer

model setup are typically too large by up to an order of magnitude.
This, combined with strong forcing at the model boundaries, results in a systematic spatial bias in
low-level wind speed, with too strong winds in coastal regions, and too weak winds in the interior.
Figure 5 shows a comparison of average wind speed at 10 mAGL between the WRF model and
station measurements. Model data is interpolated
