first forecast hour, model simulations tend towards the values at the end of the previous run, but
especially in the interior of the island, some significant differences remain.

For 2-m air temperature and 10-m wind speed, this is illustrated in Figure 5, based on average
diurnal cycles, calculated separately for grid points

ESC statement on L’Aquila sentence
The European Seismological Commission (ESC) as a Commission of the
International Association of Seismology and Physics of the Earth’s Interior
(IASPEI) endorses and adheres to the IASPEI Press Release on the L'Aquila
sentence (http://www.iaspei.org/news_items/laquila_IASPEI_press_release_final.pdf

lake in a volcanic caldera in the interior of the Vatnajökull ice cap (Björns-
son, 1988). Jökulhlaups from Grímsvötn have been known since at least the fourteenth
century (Þórarinsson, 1939, 1974). In the beginning of the twentieth century there were
about ten years between outbursts but the floods diminished with time and became
more frequent. After a catastrophic, rapidly rising flood caused

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
