vísbending um þróun farvegarins úr breiðu, óafmörkuðu rennsli yfir í
skilvirkar rásir. Einnig kann að vera að í upphafi hlaupsins hafi töluvert vatnsmagn
safnast upp í vatnsgeymum undir jöklinum sem ekki tóku mikinn þátt í því að flytja
rennsli.

Mælingar á vatnshita í Skaftá benda til þess að hlaupvatnið sé við eða mjög nærri
frostmarki þegar það kemur undan jöklinum. Þetta bendir til þess að

in an overall
cold bias, compared with station measurements. To test, whether this is due to the HARMONIE
model core or the external surface scheme, biases of 2-m temperature from SURFEX are com-
pared with biases of temperature projected from the lowest two model levels to 2 mAGL. It is
found that the negative temperature biases are due to shallow inversion layers near the ground,
which are introduced

This is also the case with
cyclones in all three sectors. Cyclones in the eastern or western sector are also strongly affected
by the presence of central cyclones. In both sectors, cyclones tend to move east, unless there are
cyclones in the neighbouring sector, in which case pressure tendencies are reversed.

are being used
to analyse the occurrence of dry spells,
both from historical data and from
climate scenario simulations. There is
significant year-to-year variability in the
pattern of rainfall, and this variability is
assessed based on the range of values
from individual years in the analysis.
