FL180: 270/25-45KT, but 26015KT by the NE-coast, -29
Overview of weather systems:
1000 km S of Cape Farewell is an extensive 980 mb low. Over Greenland is a 1038 mb high.
Near surface winds:
N-ly or variable wind, 05-25 KT.
Cloud heights/visibility/weather:
BKN/OVC at 1000-2500 FT in the N-part and occasional snowshowers with poor visibility. Widely FEW/SCT and good

are photographs, maps and graphs that show the main results of measurements
and analyses that are available, now two weeks after the event.
Width of fracture line: 800 m
Vertical drop: 350 m
Runout length beyond the lake shore: ~1000 m
Volume: ~30–50 million m³
Estimated duration of the slide: 20 seconds according to seismographs
Travel time of tsunami across the lake: 1–2 minutes

from 9°C on the east coast to 16°C in the interior in
north-eastern part of Iceland. Precipitation is highest in the glaciated
highlands of south Iceland with annual values in excess of 5000 mm of annual
accumulated precipitation on the highest glaciers and in general with high
values ranging from 1000 mm up to 3000 mm in mountainous areas. Lower values
with less than 1000 mm prevail north

a systematic com-
parison of results to observed precipitation has been carried out. Un-
dercatchment of solid precipitation is dealt with by looking only at
days when precipitation is presumably liquid or by considering the
occurrence and non-occurrence of precipitation. Away from non-
resolved orography, the long term means (months, years) of observed
and simulated precipitation are often

The recognition of geophysical precursors
to volcanic activity is a primary challenge
in volcano monitoring. That challenge was
successfully met by scientists at the Icelandic
Meteorological Offi ce (IMO) before the
1 November 2004 eruption of Grímsvötn, a
subglacial volcano beneath the Vatnajökull
ice cap, Iceland (Figure 1).
Seismic and geodetic precursors were prop-
erly recognized
