1 Introduction
Iceland (103 000 km2) lies in the North Atlantic Ocean, just
south of the Arctic Circle. Due to the warm Irminger Cur-
rent, the island enjoys a relatively mild and wet oceanic cli-
mate and a small seasonal variation in temperature. The av-
erage winter temperatures are around 0 ◦C near the southern
coast, where the average

also Catalogue of Icelandic volcanoes. Jökulhlaups can be of various sizes, where the maximum
discharge and volume of floodwater spans orders of magnitudes. The largest
jökulhlaups in historic times, (e.g. outbursts from Mýrdalsjökull caused by
Katla eruptions), have had a maximum discharge on the order of 100.000 m3s-1,
comparable to the discharge of the Amazon river. The rate of discharge

that prior to August 1992, when a new SIL-station
(skh) was added to the network southeast of Eyjafjallajökull, all stations were situated
west of the volcano (Figure 1). Furthermore a second station (snb) was added in February
1993 about 45 km to the ENE. The addition of these two stations has undoubtedly had
substantial influence on the detection threshold and accuracy of the system near

In autumn season the precipitation
decreased the most in the western regions of all countries (by 6-11%).

Windspeed conversions
The Icelandic Meteorological Office uses the SI (Systeme Internationale d´Unites) unit metres per second (m/s) in windspeed measurements. Here you can convert between different units of windspeed. Type a number into a textbox below and then click outside it. Please note that Beaufort-values are between 0 and 12.
