Icelandic Met Office: Comparision of temperature in Stykkishólmur, Akureyri and ReykjavíkEntry ID: IS-MET_TemperatureStykkisholmur-Akureyri-Reykjavik1950-2007
Abstract: Comparision of temperature in Stykkishólmur, Akureyri and Reykjavík
A comparison of annual temperatures at three stations, Stykkishólmur in the west, Akureyri in the north and Reykjavík in the southwest reveals some inter-station differences.
The first cold interval, the "ice years", was the coldest of the three in the north and east, but the 1979 to 1986 was the coldest in southwestern Iceland. ... Figure 2 highlights this by expressing the variability as 7-year running means of temperature. We see the end of the warm period in 1965 and three cold sub-periods during 1965 to 1971, 1979 to 1986 and 1992 too 1995.
The cold during the ice years was accompanied by persistent northerly winds and an associated maximum extent of the East Greenland sea ice. The air pressure during this period was generally high - the NAO was in a negative phase.
The cold period that started in 1979 was characterised by very low pressure and an extremely positive NAO phase, the NAO phase culminating in 1989 to 1995. The air masses that dominated the weather in Iceland originated over the cold continental areas of Kanada, brought to Iceland by persistent southwesterly winds. In this situation the southwest is anomalously cold compared to the northeast.
