Måler temperaturprofiler over hele Bergen i dag

Submitted by Lasse Pettersson on 7. January 2016 - 12:20

Nansensenteret har siden 2011 målt temperaturprofilen i luften opp til 1000 meter over Geofysisk institutt på Florida i Bergen sentrum. Instrumentet som er det eneste av sin type i daglig drift i Norge og gir i disse dager nyttig informasjon om temperaturinversjonen over Bergen sentrum. Inversjonen bidrar til at luftkvaliteten i flere deler byen blir helseskadelig høy.

Følger utviklingen av temperaturinversjon og luftforurensing i Bergen

Submitted by Lasse Pettersson on 5. January 2016 - 12:44

Siden søndag kveld har det vært temperaturinversjon over Bergen. Slike temperaturinversjoner er de meteorologiske forhold som oftest fører til høy luftforurensing i Bergen. Meteorologene varsler fortsatt stabilt vær fram til torsdag, så vi kan forvente oss at luftkvaliteten er og vil forbli dårlig i dagene framover. Gjelder dette bare luftkvaliteten på Danmarksplass og i sentrum eller påvirker slike inversjoner også luftkvaliteten andre deler av kommunen?

Submitted by Pierre Rampal on 28. October 2015 - 13:35

Sea Ice Modelling

The Nansen Center is pleased to announce that a new sea ice forecasting platform called neXtSIM-F is now up and running for the Barents and Kara Seas.

Forecasts are generated daily using neXtSIM-F on a 3km Lagrangian grid. neXtSIM-F is based on the sea ice model neXtSIM which is currently being developed at NERSC by the sea ice modelling group.

Investigating the possible causes for the recent warming hiatus

Submitted by Lasse Pettersson on 25. September 2015 - 14:36

The IPCC stated in their latest assessment report that the global warming hiatus was attributable in roughly equal measure to natural variability and reduced trends in external forcing. A detailed study involving over 2000 years of model simulations has demonstrated that according to the Norwegian Earth System Model, there is no evidence that forcings errors play a significant role in explaining the hiatus. These results has been addressed in two papers lead by Nansen Center scientists Drs. Stephen Outten and Peter Thorne recently published in Journal of Geophysical Research.

Ny rapport: Norge må forberede seg på stigende havnivå og høyere stormflo

Submitted by Lasse Pettersson on 9. September 2015 - 5:00

Klimaendringene gjør at havet kan stige opptil 30 centimeter på Sør- og Vestlandet innen 2050 og 80 centimeter mot slutten av dette århundret. Også i Oslo vil havnivået stige dersom dagens utslippsutvikling fortsetter, og risikoen for oversvømmelse ved stormflo øker over hele landet.
