Prosjekt
Proxy assimilation for reconstructing climate and improving model (PARCIM)
The main objective of PARCIM is to create the first online millennium-long paleo-climate reanalysis, using modern data assimilation, model, and wealth of paleo-proxy archives.

Seashells to hold the reins of climate models
Since 1900 the North-Atlantic has oscillated between warm and cool periods of a few decades. The century long record is too short to show why. Climate models and old seashells will extend the series to the Viking age.
During the last 120 years the surface temperature of the North Atlantic Ocean has oscillated up and down for a few decades at a time. The sea was warmer in 1930–1965 and after 1995, cooler in 1900–1930 and 1965–1995. Corresponding shifts can be traced in the weather in countries surrounding the Atlantic.
That temperatures have gone up and down several times, suggests that natural mechanisms make the Atlantic oscillate. But, this is a rocking cradle of the slow type.

Pioneering subseasonal-to-seasonal prediction of regional climate and extremes through hybrid AI–physics modelling
Society needs reliable predictions to be able to prepare for extreme events like the storms Hans, Amy and the recent heatwaves in Europe. The researcher from the Nansen Environmental and Remote Sensing Center and the Bjerknes Centre will lead the Bjerknes Centre’s new project aimed to develop a climate prediction system for the period between two weeks and one year.
Global Responses and Drivers of the Tropical Pacific Zonal SST gradient Trend
Our climate models say one thing. Observations of the Pacific Ocean show something else. Why?
That is one of the great unresolved questions in today's climate research – and the starting point for one of the Bjerknes Center's new strategic research projects, which has been named GRADIENT.
