A new method for constraining the ocean in coupled system model for long reanalysis and climate predictions

Nansen and Bjerknes scientists have for the first time demonstrated the capability - thanks to an advanced data assimilation method - to constrain ocean variability in key regions (e.g. North Atlantic, Equatorial and North Pacific) of a fully coupled Earth system model just using sea surface temperatures. This result opens new possibilities for a long fully coupled reanalysis dating back to 1850 and test thoroughly the skills of decadal predictions by the Norwegian Climate Prediction model. The research team lead by Dr.

Arctic climatic temperature amplification in the addressed in two resent papers in Tellus

Nansen Center scientists in Bergen and St. Petersburg have in two resent papers in the Tellus addressed the climatic temperature amplification in the Arctic, analysing respectively surface air temperature records and atmospheric modelling simulations results.

Award for most sited climate paper at SpringerLink in 2015

The paper Arctic sea ice and Eurasian climate: A Review was the most downloaded paper published in Advances in Atmospheric Sciences at SpingerLink in 2015. This review paper addressing the linkages between the climate in Arctic and in Europe, North America and Asia has been downloaded more that 1600 times.

Blue-Action: Arctic Impact on Weather and Climate

Blue-Action is a 5-year European project of Horizon 2020 Blue Growth coordinated by the Danish Meteorological Institute with 41 partners. Prof. Y. Gao is a key partner and is leading work package 3.

Blue-Action will provide fundamental and empirically-grounded, executable science that quantifies and explains the role of a changing Arctic in increasing predictive capability of weather and climate of the Northern Hemisphere.To achieve this Blue- Action will take a transdisciplinary approach, bridging scientific understanding within Arctic climate, weather and risk management research, with key stakeholder knowledge of the impacts of climatic weather extremes and hazardous events; leading to the co-design of better services.This bridge will build on innovative statistical and dynamica

VENTILATE: Ventilation and remineralisation in polar and sub-polar regions as indicators for climate change

VENTILATE will evaluate decadal changes  in ventilation of the Nordic Seas (Greenland, Iceland, and Norwegian Seas) and the Arctic Ocean.

The oceans uptake of atmospheric CO2 is connected both to physical and biological processes. This uptake has been very important for the Earths climate, modulating the effect of man-made CO2 since the industrial revolution.

However, with the continuing increase of CO2 in the atmosphere and the observed climate change, it is uncertain how the ocean’s uptake will be affected in the future.

A key knowledge here is the link between the physical processes and the oceanic carbon cycle. To increase our understanding of this link is the overall aim of VENTILATE.

NORTH: NORthern constraints on the Atlantic ThermoHaline circulation

Structure of the Atlantic thermohaline circulation

Den atlantiske termohaline sirkulasjonen kan sies å være Golfstrømmens drivkraft, som en pumpe i den store globale havsirkulasjonen. Når Golfstrømmens forlengelse mot nord driver oppover langs vår kyst, avgir vannet varme til omgivelsene. Det blir avkjølt og tyngre. I De nordiske havene synker vannet ned og returnerer sørover igjen. 

Spørsmålet i dette forskningsprosjektet er enkelt sagt i hvilken grad vi kan si at klimaendringer i De nordiske hav er opphav til globale endringer, eller et resultat av globale endringer.

EuraArc: Impact of Arctic sea ice decline on Eurasian Climate

Link the Arctic sea ice and Eurasian climate

The satellite data over past 30 years indicated that the Arctic sea ice is decling fast. Furthermore, results from the CMIP3 and CMIP5 models showed that the summer Arctic sea ice will disapper at the end of 21st century.

ORGANIC: Overturning ciRculation and its implications for Global cArboN cycle In Coupled models

Overturning Circulation and its imapct on ocean carbon cycle

 

ORGANIC is a fundamental research project integrating mathematic, computational and natural

sciences, and is aimed at advancing our understanding of the climate system and identifying the

uncertainties associated with the future predictions. To do this, ORGANIC applies the Norwegian

Earth System Model (NorESM) to elucidate the variability and main drivers of the ocean conveyor

circulation, a key indicator for climate change. The implications of this variability on the
