SNOWGLACE: The Changing Arctic Cryosphere: Snow and Sea Ice Impact On Prediction and Climate Over Europe and Asia

Climate impact of Arctic sea ice and snow cover

Arctic summer sea-ice extent exhibits a sharp declining trend, and the induced atmospheric warming at high latitudes in autumn has potentially important consequences for the climate of Europe and Asia. On the other hand, North America, Europe, and East Asia have experienced anomalously cold winters with record high snowfalls during some recent winters. The autumn snow cover over Eurasia is increasing, while in spring, the snow decline at high northern latitudes is the largest cryospheric change in terms of spatial extent.

NACLIM: North Atlantic Climate: Predictability of the climate in the North Atlantic/European sector

Impact of Arctic sea ice and sea surface temperature

 

NACLIM aims at investigating and quantifying the predictability of the climate in the North Atlantic/European

sector related to North Atlantic/Arctic sea surface temperature (SST) and sea ice variability and change on

seasonal to decadal time scales. SST and sea-ice forcing have a crucial impact on weather and climate in

BlueArc: Impact of ‘Blue Arctic’ on Climate at High Latitudes

Arctic sea ice impact on climate

 

The global warming is enhanced in the Arctic where surface air temperature has increased twice as much as the global average in recent decades, also called Arctic amplification. Arctic warming implies melting of sea ice, but its dynamic-thermodynamic response is neither straightforward

 

or necessarily linear, nor is the response of the atmosphere to sea ice

reductions. Satellite observations (1979 to present) show that the Arctic

Study of the trend and variability in the surface air temperature in the Arctic

Prof. Ola M. JohannesssenNansen Fellow Prof Ola M. Johannessen and colleagues at the Nansen International Center in St. Petersburg and Uni Research have published the paper Surface air temperature variability and trends in the Arctic: new amplification assessment and regionalisation in Tellus A.

GREENICE: NordForsk Impact of Future Cryospheric Changes on Northern Hemisphere Climate

Interaction between the climate and the changing cryosphere

 

The overarching goal of the project Impacts of Future Sea-Ice and Snow-Cover Changes on Climate, Green Growth and Society

(GREENICE) is to learn more about the interaction between changes in climate and changes in sea-ice and snow cover. There is large

uncertainty associated with anticipated future changes, in particular with regard to the extent, timing, and impacts of such changes.

ARCPATH: Arctic Climate Predictions: Pathways to Resilient, Sustainable Societies

Focus on changes that will happen in the near future, with the overarching goal of fostering responsible and sustainable development.

A key objective in ARCPATH as a multidisciplinary project is to use downscaled predictions to better understand and assess, and thereby reduce and prepare for, risks with shipping in sea-ice infested  and potentially stormier waters, with extreme weather conditions, in a region largely unprepared to cope with major environmental accidents such as oil spills at sea.

InterDec: InterDec - The potential of seasonal-to-decadal-scale inter-regional linkages to advance climate predictions

InterDec aims at understanding the origin of decadal-scale climate variability in different regions of the world and their linkages, using observational data sets and through coordinated multi-model experiments.

1. We will investigate inter-regional and inter-basin linkages on sub-seasonal to interannual time scales, achieved mainly through atmospheric teleconnections. At present, the role of air-sea interactions among different latitude belts in the Atlantic and Pacific, and of stratosphere -troposphere coupling in these linkages has not been clarified.

Sail-off Meeting of Nordic Center of Excellence at the Nansen Center

The sail-off meeting of Nordic Center of Excellence Arctic Climate Predictions: Pathways to Resilient, Sustainable Societies (ARCPATH) took place at Nansen Environmental and Remote Sensing Center (NERSC) during April 11. and 12. 2016. ARCPATH is funded by the Nordic Council and includes nine partners from Norway, Denmark, Sweden and Iceland in addition to Canadian, Chinese, Russian and US partners.

IMOS: Isfjorden Marine Observatory Svalbard

IMOS will support long-term synergistic cooperation between Russian and Norwegian scientists working in Svalbard by establishing a joint marine plankton observatory in Isfjorden.

Isfjorden is the largest fjord system in Svalbard, located in the dynamic transition zone between warm Atlantic and colder Arctic climate regimes. We will expand the existing time series on seasonal hydrography and plankton dynamics in ice-free Adventfjorden (since 2009) and seasonal ice covered Billefjorden (since 2001) with an observatory located in the mouth of Isfjorden close to Barentsburg and an observatory in the deep Karlskronadjupet, close to Longyearbyen.

Predictability of Arctic/North Atlantic climate”, research project of the Centre of Climate Dynamics: PRACTICE

The overall objective of PRACTICE is to establish a basis for interannual to decadal prediction of Arctic/North Atlantic climate.

The Bergen community has key competence and infrastructure in
the observed and modelled circulation and dynamics of the North Atlantic/Nordic Seas/Arctic
Ocean climate system, including both an established Earth System Model and an advanced
operational ocean-ice forecasting system focused on the high northern latitudes and Arctic sea ice.
There have been several recent developments that corroborate the above and further
suggest that the Bergen community is well positioned to take on the challenge of climate
