    Citizen scientists help bringing water to the weather models

    Citizen scientists help bringing water to the weather models

    Due to the sars-cov-19 pandemic, this year's citizen science project have been postponed. Even though it seems that it is dificult for Norwegian skiers to stay at home, we cannot give them the excuse to seek out the snow. If you want to get involved when we are up and running again, you can contact the Harald Sodemann.
    Harald Sodemann is working on improving the weather models. One thing he and his colleagues think can be improved is how water in the atmosphere is treated, to understand where it is coming from. To do this they need observations, and to get these observations, they ask skiers in the Norwegian mountains to take snow samples. For where better to gather samples of precipitation than the rainy Norwegian mountains. And who better to gather these samples, than skiers that prefer to go where no other people would think about going.

    Før og etter hockeykøllegrafen – med Øyvind Paasche

    Før og etter hockeykøllegrafen – med Øyvind Paasche

    «Det var eit liv før hockeykurven også», seier Øyvind Paasche, seniorforsker og seniorrådgiver ved NORCE og Bjerknessenteret.
    Hockeykurven, Hockey stick graph, Hockeykøllegrafen, – kjært barn har mange namn. Namneopphavet er openbart om du ser på den, ei temperaturlinje gjennom dei siste 600 åra som først går svakt nedover før den får ein knekk oppover på 1900-talet – som gjer at den ser ut som skaftet og bladet på ei hockeykølle.
    Den dukka opp i 1998 i tidsskriftet Nature, og fekk stor betydning for klimaforskinga som felt. Men korleis var det før den kom, kva hendte då den dukka opp, og kva betydning har den fått seinare?
    Øyvind Paasche tek oss med på gjennom hockeykøllegrafens historie – ei reise han sjølv har teke del i. Episoden er produsert av Andreas Hadsel Opsvik. Musikken er Lee Rosevere - Arcade montage, gjennom Creative Commons by-3.0.

    Storm tracks – A conveyor belt of warm moist air

    Storm tracks – A conveyor belt of warm moist air

    Professor Camille Li works on storm tracks, the warm, moist conveyor belt that deliver storm after storm to us here in Western Norway and the British isles. Learn how these storm tracks works, how they will change and the research Camille Li and her colleagues are conducting at the Bjerknes centre for climate research.
    Our host, the NERSC researcher Stephen Outten and editor and associate professor Ingjald Pilskog, talk with Camille Li about why we are getting wet here in northwestern Europe.

    neXtSIM - The next generation of ice forecast

    neXtSIM - The next generation of ice forecast

    Einar Örn Ólason is working on sea ice forecasting and improving how sea ice is modelled in the future generations of earth system models. Learn how we will improve our predictions of what is going on in the high north and how this gives us a better understanding of our future. Learn about neXtSIM the future of sea ice prediction.
    Our host, the NERSC researcher Stephen Outten and editor and associate professor Ingjald Pilskog, talk with Einar Ólason about a model that means more for you then you know.

    Improving weather prediction in the Arctic

    Improving weather prediction in the Arctic

    Weather models are made primarily for making good weather forecasts in the mid-latitudes, i.e. Europe and north America. They are also made to be able to calculate forecasts fast enough to be helpful on computers that are not as fast as the current computers. Therefore we have used a lot of short cuts that are not physical. PhDs as Marvin Kähnert are working on improving the models in the Arctic and introduce more physical correct assumptions.
    Our host the NERSC researcher Stephen Outten and editor and associate professor Ingjald Pilskog talk with Kähnert about the problem and what is done to fix it.

    Kronprinsen på tokt til Antarktis

    Kronprinsen på tokt til Antarktis

    Nadine Steiger var i vår med på Kronprins Haakon til Antarktis. Norges nye isbryter var der nede for å studere isen og livet rundt i havet.
    Elin Darelius er en av våre fremste forskere på Antarktis og isen der.
    I denne episoden får du høre hvorfor vi reiser til andre siden av jorden for å forske på is.
    Våre programledere Ellen Viste og Ingjald Pilskog leder samtalen.
    Episoden er tatt opp hos UiB i Media City Bergen.
    Den er redigert av Ingjald Pilskog, førsteamanuensis i naturfag ved lærerutdanningen ved Høgskulen på Vestlandet og formidler ved Bjerknessenteret for klimaforskning.
    Musikken er av Lee Rosevere - Arcade Montage. Creative commons lisens B.Y. 3.0
