  • Orsaken bakom variationen i Arktis istäcke klarlagd 2019-10-31 Det är det svårspådda vädret, inte isens reflexionsförmåga, som ligger bakom varför istäcket vid Nordpolen varierar så mycket från år till år, även om trenden på lång sikt är att isen minskar på grund av Jordens uppvärmning. Det visar ny forskning från Stockholms universitet och Max Planckinstitutet för meteorologi i Tyskland.

  • SWERUS-C3 - first leg is coming to an end 2014-08-18 We just started the engines for the last transit down to Barrow, and so the first leg of this expedition is coming to an end. The last several days we have more or less parked ourselves in the ice north of Barrow. The majority of the research programs on board has been winding down and no more sampling was done. Our meteorology program have however continued as usual; we even managed to perform two transects across the ice edg. We also had an interested mesoscale cyclone pass right over us few days ago.
  • SWERUS-C3 work around the clock 2014-08-12 Oden 2014-08-09. After spending over a week under a constant fog, we have experienced binary weather the last few days . either fog or spectacularly clear. The temperature goes up and down between -2C, and ice sticking on everything when it is foggy, or +2C; Not very much variation it may seem, but I can assure you it feels very different.
  • SWERUS-C3 – challenging weather conditions 2014-08-12 Oden 2014-08-03 New month; new report! Ever since we left Bennett Island behind us on the 29th we have been moving in a very stubborn fog...
  • SWERUS-C3 going into the ice again 2014-07-31 We have now passed from open water into the ice again. Yesterday and today we have circled Bennett Island (Picture 1), the first land we have seen since we left the Norwegian coast. Just as a perfect timing, yesterday also was a beautifully sunny day (Picture 2); sunshine, dark ocean, azure blue melt ponds and glittering white snow. It can't get much better! Today, however, the weather closed in again and we are now fumbling along in really tough ice with fog with zero visibility and no real good idea how to get ourselves in the right direction. We still have plenty of time for the remaining work, so it not very urgent; just a bit frustrating.
  • SWERUS-C3 has passed its midpoint 2014-07-31 Now SWERUS has passed its midpoint; at least we had a midpoint dinner a few days ago. Very nice food, good company and high spirits! In general we eat very well on board, if maybe a bit too much. For a little over a week now, we have been in open water, but now we are heading east towards the ice edge again. There's a little island - Bennet Island - that we are supposed to round and it looks like it is right in the "marginal ice zone" right now.
  • Latest update from the Arctic Cloud Summer Experiment (ACSE) 2014-07-18 We have now rounded Severnaya Zemlya and entered the Laptev Sea; right now we are "balancing" on the outer edge of the shelf. The route from the Kara Sea to here took us through some pretty sturdy ice and so we lost some time, which we are now trying to catch up on.
  • Mobilisation onto Oden 2014-06-11 Many scientists from Stockholm University have spent several weeks packing all the instruments and equipment that will be needed for the expedition to the Arctic this summer.

  • The weather has changed 2014-04-23 Around our world, many feel that the weather is changing, in different ways. The question is: Is is something that we just think we experience or is the change actually happening, is it real? A new research study presented at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago now support the idea that something is not quite as it was before. One of our scientists, Professor Michael Tjernström, made a comment about this on Swedish Television (SVT) this morning.
  • Intervju i SR: Nytt hot mot ozonlagret 2014-04-14 Det var en framgångssaga för klokt samarbete mellan forskare, politiker och industri när Montrealprotokollet förbjöd användning av klor- och brominnehållande freoner. Avtalet fanns på plats bara ett år efter att man hade förstått hur de angrep ozonet. Nu dyker nya kemikalier upp, kusiner till freoner, som man inte vet var de kommer ifrån, och som är lika aggressiva som de som förbjöds. Caroline Leck är professor i kemisk meteorologi på MISU. Hon kan ozonlagrets historia på sina fem fingrar och är idag oroad. Programledare: Per Gustafsson.

  • MISU scientists investigate gravity waves in the atmosphere over northern Sweden 2013-12-04 As part of an international collaboration called GW-LCYCLE, scientists from MISU are currently performing light detection and ranging (lidar) measurements at Esrange, northern Sweden. The lidar observations complement experiments that are conducted aboard the German research aircraft FALCON. The comprehensive measurement campaign focuses on the excitation and propagation of gravity waves in the atmosphere. Northern Sweden provides excellent opportunities for such studies as the Scandinavian mountains are a prominent source of mountain waves, a particular class of gravity waves.

  • Saharan dust detected over Stockholm during Midsommar 2013-06-28 Mineral dust from northern Africa was transported all the way to Sweden and caused the blurry white sky that we could observe over Stockholm during Midsommar. In contrast to the small air molecules whose interference with sunlight causes the sky to be blue, mineral dust particles are much larger and scatter light equally efficient at all visible wavelength. This causes the sky to turn white during such events – despite a lack of clouds.
  • This summer’s first displays of noctilucent clouds have now been photographed by MISU’s cameras 2013-06-12 Since the summer of 2004 we run an automatic camera on the top floor of Arrhenius Laboratory in Stockholm.

  • Arctic summer sea ice extent controlled by atmospheric transport 2013-05-06 The retreat of the summer sea ice in the Arctic region is one of the most dramatic signs of the ongoing climate change. Although the ice cover is steadily decreasing it also shows a large variability from year to year. In a new study, published in the scientific journal Nature Climate Change, researches at Stockholm University have examined the variability of the Arctic sea ice. They concluded that warm and humid winds from southerly latitudes towards the Arctic in spring are important for the amount of sea ice later in the summer.

  • Elephant seals helped scientists to resolve a 30-year mystery about Antarctic bottom water formation 2013-04-09 Scientists, with the help of elephant seals, have solved a 30-year mystery surrounding the formation of the Antarctic bottom water, a dense cold water filling in most of the ocean deep basins. The formation and circulation of Antarctic bottom water is a key process of the global ocean circulation and therefore of the earth’s climate.
