SITES is a national research infrastructure for terrestrial and limnological field research open to all scientists. SLU is main coordinator for SITES and host the SITES secretariat. SLU has five participating stations in SITES: Asa Research Station, Grimsö Wildlife Research Station, Lönnstorp Research Station, Röbäcksdalen Field Research Station and Svartberget Research Station
Snow records in Röbäcksdalen and Svartberget
The weather this winter around Umeå in northern Sweden has so far been erratic. Both November and December were unusually warm with little snow, but in January the temperature fell, it started to snow, and multiple snowstorms occurred during a period of just a few days.
Snow situation at Röbäcksdalen - a record for the season
Röbäcksdalen Field Research Station is measuring snow depth since 2010. So far this season, 75 cm of snow have accumulated at the station, which is the deepest snow cover since the recording started. Usually, the highest snow depths are measured later in the season which shows the magnitude of the current situation and that there is a possibility for more snow to come before this winter is over.
Almost a meter of snow at Svartberget – a record for January
At Svartberget research station, about an hour drive inland from Umeå, the snow depth increased with over 60 cm during the period with several snowstorms in January, which added onto the already existing snow cover.
Svartberget has measured snow depth since 1980 and the record so far is from 1988 when 113 cm was recorded. A lot of the snow that year fell in February and March. The accumulated 97 cm of snow this January is the deepest ever recorded so early in the season, but the most astonishing is in how short time the snow assembled. It is quite troublesome to think that a lot more snow might still fall.
The local newspaper refers to old farmer’s traditions, which says that half of winter’s snow should have arrived by now. However, data from previous years at Svartberget show that half the amount of snow usually has arrived by Christmas time and that the maximum snow depth is in the beginning of March. The same data supports the likelihood that another 10-20 cm of snow will fall before the winter is over. However, the variation between years is large and climate change makes it difficult to predict the weather, especially in the past years.
