Warning, (in Swedish), level 1, Sweden
Wind is measured with a wind gauge, normally at 10 m above ground. The wind is specified by direction (degrees) and speed (m/s) respectively. The wind direction tells you where the wind is coming from. 360° means that the wind is coming from the north, 270° means the wind is coming from the west and 0° means calm.
The wind that is specified is a 10-minute average wind. Wind measurements are normally carried out every three hours. From our automatic stations, unexamined data often comes in every hour
Where are these measurements taken?
In the column on the right there are maps you can zoom in and out of which show the temperature stations in operation as of September 2008.
The station network has changed over the years, so if there is no station marked in the area/place you are interested in, it is possible that we still have data for this particular place. The selection of station therefore takes place in consultation with our meteorologists.
How is the data compiled?
The results are presented in the form of tables, maps or diagrams, according to your requirements. Observations of wind direction, wind speed and gusts, average and extreme values, can be presented as time series and monthly tables. Daily and annual variations can also be presented.
The number of observations of different temperatures, in absolute figures or as a percentage, divided by the amount of months, can be ordered in a frequency table, for example wind speed and wind direction. We also have frequency tables where the wind speed is shown in relation to the wind direction, for example speed-direction.
Wind roses are an efficient way of visualising a dominating wind direction and speed distribution at a specific location. Wind roses can be drawn up for the whole year or for seasons and for wind in connection with precipitation.
We can analyse extreme weather events, such as storms, and calculate return times for high wind speeds. The development of storms can be animated or presented in a report or illustrated by using pictures.
