Kolmården

In early medieval times it was seen as a major obstacle in land travel between the regions, and so the Baltic Sea was largely used instead.

Together with the extensive forests of Tiveden and Tylöskog to its west, Kolmården formed a major impediment for travel between the Swedes in Svealand to the north and the Geats in Götaland, which caused peaceful and warlike interaction to be conducted by water.

Kolmården has a climate that is a hybrid between maritime and continental with some differences between lower, coastal parts, and the higher forested hills.

The Kolmården weather station is located at 159 metres (522 ft) above sea level and therefore has some orographic lift, resulting in increased rainfall for the region.

The elevated nature Kolmården has an effect on rainfall east of it, splitting many fronts in two, creating a micro version of a rain shadow.
