Stockholm county was one of the most affected as the storm Alfrida came to Sweden. The strongest winds measured in the stockholm archipelago, where Swedish the piles had orkanbyar at 37.2 meters per second. A maximum of byvindar in Sweden was measured at Fårö on Gotland and at Örskär in the Village with 38.5 metres. The limit of hurricane force yesterday at 33 metres per second.
” It was an unusually strong storm with orkanbyar. Not least in view of the extent and the large number of trädfällningar. It is similar to a storm we had on January 3, 1954, 65 years ago, which was also unusually strong, ” says Sverker Hellström, klimatolog at SMHI.
much weaker. Maximum wind speed in the county was measured at Tullinge airport vindstation, of 23.9 metres per second.

Hurricanes in the northern hemisphere is called the polarfrontscykloner and is usually much weaker than tropical cyclones, which can be twice as strong in strength. They develop in polarfronten when warm and cold air masses meet.
” No, but it is difficult to say. Our models are pointing in the direction, but rather so that it will become rarer. The storms developed by sharp contrasts between cold and warm temperatures, a warmer climate reduces the breeding ground for severe storms, ” says Sverker Hellström.
