“We are still missing some data, but the trend is unmistakeable, extreme weather is becoming more common in Sweden,” said meteorologist Lennart Wern to daily Dagens Nyheter (DN).
Recent downpours and heavy rains over western Sweden is but one example of a trend showing more extreme weather according to the so far unpublished report by SMHI.
In a new report Wern has collated information about the rainiest 24 hours from the country’s all weather stations in a year and then builds a series of data that will span the whole of the twentieth century until present day.
“And for the Götaland region we see a definite rise. It is that part of the country where it is increasing the most,” Wern told DN.
The torrential rain that struck western Sweden on Monday and has left many households flooded is just the most recent example of a change in the weather, according to the report.
The rains have put a huge strain on emergency services in the area. Many roads have been blocked, local radio was hit by the weather and a large number of house owners saw their cellars flooded.
“This is a reflection of how climate change may affect us in the future,” said Lennart Olofsson of he County Council in Västra Götaland, to news agency TT.
The regional climate scenarios show how the average temperatures in the region will rise by five or six degrees by 2100.
The period will also see a lot more precipitation, a rise of about 20 percent, and an increase in heavy downpours, according to the report.
And meteorologists say that the low-pressure area, which is causing the current downpour, is moving in over Sweden today, not losing in force as it travels.
"There is still a lot of power in this low pressure area. Generally they die out as they travel, but that does not seem to be the case with this. It will keep going,” said Kjell Lund, meteorologist at SMHI to dally Aftonbladet.
“It looks there will be as heavy downfalls as we have seen in the Gothenburg area and the rain will continue most of Tuesday, “ said Lund to the paper.
SMHI has issued a class one warning for many areas of Sweden over Tuesday.
