the Swedish meteorological and hydrological institute has been flagged for very high throughput in the county of Halland and southern Småland, sweden. Rescue workers are struggling along with the property owners to build barriers to protect against flooding.
Many people testify that they had never seen anything like it. And some are asking if it is related to the mild winter. Richard Alpfjord Wilde, hydrologist dropped at the Swedish meteorological and hydrological institute, says of the animal world that we had been able to avoid this situation, if there had been a snow of the year.
The winter is characterised by south-westerly winds, and several low pressure systems, with rainfall from the Atlantic ocean across the south west of Sweden.
"That's also the reason why this is so, the flows are high right now," says Erik Kjellström, professor of climate science at the Swedish meteorological and hydrological institute, to the Network. High-flow will become more and more common in the field
According to him, it is difficult to link the current weather to climate change. However, in general, increases the risk of periods of heavy rainfall, when we get more mild winters. And väderinstitutets of the scenarios shows that flows are high in the long term, will become more and more common in the region.
" if you Look at the hydrology of the scenarios increases, and on the occasion of the high flow rates, with the more severe extremes in the longer term, in the south-west of Sweden. However, in the north of sweden, where the heavy flows in the rivers associated with the smältsnö, you can see a slight decrease, " says Erik Kjellström.
there are other kinds of extreme weather, thus, longer periods of time, with similar, intense weather conditions, the increase of global warming. An example of this is the dry and hot summer of 2018.
" We can't determine the date to be exactly the kind of winter is going to be more and more common in the future. However, it is clear that it is getting warmer, which means more water vapor and more precipitation. Then, there is a risk for even worse flow. It will apply to all of the winter, no matter if it's a mild winter or a colder winter, " says Erik Kjellström.
