More Severe Weather Events Now Receiving Names in Europe

Babet, Hans, and Tuesday's yellow warning for Floris – it's just a selection of named bad weather in recent years. SMHI notices that more and more are being named. Like this Karl-Heinz we had last week. It may not have been named before, says Emelie Karlsson, meteorologist at SMHI.

The reason why more severe weather conditions have been named in recent years is that only storms were previously named, while today, severe weather with thunder, rain, and snow is also named.

The definition of a storm is that it must blow 25 meters per second and at Karl-Heinz, the wind was not sufficient to name it, but it was done anyway due to the high precipitation amounts, says Emelie Karlsson.

The Swedish Meteorological and Hydrological Institute also sees that there is greater cooperation between countries in Europe. When the United Kingdom named the week's storm Floris, Sweden chose to follow it.

We would probably not have named it if it had come directly to Sweden, since the consequences for Sweden were not expected to be large enough. Now there was already a name from the United Kingdom and then we use it.

It is the country where the severe weather begins that names it. More and more storms began to get names from when the storm Gudrun ravaged Sweden 20 years ago. Today, even more weather systems are given assigned names.

It becomes a bit more coordination, says Emelie Karlsson.

However, there is a risk that more severe weather in Sweden gets established names.

There is a problem if it does not give any consequences at all. When the next severe weather comes, which can actually lead to major disruptions, the risk is that people will not believe that anything will happen that time either, says Karlsson.
