The heat wave that hit Canada also reached Europe

In the past few days some of the highest temperatures ever have been recorded in the Nordic group. In Lapland, the thermometer exceeded 33 degrees for the first time since 1917

The heat wave that has hit Canada in recent days has arrived in Europe and hit the group of Nordic countries, namely Denmark, Norway, Sweden, Finland and Iceland, bringing the thermometers up to 34 degrees in some areas very close to Arctic circle.

In Finland, 2020 was the hottest year in the country's history, but 2021 could be even more so. In fact, according to reports from the Finnish Meteorological Institute, June has broken all temperature records since meteorological measurements began in 1844 and experts expect a further increase in the coming summer months. In Sweden, June was also marked by particularly high temperatures, positioning itself as the third warmest ever faced by the Nordic country.

In Lapland, on the other hand, the authorities recorded a peak of 33.6 degrees, marking the second warmest day of the country since 1917, when the thermometer reached 34.7 degrees. While in Norway, temperatures exceeded 34 degrees in Saltdal, a county close to the Arctic Circle, marking, for now, the highest temperature measured this year in the country.

Michael Reader, professor of meteorology at Monash University in Australia, explained in The Conversation magazine how the climatic events occurring on the European continent are directly linked to those occurring in North America. According to Reader, the heat wave that arrived in Canada was generated by an atmospheric disturbance called the "Rossby wave", caused by a minimum temperature spike in the Western Pacific near Japan. From there, it gave birth to another wave that spread to Europe. "It's like plucking a guitar string," Reader said in an interview with the Guardian, "the disturbance arrives in North America, amplifies itself and produces a large system of high pressure in the central part of the atmosphere" which spreads along the currents as far as Europe.
