According to forecasts, it will be -6 degrees Celsius during Donald Trump’s inauguration ceremony, where more than 200,000 spectators are expected to attend. According to American media, it will be the coldest ceremony since the inauguration of Ronald Reagan in 1985 (-14 C°).
“Polar vortices” are very strong winds blowing near the pole in winter, located in the stratosphere (the atmosphere is made up of the troposphere, in which we live, then the stratosphere just above).
The expected temperatures “could be fatal” for people who are outdoors, the meteorologist warned.
-If the link between global warming and heat waves is very direct, the behavior of winter storms is governed by complex atmospheric dynamics, which are more difficult to study.
In early January, the United States suffered one of these storms in the center and east, which caused the death of at least five people and caused hundreds of flight cancellations. Temperatures dropped to -18°C and tens of thousands of people were left without electricity.
