But by observing this Friday afternoon the "pale white" color which enveloped Paris and part of northern France, the meteorologist understood that it was not just a whim of the weather.

But the consequences of the monster fires ravaging the American West.

"If you look at the fire smoke simulation map, you can see very clearly that the compact plume of smoke rising over the American West was carried by upward air currents," crossed the Atlantic and reached part of France and Great Britain ”explains the forecaster, a specialist in extreme weather events.

How can these ash particles, suspended in the atmosphere, cross the Atlantic?

"They are transported to us by strong and regular high altitude currents coming from the west," explains Guillaume Séchet.

It's pretty much the same process that happens when we find Sahara sand deposited on the hood of our cars.

When Australia was ravaged a few months ago by bushfires of unprecedented magnitude, researchers from the American space center at NASA were categorical: the fumes from the fires had ended up circling the entire planet. planet.

Soot deposits had even been spotted as far as South America, in Chile.
