Weather: why has the sky been a little white and cloudy in recent days?

A milky veil has been covering parts of the French sky in recent days. The cause: smoke from the other side of the Atlantic, due to fires in Canada, while the heatwave is making a comeback in France.

After several weeks of gloomy weather, the sun is back in France, with a heatwave forecast for most of the country. But for the past few days, the skies have been less blue, veiled or even a little white, and there's a good reason for this: smoke from fires- not in the Aude region, but in Canada, on the other side of the Atlantic. This is a regular occurrence whenever large fires break out in Canada, a fact already noted in June.

This requires favorable weather conditions, with an"unusually dynamic jet stream over the ocean", as indicated by the Météo-Paris website. A corridor of high-altitude winds linking the United States and Europe, bringing with it the smoke from the Canadian fires that were particularly visible on August 6. This is what tints the sky with a light whitish layer. The smoke from the fire in southern France, meanwhile, is heading for the Mediterranean.

As a result, we're still seeing clear skies, albeit a little paler in color than usual, or more orangey hues at sunrise or sunset. Fortunately, this time the quantities are more moderate and have no impact on air quality in the Paris region.
