UA new cloud of dust coming from the Sahara is rising towards France. It has been extending over the south of the country since Friday before rising and evacuating to the east from Tuesday, October 29.
According to Copernicus modeling, the Nord and Pas-de-Calais should be avoided by this cloud. Concentrations will be greater in the south of the country and in Auvergne-Rhône-Alpes, on the Swiss and Italian border.
On the other hand, according to Vincent Guidard, head of the “Atmospheric Pollution: Surface, Modeling, Assimilation” team within the National Center for Meteorological Research (CNRM), a research unit of Météo France and the CNRS, the dust would go up to in England via the Nord and Pas-de-Calais and even as far as Scandinavia from the night of Friday October 25 to Saturday October 26.
The presence of sand in the sky can impact air quality and cause problems for people with breathing difficulties.
The consequences are also meteorological: the sand could notably lower the temperature, the sun's rays being slowed down by the cloud of dust.
In terms of health, the diameter of Sahara dust is greater than that of fine particles coming from human activity (wood heating, combustion engine vehicles), such as PM2.5 and PM10. They therefore have more difficulty penetrating into organisms.
