Overview
- CAMS forecasts the plume passing over southern England and the English Channel this afternoon at higher altitudes, with brief wet deposition possible where it intersects rain.
- The agency indicates a potential secondary crossing over southern England on Wednesday based on latest model runs.
- The aerosol layer is dominated by Saharan dust with some smoke from seasonal biomass burning in Equatorial Africa moving across the North Atlantic.
- ‘Blood rain’ occurs when falling raindrops scavenge airborne dust and leave a thin residue on surfaces after evaporation, according to the Met Office.
- Scientists expect the most noticeable effects to be dusty cars and hazy reddish or orange skies, with limited health concerns and only localized air-quality impacts where concentrations are higher.
