Earlier this month, sand from the North African desert altered the colour of sky over parts of Europe.
Sand and dust particles from the Sahara Desert are expected to affect Europe on Sunday, including the Russian city of Saint Petersburg, according to forecast by the EU’s Copernicus Earth Observation Programme published on 20 February.
A substantial amount of the Saharan dust will sweep through the northern part of Europe, with most of it blanketing Spain and southern France, according to the forecast.
At the beginning of February, a major influx of dust and sand that was brought by wind from the Sahara Desert turned the sky over parts of Southern Europe orange, causing a massive air pollution spike.
Meteorologists explained later that the effect was caused by a major storm in Morocco that swept through the north-eastern part of the country at a speed of around 100 km per hour, blowing out clouds of sand and carrying them north.
