What is Saharan dust and how does it get to the UK?

A weather phenomenon predicted by forecasters is causing red dust to land on cars and stunning sunsets and sky colours.

Saharan dust clouds are made up of a mixture of sand and dust from the Sahara Desert, a huge area of desert covering most of North Africa.

And at this time of the year, sand from the Sahara is blown towards the UK by southerly winds, the Met Office reports.

The phenomenon coincides with an improvement in the weather and a rise in temperatures, and often produces stunning orange coloured skies and sunsets - an Instagram photographer's dream.

The Met Office said on Twitter: “Low pressure is feeding southerly winds into the UK from the Canaries, allowing Saharan dust to be drawn north too. You may notice dust deposits on cars and colourful sunrises/sets next few days.”

The distance travelled is because once the dust is lifted from the ground by strong winds, the clouds of dust can reach very high altitudes and be transported worldwide, covering thousands of miles.

The Met Office says: "In order for the dust to get from up in the sky down to the ground, you need something to wash it out of the sky - rain. As raindrops fall, they collect particles of dust on the way down.

"Saharan dust is relatively common in the UK, often happening several times a year when big dust storms in the Sahara coincide with southerly wind patterns. In certain weather situations, Saharan dust can also affect air pollution and pollution levels."
