What's happened
A plume of Saharan dust, carried by warm southerly winds from North Africa, is expected to reach the UK over the next two days. It will cause hazy skies, vibrant sunrises and sunsets, and deposits on surfaces, especially in England and Wales. Temperatures could hit 19°C, with impacts most noticeable today and tomorrow.
What's behind the headline?
The arrival of Saharan dust in the UK highlights the interconnectedness of regional weather systems and the global climate cycle. While the dust poses no health risks, its visual impact—vivid sunrises and sunsets—serves as a reminder of the Earth's dynamic atmosphere. The dust's movement is driven by storm Regina and high-pressure systems, which funnel warm air from North Africa northward. This event underscores how climate variability influences air quality and surface conditions across Europe. The dust's presence also temporarily affects visibility and outdoor surfaces, but these effects are largely cosmetic and transient. As climate change potentially increases the frequency of such events, understanding their patterns becomes crucial for future preparedness and public awareness.
What the papers say
Sky News reports that the Saharan dust is being carried from North Africa by high-pressure systems and Iberian storm Regina, leading to hazy skies and vibrant sunrises in the UK. The Met Office notes that the dust may deposit on surfaces, especially in England and Wales, and that temperatures could reach 19°C. BBC News emphasizes the natural, long-distance transport of dust and its visual effects, such as deep orange sunrises, while also noting the potential for dust to impact air quality and visibility, especially in southern Europe. The Independent highlights the broader context of dust transport driven by weather systems like Storm Regina and the recent 'Calima' events, illustrating how such phenomena are common but can be intensified by specific atmospheric conditions. All sources agree that the dust poses no health risk but offers a striking visual display and temporary surface effects.
How we got here
The dust originates from North Africa's deserts, lifted by storm Regina and high-pressure systems. It travels thousands of miles on warm air currents, often reaching Europe during late winter and spring. Recent storms in Iberia have intensified dust transport, which is a natural, recurring phenomenon linked to seasonal weather patterns and global atmospheric circulation.
