A remarkable meteorological phenomenon captured the attention of onlookers in Manchester last Saturday, as a dust devil tornado swept through Great Ancoats Street. This swirling column of dust, rising approximately 30 metres high, momentarily halted traffic and left pedestrians staring in disbelief. Witnesses struggled to comprehend the sight, with one bystander exclaiming, “What the…? What the hell? There is a tornado in the middle of Manchester… that’s crazy.”

Among the captivated crowd was violinist Adam Riding, 30, who described his initial reaction as one of shock. “It was this dark cloud and at first I thought it was an explosion, but I didn’t really hear any noise. I froze,” he recounted to Manchester Evening News. As the dust devil escalated, he instinctively recorded the moment on his phone, noting that the entire spectacle lasted only a minute.

The phenomenon wasn’t exclusive to Manchester; similar incidents have been reported across the UK, particularly in areas experiencing unusually hot and dry weather conditions. A dust devil was also recently observed in Warwickshire where it managed to lift hay and debris into the air for about 30 to 40 seconds. These formations, typically harmless, appear more frequently during heatwaves and can occasionally pose risks if they grow large enough to impact surrounding environments.

A Met Office meteorologist provided clarification on the nature of dust devils, explaining their formation process. Unlike tornadoes, which form from thunderstorms, dust devils arise from irregular temperature contrasts on the ground, leading to rotating columns of warm air mixed with dust and debris. “Dust devils grow upwards from the ground, rather than down from clouds,” the meteorologist noted, elaborating that they tend to last only a few minutes due to their reliance on surface temperature for sustenance.

Earlier this year, a dust devil in Prestatyn, Wales, was also filmed during Storm Franklin, underscoring the phenomenon’s sporadic nature across the UK. Observations show that dust devils can range significantly in size, from a few metres in height to towering over 1,000 feet under exceptional conditions, often appearing in desert and semi-arid climates where the ground is exceptionally hot.

In Essex and Cambridgeshire, similar debris-lifting events were reported amidst hot weather, initially misconstrued as mini-tornadoes. This misunderstanding is common, as dust devils often exhibit dramatic behaviour capable of uprooting tents or breaking garden structures. Caution should be exercised, as they can inflict minor injuries if individuals are caught in their path, although they usually dissipate quickly due to the cooling of air intake from their base, limiting their duration and intensity.

Engagement with such natural phenomena serves as a reminder of the capriciousness of weather and its varying manifestations. As witnessed in cities like Manchester, the extraordinary spectacle of a dust devil can both awe and bewilder, standing as a testament to the ever-changing dynamics of our atmosphere.
