Once again 🌬, #dust flows inland from the Mediterranean near Derna — flipping the usual S→N pattern. These repeats hint that shifting pressure & heat 🔥 contrasts aren’t just quirks. 🌍 When rare flows return this soon, the #climate signal gets louder. 🛰Meteosat @eumetsat.int ✂️Visualized @zoom.earth

A striking blend of smoke and #SaharanDust streaming over the Med, #wildfires in Spain & Portugal feeding thick plumes, merging with airborne #dust from North Africa. The result? A murky, hazy layer stretching across southern #Europe. A vivid reminder of how multiple crises can collide in our skies.

A compact dust vortex formed over Algeria’s Adrar region — likely driven by intense surface heating and weak low-level cyclonic flow. These mesoscale dust spirals aren’t common, but in summer Saharan setups like this, they reveal just how dynamic "still" deserts can be. 🛰 @eumetsat.int ✂️ @zoom.earth

A #DustStorm from Sudan sweeps across the Red Sea🌬🌊, reaching near Saudi shores. Driven by strong desert winds, this plume impacts marine and coastal #AirQuality, alters solar radiation, and plays a role in regional climate dynamics. 🛰Meteosat @eumetsat.int ✂️Visualized @zoom.earth

Enjoyable day working in Peru with #OSINFOR

We often hear about #airpollution from wildfires in North America and southern Europe but fires in the UK are less studied. My latest piece for @theguardian.com on the impacts of moorland fires. www.theguardian.com/environment/...

Lots of fun with students along the Holderness coast a week or so back. It’s well-studied for a reason.

Orienteering in the Lakes last weekend. Glorious + ticks

A huge smoke plume from the fires in Manitoba, Canada, a week ago, which advected over Europe in the past few days (see 18 May image), is already over Asia today – well captured by the Met-12 (MTG) True Colour RGB (see 20 May image), via @inorbitivan.bsky.social

On MAY 07, 2025,🛰satellite @eumetsat.int Meteosat-IODC detected a massive plume of #dust💨 moving off the coast of Africa, born from a storm far inland. This astonishing animation shows a Saharan dust storm moving over the west coast of #Africa over to the Atlantic Ocean💨🌊 📊Processed in @zoom.earth

Cool to watch the launch of #biomass this morning @esa.int @science.esa.int #sheffield

This is what illegal ‘selective’ logging in Peru’s rainforest looks like. Locating and identifying illegal logging is resource-heavy and dangerous but @granthamcsf.bsky.social researchers have developed tech to track it in near real time by spotting subtle changes in the rainforest canopy... 1/2

That danged haboob is spawning additional haboobs! Haboobs on top of haboobs! Attn @sheffielddust.bsky.social @wisc-satellite.bsky.social @aerosolwatch.bsky.social et al.

Interested in using behavioural science to tackle pollution? I'm advertising a fully-funded interdisciplinary PhD project at the Uni of Sheffield with @sheffielddust.bsky.social & Darpan Das (Uni of York), to start Sep 2025. Application deadline 4th April! www.findaphd.com/phds/project... #PsySciSky

Windblown dust has heavy economic consequences, according to a new analysis by Daniel Tong @georgemasonu.bsky.social, @tomgillpredicts.bsky.social, & others. Story by @virginiagewin.bsky.social 🧪

Great to see this out. Important work by Abdulkareem as part of his PhD at Sheffield (with Dave, myself and Mike) www.sciencedirect.com/science/arti...

More than a threat…. Fall in overseas students fuels threat to English universities despite rise in fees www.theguardian.com/education/20...

UTEP news release about our study of the economic effects of windblown dust www.utep.edu/newsfeed/202...

Well done @tomgillpredicts.bsky.social and others…. Great paper here: www.nature.com/articles/s41...

Two important components of the past weekend. #orienteering #doughnuts

And Great to meet long time 'virtual' colleague @sheffielddust.bsky.social Don't forget you can check out your "local" Air Quality Stripes at..... airqualitystripes.info Inspired by @edhawkins.org Climate Stripes

🧪 A fact: Yesterday in #Iceland , in addition of volcanic activity , there was quite some #highlatitudedust activity in the southern coast. So, given that there is not major dust activity in the Sahara desert, Iceland is these days the largest sources of aerosols into the Atlantic Ocean 1/2

🧪 Now that the higher resolution image arrived (MODIS), it is easier to make out what is dust and non-dust just by eye (or a trained eye, 😀) . Unfortunately, no images from the Sentinel/Landsat. @sheffielddust.bsky.social

Snowy Sheffield morning.

Monday PM PhD supervision…

🕐One more week to apply to be an Editor of Area!🕐 We are looking for human & physical geographers to join our team. All editors are supported by a full-time Managing Editor who helps with finding reviewers, freeing time for engagement with authors & papers. See below for more⬇️ tinyurl.com/49u4ec2m

What you really don’t want to see when you arrive at a lecture theatre….

Autumn in full force. Quick walk around Agden Reservoir above Bradfield nr Sheffield

My birthday treat was a trip to Halifax. More exciting than it sounds (honest).

Had some fun in Wiltshire and the Forest of Dean a few weeks back

Last weeks effort at some 'war paint' for Orienteering somehwere in the Forest of Dean - with bobble# 2. It was a seriously wet mudfest.

Where I work. #Sheffield #Geography Brutalist Masterpiece (now with LED lights). I'm hoping for a blue/white flashing display when #spurs win the league. I can hope 😜
