The heatwave affecting large parts of Europe is known as an Omega block because it takes the shape of the Greek letter, with a bulge of hot air in the middle and cooler air either side, an expert says.
“It’s drawing warm air up from North Africa, from the Sahara, and that’s why we have this really intense heat,” said Clair Barnes, a climate scientist at Imperial College in London, quoted by Reuters.
It’s very slow moving and it means there’s kind of no wind, no breeze for respite.
