The pollen then goes very high up into the atmosphere and then, as it cools down during the course of the day, the pollen grains come down to earth again and at about 6pm they tend to be back at nose level.

The poor air quality is being caused by an area of high pressure which is pulling air carrying particles from Europe towards Britain, and also creating still conditions - meaning local air pollution is not being dispersed.
Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France, likened the phenomenon to the June heatwave in the Pacific Northwest, which scientists concluded would have been 'virtually impossible' without man-made climate change.
Official data from across the UK shows that high pollution levels were also recorded in Yorkshire, including Leeds and Sheffield, and in Kent and Sunderland, while parts of the South East - particularly Essex and Norfolk - were set to see 'very high' levels today.
