Type-3 Saharan dust events

Some episodes were classified as Type-3 SDE, at times when a high pressure centre is established over NW Africa and SW Europe. The strong flows of the anticyclone carry dust particles from western parts of the Sahara northward along the coastline or over the eastern Atlantic, at the mid-latitudes the dust-laden air mass moves eastward due to the westerlies. This type of Saharan dust transport is responsible for the observed dusty events in western Europe: in Ireland and in Britain.

The longest (ca. 6500 km) and least common dust pathways are associated with the Type-3 SDEs from the western parts of Sahara across the eastern Atlantic and western Europe.
