PHOTOS: Saharan dust from Africa reached Crete
A plume of Saharan dust from Africa reached Crete on Thursday, resulting in hazy skies across the island.
This dusty sky is not all that unusual for Crete.
The dust in the atmosphere can also lead to more interesting sunset and sunrise pictures.
This mass of dusty and very dry air forms over the Sahara Desert from late spring into early fall is known as the Saharan air layer (SAL).
Plumes of dust typically move off the African coast every three to five days during this time.
The SAL is usually located 5,000 to 20,000 feet above Earth’s surface and travels due to strong winds.
