Summary
A chronology and some comments about the occurrence of ‘dry fogs’ i.e. clouds of volcanic aerosols trapped in the planetary boundary layer (PBL) are reported. The dry fogs have severely affected the biosphere, and they also had local climatic effects affecting the terrestrial albedo. In the most severe cases the fog persisted for months and obscured the sun, in the lesser ones a mist persisted for a few days and the sun was seen as ‘weak’ and the moon with a red halo. The volcanic aerosols were trapped in the PBL in the warm season, when the atmosphere is particularly stable over the relatively cold Mediterranean waters and the Azores Anticyclone causes the absence of winds.
