INFLUENCE OF EXPLOSIVE VOLCANIC PHENOMENA UPON DIRECT SOLAR RADIATION IN ROMANIA
Journal Title: Present Environment and Sustainable Development - Year 2009, Vol 3, Issue 3
Abstract
On its way through the terrestrial atmosphere, direct solar radiation is subject to a diminishing (extinction) phenomenon caused by the constituent gases and aerosol. Extreme geophysical phenomena, such as explosive volcanic eruptions, can severely increase the quantity of aerosol in the atmosphere, intensifying the extinction phenomenon and causing a dramatic decrease in direct solar radiation. Analyzing the deviations of annual means from the multi-annual mean for six stations, this paper shows the influence of El Chichon’s and Pinatubo’s explosive eruptions upon direct solar radiation in Romania.
