Abstract
A number of studies on the relationship between solar activity and various terrestrial phenomena, especially in the climatic, oceanographic and biological fields, have been carried out over several decades. In this work we analyse the shorter oscillations of solar activity as well as those recognized in the evolution of some natural fluctuating phenomena such as mean sea level evolution and the space/time succession of coastal pine stands. In particular, we analyse the sunspot series (Wolf relative number series) which is considered an index of solar activity and has been observed since 1700, together with the series of the mean sea level variation from four oceanographic stations in Poland (Swinoujsce), France (Brest) and Italy (Venezia and Cagliari) and the series of the space/ time succession of coastal pine stands of southern Sardinia. Because the sea level evolution and the space/time succession of the investigated coastal pine stand fluctuate in intensity, an analysis of these fluctuations and their possible correlation with solar activity was considered of great interest in contributing to explain the various interactions between natural fluctuating phenomena and other problems relating to the forecast of the climatic evolution.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
