Title: Understanding the origin of the solar cyclic activity for an improved earth climate prediction
Authors: Turck-Chièze, Sylvaine cturck@cea.fr, Lambert, Pascal1
Source: Advances in Space Research. Sep2007, Vol. 40 Issue 7, p907-914. 8p.
Subjects: Ecology, Solar activity, Solar cycle, Helioseismology
Abstract: Abstract: This review is dedicated to the processes which could explain the origin of the great extrema of the solar activity. We would like to reach a more suitable estimate and prediction of the temporal solar variability and its real impact on the Earth climatic models. The development of this new field is stimulated by the SoHO helioseismic measurements and by some recent solar modelling improvement which aims to describe the dynamical processes from the core to the surface. We first recall assumptions on the potential different solar variabilities. Then, we introduce stellar seismology and summarize the main SOHO results which are relevant for this field. Finally we mention the dynamical processes which are presently introduced in new solar models. We believe that the knowledge of two important elements: (1) the magnetic field interplay between the radiative zone and the convective zone and (2) the role of the gravity waves, would allow to understand the origin of the grand minima and maxima observed during the last millennium. Complementary observables like acoustic and gravity modes, radius and spectral irradiance from far UV to visible in parallel to the development of 1D–2D–3D simulations will improve this field. PICARD, SDO, DynaMICCS are key projects for a prediction of the next century variability. Some helioseismic indicators constitute the first necessary information to properly describe the Sun–Earth climatic connection. [Copyright &y& Elsevier]
