In order to better estimate the earth climatic variations at scales corresponding to decennia or centuries it appears more and more important to understand the internal origin of the solar magnetic cyclic activities together with the evolution of the internal solar rotation profile It is the only way to be able to predict how they will evolve in the future The seismic techniques are totally adapted to this knowledge and an enriched information will allow to interpret the solar global variations as irradiance luminosity at different wavelengths and will measure temporal global mode characteristics which must be linked to the total magnetic fluxes ldots Our main objectives are to predict the characteristics of the coming solar cycles and to determine if there is different origins for the longer solar cycles or if it is only a temporal evolution of the eleven cycle 22 years which produces grand minima or maxima SDO is well adapted to progress on the convective zone with increased resolution in comparison with the SoHO mission it will allow to improve the 11 year solar cycle predictions In complementarity we consider very important to get a general description of the dynamics of the solar radiative zone which contains the main part of the solar mass and to understand the interconnection between magnetic fields of the radiative zone and of the convective zones Such information stays today poorly known even SoHO results on the solar radiative zone through acoustic and gravity modes are very promising to pursue this investigation In this
