The dynamics of geophysical phenomena are multi-scale in nature and the interaction between different scales makes the flow complex. Therefore, the system of coupled partial differential equations used in weather and climate models becomes complex which generally can only be solved numerically.The accuracy of the predictions obtained by numerical integration of these partial differential equations depends on model formulation, physical conservation principles, hypothesis and approximations used in their formulation and accuracy of numerical method used for the integration. The advanced dynamical core solvers used in atmospheric and oceanic general circulation models comprise of designing of dynamical equations of conservations, latitudinal –longitudinal mesh, discretization method, temporal integration scheme, parallelization, integration on supercomputing platforms etc. The challenges in the designing and development of advance dynamical core are to achieve required accuracy by their formulation and computational scalability while retaining required accuracy. The basic objective of this program is to bring together leading experts in the field to elucidate the challenges, practical considerations and opportunities and review the present state of understanding. In addition, another aim of this program is to encourage students and young researchers to take up advanced research problems related to dynamical core design.
