Description: An initialization of a spectral formulation of the primitive equations using a diagnostic divergence is tested for a global model. The initial conditions are generated from a developing baroclinically unstable wave. A semi-implicit time scheme is developed and tested along with the usual explicit method during the course of the experiments. Results show a relatively small effect of a divergent initialization on the ensuring integrations. The semi-implicit method shows a tendency to smooth out high frequency oscillations in local tendencies.
