Book Description
Dynamic normal mode initialization (DNI) is applied to low and high resolution versions of the AFGL global spectral mode. This scheme is tested against the operational nonlinear normal mode initialization (NMI) procedure using both adiabatic and diabatic forms of the model tendencies. The DNI-based forecasts are comparable in accuracy to the NMI-based forecasts, with small differences between the adiabatic and diabatic versions of each. DNI initial conditions were somewhat more damped in the divergence fields than were the NMI fields. This is believed to be due to the frequency response characteristics of the DNI's forward-backward time scheme, which tended to partially damp resolvable wavelengths.

Book Description
Recent studies have demonstrated a link between ozone changes caused by human activities and changing UV levels at the Earth's surface, as well as a link to climate through changes in radiative forcing and links to changes in chemical composition. This book draws together key scientists who provide state of the art contributions on the variable ozone layer and the interplay of longwave and shortwave radiative interactions which link ozone, the climate and UV issues.
