Notably, there is no Robert-Asselin time filter used in the barotropic portion of the integration. 857 857 858 Upon reaching $t_{n=N} = \tau + 2\ Delta \tau$ , the vertically integrated velocity is time averaged to produce the updated vertically integrated velocity at baroclinic time $\tau + \Delta\tau$858 Upon reaching $t_{n=N} = \tau + 2\rdt \tau$ , the vertically integrated velocity is time averaged to produce the updated vertically integrated velocity at baroclinic time $\tau + \rdt \tau$ 859 859 \begin{equation} \label{DYN_spg_ts_u} 860 860 \textbf{U}(\tau+\rdt) = \overline{\textbf{U}^{(b)}(\tau+\rdt)} … … 1152 1152 and Asselin filtering is done in \mdl{dynnxt}. 1153 1153 1154 1155 1156 % ================================================================ 1154 % ================================================================
