Robinson, Walter A. Mitas, Christos Michail 2015-09-28T14:52:18Z 2015-09-28T14:52:18Z 10000-01-01 2003 2003 Finally, the generalized model is scrutinized in terms of its normal, adjoint, optimal and singular modes. It is found that the modes of the empirically modified model are more stable than the ones of the barotropic model. Also the modified barotropic optimal modes are more difficult to excite than their barotropic counterparts. These results are in accordance with previous studies that found that barotropic dynamics may not quantitatively describe LFV. The singular modes of the modified operator have very similar patterns but explain less variance than the barotropic ones. This is consistent with the difficulty in detecting optimal patterns in observations. Finally, we find that the modified barotropic operator is more normal than the classic barotropic one, and thus less variable. Made available in DSpace on 2015-09-28T14:52:18Z (GMT).
