The measurement of MMN in our research was obtained from the average brain wave induced by the deviated stimulus minus the average brain wave induced by the standard stimulus, located in the 100-250 ms negative phase wave after the appearance of the beginning auditory deviant stimuli, which was different from highly repetitive standard sound stimulation.
On the background of a reduced meridional temperature gradient, these conditions favour a more frequent occurrence of meridional flow regimes like negative phase of AO in early and mid-winter which may persist into late winter.

Figure 7 shows a complete inner sphere that has a positive phase, and two spheres of negative phase cut open to show that inner sphere.
The 'Three-Month Outlook', issued in late October, noted that, "El Nino moderately increases the probability of the positive phase of the NAO in late autumn and early winter and the negative phase of the NAO in late winter.
One can manage the protection settings for Group Phase Overcurrent (OC), Negative Phase Sequence (NPS), Earth Fault (EF) and Sensitive Earth Faults can be managed through auto reclose mapping, protection curves and directional element configuration.
