Final answer:
The ANA pattern index is not one of the major teleconnections discussed in lecture or in the IPCC AR4.
Step-by-step explanation:
Of the major teleconnections discussed in lecture or in the IPCC AR4, the ANA (or ANA pattern index) is not one of them. The major teleconnections that were discussed include ENSO (El Niño-Southern Oscillation), NAO (North Atlantic Oscillation), and PDO (Pacific Decadal Oscillation). These teleconnections refer to climate patterns that are linked to large-scale atmospheric and oceanic processes, influencing weather and climate patterns globally and regionally. The ANA (or ANA pattern index) is not commonly mentioned as a major teleconnection in the context of the lecture or the IPCC AR4.
