Whether this event is an example of an internal climate mode or is externally forced, such as by enhanced solar effects, is presently under debate. (realclimate.org)
Other links between climate modes of variability and Antarctic coastal winds can produce a similar coastal wave ocean response. (usclivar.org)
A recent paper by Han et al. (2016) reviews our current state of knowledge about spatial patterns of sea level variability associated with natural climate modes on interannual - to - multidecadal timescales. (judithcurry.com)
