Sea height anomaly fields from the altimeter constellation, are used in this study.
Although there are other factors controlling
the sea height anomaly, it is assumed here that most of its variability is due to changes in the depth of the main thermocline and of barotropic origin.
The sea height anomaly (SHA) represents the deviation of the sea height with respect to its mean.
In this page, we present four daily maps:
sea height anomalies, sea surface temperature, altimeter - estimate of the depth of the 26 °C isotherm and TCHP.
These maps can be used to identify warm anticyclonic features, usually characterized by
sea height anomalies and a depth of the 26 °C isotherm larger than their surrounding waters; and to monitor regions of very high (usually larger than 90 kJ cm - 2) TCHP.

This visualization shows side by side comparisons of Pacific Ocean
sea surface
height anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.
In general, indices of the annular modes are based on either 1) the leading principal component (PC) time series of gridded geopotential
height anomalies at a given pressure level or 2) approximations of the leading PC time series of geopotential
height anomalies using differences between
sea level pressure
anomalies at stations in middle and high latitudes.
Now, since 2007, at the
height of the global warming scare tactics about arctic
sea ice, the antarctic
sea ice extents
anomaly CONTINUOUSLY exceeds 1.25 Mkm ^ 2 for 3 years straight now, and is larger than 1.5 Mkm ^ 2 so often for such long times that it is not even newsworthy on a skeptic site.
The authors find that the model they use does well at reproducing the magnitude of storm surges and that the primary contribution to such events in the region are
sea surface
height anomalies from the Pacific.
Trends in near surface winds and geopotential
heights over the high - latitude South Pacific are consistent with a role for atmospheric forcing of the
sea ice and air temperature
anomalies.
In summary, we showed that the spring temperature
anomalies over the WAIS are significantly correlated with
sea ice in the ABS, with temperature
anomalies at Faraday / Vernadsky, with geopotential
height anomalies in the South Pacific, and with SSTs in the southern tropical western Pacific (Table 4).
Top row (a — c): Regressions of the leading detrended Z850 PC timeseries with

They also find that the primary contribution to storm surges in the region are
sea surface
height anomalies from the Pacific, with local wind patterns causing small spatial differences in the
sea surface
height.
The usual
Sea Ice Extent (JAXA daily data plotted here as an
anomaly — usually 2 clicks to «download your attachment») shows the crazy excursions during 2016 (a lot less
Sea Ice Extent due to a very early melt season and a very late freeze season but with the
height of the melt not as big as some expected and leaving a lot of ice in - place at the
height of te melt).
Indeed,
sea level
anomalies measured by Topex / Poseidon were over 20 centimeters in the equatorial Pacific when the phenomenon was at its
height (and as much as 30 centimeters off the coast of Peru).
The first principal component is significantly correlated with the SAM index (the first principal component of
sea - level - pressure or 500 - hPa geopotential heights for 20u S — 90u S), and the second principal component reflects the zonal wave - 3 pattern, which contributes to the Antarctic dipole pattern of sea - ice anomalies in the Ross Sea and Weddell Sea secto
