abstract = "{Seasonal and interannual variability of ocean bottom pressure (OBP) in
the Southern Ocean was investigated using Gravity Recovery and
Climate Experiment (GRACE) data and a Pressure Coordinate Ocean
Model (PCOM) based on mass conservation. By comparing OBP,
steric sea level, and sea level, it is found that at high
latitudes the OBP variability dominates the sea level
variability at seasonal-to-decadal time scales. The diagnostic
OBP based on barotropic vorticity equation has a good
correlation with the observations, indicating that wind forcing
plays an important role in the variability of the OBP in the
Southern Ocean. The unique interannual patterns of OBP in the
Southern Ocean are closely associated with El Ni{\~n}o-Southern
Oscillation (ENSO) and Southern Annular Mode (SAM). Regression
analysis indicates that ENSO and SAM influence the OBP through
altering the Ekman transport driven by surface wind. The leading
pattern of OBP from PCOM are very similar to observations.
Sensitive experiments of PCOM show that surface wind forcing
explains the observed OBP variability quite well, confirming the
importance of wind forcing and related oceanic processes. In the
eastern South Pacific, the averaged OBP shows a decrease
(increase) trend before (after) 2011, reflecting the reverse
trend in westerly wind. In the South Indo-Atlantic Ocean, the
averaged OBP has a weak increase trend during
2003{\textendash}2016.}",
