Uncertainty in
future regional sea level rise due to internal climate variability
Aixue Hu and
Clara Deser
Article first
published online: 3 JUN 2013 | DOI: 10.1002/grl.50531
Key Points
•Internal
climate variability can affect the regional sea level
•Regional sea
level rise can significantly differ from the global mean changes
•Ocean
dynamics plays important role on regional sea level rise
6.
Climate-driven
sea level anomalies modulate coastal groundwater dynamics and discharge
Meagan Eagle
Gonneea, Ann E. Mulligan and Matthew A. Charette
Article first
published online: 3 JUN 2013 | DOI: 10.1002/grl.50192
Key Points
•Salinity of
the coastal aquifer mixing zone is dynamic across a 4 year time
series
•Mean sea
level oscillations drive the coastal hydraulic gradient
•Coastal
aquifer geochemistry is sensitive to climate-influenced sea level anomalies
7.
Tidal
dissipation in the early Eocene and implications for ocean mixing
J. A. M. Green
and M. Huber
Article first
published online: 4 JUN 2013 | DOI: 10.1002/grl.50510
Key Points
•The tidal
dissipation during the Eocene was weaker than at present
•The abyssal
Pacific was the main location of tidal dissipation
•The vertical
mixing in the Eocene Pacific was stronger than at present

Rapid ice
melting drives Earth's pole to the east
J. L. Chen1,*,
C. R. Wilson1,2, J. C. Ries1, B. D. Tapley1
Article first
published online: 7 JUN 2013
DOI:
10.1002/grl.50552
Key Points
•First
explained the abrupt departure of the mean pole position in recent years.
•Polar motion
provides constraints to study of ice melting and sea level rise.
•Polar motion
is useful in bridging the gap between GRACE and follow-on missions.

Aragonite
saturation state dynamics in a coastal upwelling zone (pages 1–6)
Katherine E.
Harris, Michael D. DeGrandpre and Burke Hales
Article first
published online: 6 JUN 2013 | DOI: 10.1002/grl.50460
Key Points
•Aragonite
saturation states are calculated from time series pH and pCO2 data
•Seasonal
processes controlling aragonite saturation state are determined
•Current coastal
upwelling zone variability compared to preindustrial range
10. Intraseasonal variations in the surface layer
heat balance of the central equatorial Indian Ocean: The importance of zonal
advection and vertical mixing
M. J. McPhaden
and G. R. Foltz
Article first
published online: 6 JUN 2013 | DOI: 10.1002/grl.50536
Key Points
•Two MJO
events forced an SST decrease that was in part due to reduced heat fluxFor one •MJO
zonal advection contributed substantial cooling
•For other
event lack of barrier layer enabled pronounced entrainment
11. Eddy-induced variability of the meridional
overturning circulation in a model of the North Atlantic
M. D. Thomas
and X. Zhai
Article first
published online: 7 JUN 2013 | DOI: 10.1002/grl.50532
Key Points
•Unpredictable
eddy-induced overturning variability is isolated in 1/10deg model
•Eddies make
up 2/3 of overturning variability in the subtropics and 1/3 outside
•An important
component of eddy driven overturning is at interannual time scales
12. Anthropogenic sulfate aerosol and the southward
shift of tropical precipitation in the late 20th century
Yen-Ting Hwang,
Dargan M. W. Frierson and Sarah M. Kang
Article first
published online: 7 JUN 2013 | DOI: 10.1002/grl.50502
Key Points
•A southward
shift of tropical rain in the 1980s is detected in observations
•Most CMIP3/5
GCMs simulate the shift, although less than observed
•Anthropogenic
sulfate emissions cause most of the southward shift in the GCMs
