1. The influence of high-resolution wind stress field on the power input to near-inertial motions in the ocean
Antonija Rimac, Jin-Song von Storch, Carsten Eden and Helmuth Haak
Accepted manuscript online: 9 SEP 2013 06:22AM EST | DOI: 10.1002/grl.50929

2. The role of synoptic eddies in the tropospheric response to stratospheric variability
Daniela I.V. Domeisen, Lantao Sun and Gang Chen
Accepted manuscript online: 9 SEP 2013 02:08PM EST | DOI: 10.1002/grl.50943
Key Points
Planetary-scale waves are crucial for stratosphere - troposphere coupling.
A synoptic - eddy feedback is needed to get the observed response.
The annular mode response is different for planetary- and synoptic-scale waves.

Robin Chadwick and Peter Good
Accepted manuscript online: 9 SEP 2013 03:48PM EST | DOI: 10.1002/grl.50932
Key Points
There are large non-linearities in tropical rainfall pattern change
This has implications for the use of pattern-scaling
The non-linearities are due to the interaction of different processes

Sloan Coats, Jason E. Smerdon, Benjamin I. Cook and Richard Seager
Accepted manuscript online: 9 SEP 2013 09:06PM EST | DOI: 10.1002/grl.50938
Key Points
The ENSO-North American hydroclimate teleconnection is non-stationary in models
Teleconnection non-stationarity is linked to the strength of and changes in ENSO
The assumption of teleconnection stationarity is potentially unwarranted

Accepted manuscript online: 11 SEP 2013 10:09AM EST | DOI: 10.1002/grl.50930
Key Points

T. Cyronak, I. R. Santos and B. D. Eyre
Accepted manuscript online: 11 SEP 2013 04:14PM EST | DOI: 10.1002/grl.50948
Key Points
Advection and elevated CO2 act synergistically to increase CaCO3 dissolution
CaCO3 sediment dissolution under OA is important on an ecosystem scale
Other drivers of CaCO3 sediment dissolution need to be elucidated

Xing Yuan and Eric F. Wood
Accepted manuscript online: 12 SEP 2013 07:50AM EST | DOI: 10.1002/grl.50949
Key Points
Less than 30% of the global drought onsets can be detected by climate models
Missed drought events are associated with weak ENSO signal
Reliability is very important for a skillful probabilistic drought forecast

13. Extratropical forcing of El Niño/Southern Oscillation asymmetry
Bruce T. Anderson, Jason C. Furtado, Kim M. Cobb and Emanuele DiLorenzo
Accepted manuscript online: 12 SEP 2013 10:52AM EST | DOI: 10.1002/grl.50951
Key Points
Extratropical SLP changes impact the longitudinal structure of ENSO events
These impacts are found in observations and coupled-climate model simulations
SLP-induced ENSO asymmetries result in appreciable teleconnection differences

14. Contribution of the pacific decadal oscillation to global mean sea level trends
B.D. Hamlington, R.R. Leben, M.W. Strassburg, R.S. Nerem and K.-Y. Kim

Accepted manuscript online: 9 SEP 2013 09:20PM EST | DOI: 10.1002/palo.20059
Key Points
Observational uncertainties in coral isotope measurements are manageable
Linear SST/SSS to delta 18O conversions yield inaccurate ENSO amplitudes
Climate/delta 18O conversions can be improved by including seasonal influences

Andreas Mackensen
Accepted manuscript online: 9 SEP 2013 09:35PM EST | DOI: 10.1002/palo.20058
Key Points
Strong 13C-Suess effect lowers δ13C of Arctic surface waters
Reduced stadial ABW δ13C suggested - due to diminished brine formation
Stadial benthic δ13C spikes in Nordic seas may reflect less Arctic brine
