1.  A 4 kyr stalagmite oxygen isotopic record of the past Indian summer monsoon in the Andaman Islands
Amzad H. Laskar, M. G. Yadava, R. Ramesh, V. J. Polyak, Y. Asmerom
DOI: 10.1002/ggge.20203
Keywords: stalagmite; stable isotopes; Indian Summer Monsoon; Roman Warm Period; Medieval Warm Period


Geophysical Research Letters
2.    Second peak in the far eastern Pacific sea surface temperature anomaly following strong El Niño events
WonMoo Kim, Wenju Cai
DOI: 10.1002/grl.50697
Key Points
    There is a second peak after strong El Nino
    The second peak is generated by anomalous ocean circulation
    There exists a pause between the peaks due to atmosphere-ocean interaction

3.    Dependence of abrupt Atlantic meridional ocean circulation changes on climate background states
Xun Gong, Gregor Knorr, Gerrit Lohmann and Xu Zhang
DOI: 10.1002/grl.50701
Key Points
    The Recovery characteristics of a suppressed AMOC depend on the climate state
    Advected tropical water governs overshoot in Labrador Sea deep-water formation

Journal of Geophysical Research: Atmospheres
4.    Transient simulation of orbital-scale precipitation variation in Monsoonal East Asia and Arid Central Asia during the Last 150ka
Xinzhou Li, Xiaodong Liu, Linjing Qiu, Zhisheng An and Zhi-Yong Yin
DOI: 10.1002/jgrd.50611
Key Points
    The past 150ka transient simulation is conducted with the CCSM3
    There is an in-phase variation of annual precipitation between E Asia and C Asia
    Precession modulates both Asian summer monsoon and winter westerly circulation

5.    El Niño Southern Oscillation in an ensemble ocean reanalysis and coupled climate models
Chunxue Yang and Benjamin S. Giese
DOI: 10.1002/jgrc.20284
Key Points
    The long-term change of ENSO in ensemble ocean reanalysis and climate models.
    ENSO has prominent decadal variability in ensemble reanalysis.
    Most of models in CMIP5 have realistic representation of the strength of ENSO.

6.    Statistical constraints on El Niño Southern Oscillation reconstructions using individual foraminifera: a sensitivity analysis
Kaustubh Thirumalai, Judson W. Partin, Charles S. Jackson and Terrence M. Quinn
DOI: 10.1002/palo.20037
Key Points
    ENSO reconstructions from individual forams have multiple sources of uncertainty
    IFA standard deviation is more precise and accurate than IFA range
    The seasonal cycle can play an influential role in the IFA-signal

7.    Agulhas salt-leakage oscillations during abrupt climate changes of the Late Pleistocene
Gianluca Marino, Rainer Zahn, Martin Ziegler, Conor Purcell, Gregor Knorr, Ian R. Hall, Patrizia Ziveri and Henry Elderfield
DOI: 10.1002/palo.20038
Key Points
    Millennial-scale variability of the Agulhas Leakage
    Connection between Agulhas Leakage and bipolar seesaw
    Relationship between Agulhas Leakage and abrupt climate change

8.    A volcanically triggered regime shift in the subpolar North Atlantic Ocean as a possible origin of the Little Ice Age
C. F. Schleussner and G. Feulner
DOI:10.5194/cp-9-1321-2013

9.    Millennial-scale variability of marine productivity and terrigenous matter supply in the western Bering Sea over the past 180 kyr

M.-A. Sicre, G. Siani, D. Genty, N. Kallel, and L. Essallami
DOI:10.5194/cp-9-1375-2013
