1. Response of extratropical cyclone activity to the Kuroshio large meander in northern winter
Masamitsu Hayasaki, Ryuichi Kawamura, Masato Mori and Masahiro Watanabe
Accepted manuscript online: 10 MAY 2013 DOI: 10.1002/grl.50546
・High-resolution air-sea coupled model reproduces a large meander of the Kuroshio
・Its meander leads to decreased latent heat flux and weakened baroclinicity
・Primary path of cyclones is very sensitive to the large meander of Kuroshio
2. Consistency of 20th century sea level pressure trends as simulated by a coupled and uncoupled GCM
Ioana Colfescu, Edwin K. Schneider and Hua Chen
Accepted manuscript online: 9 MAY 2013 DOI: 10.1002/grl.50545
・SLP trends are analyzed in externally forced coupled and uncoupled GCMs
・SLP trends are attributed to external forcing and internal mechanisms
・Forced SLP trends in coupled and uncoupled simulations are similar
3. Recent Increase in High Tropical Cyclone Heat Potential Area in the Western North Pacific Ocean
Iam-Fei Pun, I.-I. Lin and Min-Hui Lo
Accepted manuscript online: 9 MAY 2013 DOI: 10.1002/grl.50548
・Ocean conditions in the MDR are becoming even more favorable for typhoons
・Averaged D26 and TCHP over MDR have increased by 10% as compared to the 90's
・There is a 13% increase in high TCHP (>= 110kj/cm2) area coverage
4. Overturning circulation driven by breaking internal waves in the deep ocean
Maxim Nikurashin and Raffaele Ferrari
Accepted manuscript online: 9 MAY 2013 DOI: 10.1002/grl.50542
・Internal wave driven mixing sustains 20-30Sv of water-mass transformation
・Internal wave driven mixing impacts primarily the abyssal cell (AABW) of the MOC

5. Strengthening of ocean heat uptake efficiency associated with the recent climate hiatus
Masahiro Watanabe, Youichi Kamae, Masakazu Yoshimori, Akira Oka, Makiko Sato, Masayoshi Ishii, Takashi Mochizuki and Masahide Kimoto
Accepted manuscript online: 8 MAY 2013 DOI: 10.1002/grl.50541
・Global-mean SAT trend for 2001-2010 is barely represented by GCM ensembles
・Ocean heat uptake efficiency is weakening in GCMs and strengthening in nature
・Weakening of uptake efficiency is inevitable response of forced climate system

David E. Siskind, Michael H. Stevens, Mark E. Hervig and Cora E. Randall
Accepted manuscript online: 8 MAY 2013 DOI: 10.1002/grl.50540

7. Contrail ice particles in aircraft wakes and their climatic importance
Ulrich Schumann, Philipp Jeßberger and Christiane Voigt
Accepted manuscript online: 8 MAY 2013 DOI: 10.1002/grl.50539
・Gaseous and ice particle concentrations were measured within aircraft wakes

8. Intraseasonal Variations in the Surface Layer Heat Balance of the Central Equatorial Indian Ocean: The Importance of Horizontal Advection and Vertical Mixing
M. J. McPhaden and G. R. Foltz
Accepted manuscript online: 6 MAY 2013 DOI: 10.1002/grl.50536
・Two MJO events forced an SST decrease that was in part due to reduced heat flux
・For one MJO zonal advection contributed substantial cooling
・For other event lack of barrier layer enabled pronounced entrainment
9. Oceanic hindcast simulations at high resolution suggest that the Atlantic MOC is bistable
J. Deshayes, A.-M. Tréguier, B. Barnier, A. Lecointre, J. Le Sommer, J.-M. Molines, T. Penduff, R. Bourdallé-Badie taffilmark, Y. Drillet, G. Garric, R. Benshila, G. Madec, A. Biastoch, C. Böning, M. Scheinert, A. C. Coward and J. J.-M. Hirschi
Accepted manuscript online: 6 MAY 2013 DOI: 10.1002/grl.50534
・Simulated AMOC freshwater transport in South Atlantic depends on resolution
・AMOC in high resolution hindcasts exports freshwater southward, on average
・AMOC freshwater export has large variability at intra-seasonal timescale

1. Remote impacts of the 18.6-year period modulation of localized tidal mixing in the North Pacific
S. Osafune and I. Yasuda
Accepted manuscript online: 9 MAY 2013 DOI: 10.1002/jgrc.20230
・The 18.6-year periods tidal cycle could influence large-scale SST.
・Changes in mid-depth density could link tidal mixing to decadal climate.
