TL;DR: In this article, a multi-reanalysis ensemble is used to estimate the signal-to-noise ratio (SNR) of the ocean state and to estimate uncertainty levels.
Journal ArticleDOI
Preliminary Numerical Experiments on Oceanic Dispersion of 131I and 137Cs Discharged into the Ocean because of the Fukushima Daiichi Nuclear Power Plant Disaster

TL;DR: In this article, preliminary numerical experiments on Oceanic Dispersion of 131I and 137C Discharged into the Ocean because of the Fukushima Daiichi Nuclear Power Plant Disaster are presented.
Journal ArticleDOI
Pacific decadal oscillation hindcasts relevant to near-term climate prediction
Takashi Mochizuki,Masayoshi Ishii,Masahide Kimoto,Yoshimitsu Chikamoto,Masahiro Watanabe,Toru Nozawa,Takashi T. Sakamoto,Hideo Shiogama,Toshiyuki Awaji,Toshiyuki Awaji,Nozomi Sugiura,Takahiro Toyoda,Sayaka Yasunaka,Hiroaki Tatebe,Masato Mori +14 more
TL;DR: Ensemble hindcasts for the 20th century demonstrate a predictive skill in the upper-ocean temperature over almost a decade, particularly around the Kuroshio-Oyashio extension and subtropical oceanic frontal regions where the PDO signals are observed strongest.
Journal ArticleDOI
Simulated Rapid Warming of Abyssal North Pacific Waters
Shuhei Masuda,Toshiyuki Awaji,Toshiyuki Awaji,Nozomi Sugiura,J. P. Matthews,Takahiro Toyoda,Yoshimi Kawai,Toshimasa Doi,Shinya Kouketsu,Hiromichi Igarashi,Katsuro Katsumata,Hiroshi Uchida,Takeshi Kawano,Masao Fukasawa +13 more
TL;DR: Computer simulations reveal a fast teleconnection between changes in the surface air-sea heat flux off the Adélie Coast of Antarctica and the bottom-water warming in the North Pacific, which can occur within four decades, rather than the centuries that conventional mechanisms have suggested.
Journal ArticleDOI
The Generation of Large-Amplitude Unsteady Lee Waves by Subinertial K1 Tidal Flow: A Possible Vertical Mixing Mechanism in the Kuril Straits
Tomohiro Nakamura,Toshiyuki Awaji,Takaki Hatayama,Kazunori Akitomo,Takatoshi Takizawa,Tokihiro Kono,Yasuhiro Kawasaki,Masao Fukasawa +7 more
TL;DR: In this paper, a two-dimensional non-hydrostatic model was used to investigate the effect of lee waves in the Kuril Straits and their effect on vertical mixing.
