Abstract. The sixth version of the Model for Interdisciplinary Research on Climate (MIROC), called MIROC6, was cooperatively developed by a Japanese modeling community. In present paper, simulated mean climate, internal climate variability, and sensitivity in MIROC6 are evaluated briefly summarized comparison with previous our model (MIROC5) observations. results show that overall reproducibility variability is better than MIROC5. tropical systems (e.g., summertime precipitation western...

To elucidate the distribution and circulation dynamics of Campylobacter Salmonella in Japanese chicken broiler flocks.A 2-year investigation was conducted 25 flocks at nine farms Japan from 2013 to 2014. tested positive 11 (44·0%) 24 (96·0%) respectively. One hundred ninety-five 184 isolates were characterized into 12 (including two novel genotypes) three MLST genotypes. Only isolation between caecal environmental samples significantly correlated. Further, one litter sample for before new...
Using a two‐way nested‐grid ocean general circulation model driven by repeat annual cycle forcing, the Kuroshio path variation is examined varying strength of wind forcing. For climatological or 10% weaker both large‐meander (LM) and non‐large‐meander (NLM) paths alternately appear, with each type continuing for few years to decade. This timescale transition processes are generally consistent observations. LM path, main balance in depth‐integrated vorticity equation upper shown be between...
To investigate the role of wind stress field in determining stable paths Kuroshio south Japan, we have executed numerical experiments with a two‐layer, wind‐driven ocean model, changing zonal and meridional distributions. Four types path (two straight two meandering paths) been found, their appearance has classified into three categories. In category I, coexist (multiple equilibrium); only (straight) appears II (III). A tends to appear when Sverdrup transport along southern coast Japan...
Abstract Even in coastal oceans where tidal currents are predominant, long-term mean of great interest since they responsible for the transport materials over long timescales. Tides could significantly affect long, narrow straits due to tide-topography interaction, but it is yet unclear how and what extent tides control throughflows. Here, we focus on throughflow Seto Inland Sea, Japan, which has enormous impacts marine environment while its characteristics, even flow direction, not well...
Abstract In this study, we developed a new version of the future ocean regional projection dataset in North Pacific (FORP-NP10) by performing an ensemble historical and multi-scenario simulations from 1960 to 2100 using high-resolution downscaling model system driven surface forcings based on atmospheric data Coupled Model Intercomparison Project (Phase 5). This is characterized inclusion simple biogeochemical processes within multi-case (four forcing cases) multi-future scenarios...
Abstract To clarify characteristics and mechanisms of mesoscale variability in the deep ocean, we conducted a two-dimensional observation with 3 × grid mooring array around site R (30°N, 147°E) during 2014–16. We analyze obtained velocity data together past northwest Pacific basin outputs an ocean general circulation model (OGCM). In our observations, zonal meridional velocities at depth 4000 m was prominent periods 174 58 days, respectively. The days propagated to west-southwest,...
Abstract Atmospheric responses and feedback to meridional ocean heat transport (OHT) have been investigated using a global climate model that is interactively connected with high-resolution regional embedded in the western North Pacific. Compared without model, net supply into Kuroshio–Oyashio Extension (KOE) region increased as result of increase mean northward by boundary currents mesoscale eddies. Resultant sea surface temperature (SST) rise sharpens SST gradient reinforces cross-frontal...
