The Kuroshio-Oyashio Extension (KOE) is a region of energetic oceanic mesoscale eddies and vigorous air-sea interaction that can influence climate variability over the northwest Pacific and East Asia. General circulation models (GCMs) exhibit considerable differences in their simulated climatology around ...
To investigate the variability in the Chl and its relationship to MLD, we made continuous observations of chlorophyll a fluorescence in the Kuroshio–Oyashio Extension region (Fig. 1) using profiling floats with a fluorescence sensor attached. In the Kuroshio–Oyashio Extension region in the western...
Therefore, multiple increases in the Tr values during MIS 19c were possibly associated with Kuroshio extension during summer to autumn, and such signals were not recognized/ in the winter-spring records of planktonic δ18O. Millennial-scale Kuroshio–Oyashio fluctuations during the interglacial stage ...
Coupled Ocean-Atmosphere Responses to Recent Freshwater Flux Changes over the Kuroshio-Oyashio Extension RegionZhang, L.-P, L.-X. Wu, and J.-X. ZhangJournal of Climate, in pressObservations have indicated a trend of freshwater loss in the global western boundary current extension regions over ...
These findings indicate that the ocean can force the overlying atmosphere in the KOC region. The KOC region is one of the regions of highest eddy kinetic energy in the world’s oceans9,10, due to (1) perturbations of the Kuroshio Extension (KE) (i.e., meanders of the KE)11,12; (2...
By the inspection to the satellite altimetry-derived sea surface height (SSH) dataset of 19932006, it is inferred that the SST variations in the KOC region result from activities of anticyclonic (warm) eddies which are detached from the Kuroshio Extension: the SST anomaly tends to be higher ...
Through analysis of a hindcast integration of an eddy-resolving quasi-global ocean general circulation model, decadal variability in the Kuroshio鈥揙yashio Extension region is investigated, with particular emphasis on that of the subarctic (Oyashio) and the Kuroshio Extension (KE) fronts. The KE ...
Variability in the chlorophyll a concentration (Chl) in relation to fluctuations in the mixed layer (ML) was investigated together with turbidity (Tur) in the Kuroshio-Oyashio Extension region, using profiling floats. A particular focus was the validity of two hypotheses concerning the spring bloom...

In this study, the rectified effect of SSTmeso on local climatological precipitation in the Kuroshio-Oyashio Extension (KOE) region is investigated using the Weather Research and Forecasting (WRF) Model; two runs are performed, one forced by low-resolution SST fields (almost no mesoscale signals)...
