. Many studies have reported the SST trend of the East China Sea (e.g., Belkin 2009 ; Tang et al. 2009 ; Wu et al. 2012 ; Bao and Ren 2014 ). Nevertheless, studies examining the mechanism of the SST rise in the East China Sea are limited. Zhang et al. (2010) performed a heat budget analysis using a reanalysis product from 1958 to 2010 and demonstrated qualitatively that the warming around the Kuroshio corresponded to an increase in the anomalous ocean advection and damping by surface heat flux

clearly illustrate a nonnegligible influence of biological heating on regional atmospheric processes. The positive standard deviations to the south and east of the Japan Islands indicate that SLP fluctuations intensified in the blue case. Moreover, in the right panel of Fig. 11 , the positive difference is remarkable in the high-pass (<7 days) filtered poleward eddy heat flux, integrated over the lower atmosphere (<850 hPa). A 7-day boxcar filter was used to obtain subweekly-scale properties required

studies, because of their rather coarse horizontal resolution. Tanimoto et al. (2003) and Taguchi et al. (2009 , 2012 ) have found that, unlike in most of the North Pacific basin where surface heat flux anomalies due to changes in near-surface wind, air temperature, and humidity force SST anomalies, warm (cold) SST anomalies along the SAFZ tend to enhance (reduce) heat release into the atmosphere, which can be regarded as thermodynamic forcing by the SAFZ variability on the overlying atmosphere

response over the Kuroshio and Oyashio Extensions (KOE) using a regional atmospheric model. They suggested that the storm-track response is different between winter and spring. In spring, the surface heat flux gradient is prominent over the SST front, resulting in enhanced storm-track activity, although in winter, the cold and dry air advection associated with the Asian winter monsoon induces large heat fluxes on both the cold and warm sides of the SST front, resulting in a weaker atmospheric response

Japanese islands. This classification is strongly linked with El Niño–Southern Oscillation (ENSO; Wang and Chan 2002 ). The effect of global warming on TC tracks in the western North Pacific has been examined mostly by simulation with a general circulation model (GCM). Because TC tracks are attributable to steering flow, global warming may affect them through its effect on background flow. Though beta drift is typically secondary in environments where the steering flow is stronger than 5 m s −1

1. Introduction The midlatitude western boundary currents, which flow poleward along the western flank of each of the ocean basins, transport an enormous amount of heat from the tropics, releasing it into the midlatitude atmosphere in the form of turbulent sensible heat flux (SHF) and latent heat flux (LHF) while maintaining relatively warm sea surface temperature (SST) along their axes. The midlatitude oceanic frontal zones, which are characterized by steep gradients in SST along the poleward
