<p>Oceanic fronts impact tropospheric atmosphere and facilitate the maintenance and development of storm tracks. By using the high-resolution satellite-observed sea surface temperature (SST) data and the generalized equilibrium feedback analysis method, this study aimed to evaluate the responses of North Pacific storm track (NPST) activity to Kuroshio Extension Front (KEF) and Oyashio Extension Front (OEF) intensity and position changes during the cold season. Results showed that the responses of the NPST to the KEF and OEF position changes were most significant in spring (March to May), presenting similar spatial distributions but with opposite signs. Specifically, the response of the NPST to the KEF (OEF) position change showed a significant negative (positive) anomaly in the western and central North Pacific. Furthermore, corresponding to the northward shift of the KEF, the significant SST cooled in the north of its climatological position, whereas a significant SST warming from east of Japan to 165°E corresponded to the northward shift of the OEF. The SST variations affected the turbulent heat flux anomaly, resulting in localized changes in low-level air temperature. This can cause negative and positive anomalies in the baroclinicity and baroclinic energy conversion in the lower atmosphere over the east of Japan. Although a significant positive correlation between the position changes of the KEF and OEF exists, the response signs of the NPST to the changes in these two oceanic fronts are opposite. These results emphasize the sensitivity of the storm track response to the location of the oceanic front forcing.</p>
