| Summary: | <!--!introduction!--> Oceanic frontal zone is key region of the oceanic feedback to the atmosphere in the extratropics. The oceanic frontal zone in the wintertime North Pacific exhibits a unique double fronts structure, with a subtropical oceanic frontal zone (STFZ) and a subarctic frontal zone (SAFZ). The feedback of the variability of the two oceanic frontal zones in the wintertime North Pacific on the atmosphere are investigated using daily observational data. The anomalies of the STFZ and SAFZ are both associated with the dipolar SST anomalies with cold (warm) anomalies in the north (south). Following the peak of the STFZ and SAFZ, the dipolar SST anomalies can both maintain almost 30 days. For the STFZ, the anomalous upward surface heat flux in the south of the STFZ indicates the warming effect of the warm SST anomalies on the overlying atmosphere, resulting in the positive anomalies of the near-surface air temperature. The combined effects of the warm anomalies of the near-surface air temperature ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
