| Research Abstract |
Through analysis of the new reanalysis data of the global atmosphere (JRA-25) and numerical modeling, (1) we have postulated a new framework of the atmospheric general circulation with particular emphasis on the role of interaction with midlatitude oceanic frontal zones in the formation of westerly jet and its dominant variability, (2) revealed the characteristics of two anomaly patterns as a dynamical mode that influence of the summertime Bonin High, (3) elucidated the dynamics of the Southern Hemisphere summertime subtropical highs, and (4) assessed the pre-dictability of the tropospherestratosphere coupled variability.
