The SSM/I wind data were obtained from the Physical Oceanography Distributed Active Archive Center (http://podaac.jpl.nasa.gov). The NCEP reanalysis was provided by the NOAA/CIRES Climate Diagnostics Center (http://www.cdc.noaa.gov). The satellite merged SSH data were obtained from APDRC in IPRC-SOEST, University of Hawaii (http://apdrc.soest.hawaii.edu). Mentawai coral delta18O data and the DMI reconstruction are provided by N. J. Abram through the NOAA/NCDC Paleoclimatology Program (Data Contribution Series 2009-137).

摘要: The tropical Indian Ocean dipole/zonal mode (IOD) is phase locked with the austral winter and spring seasons. This study describes three types of the IOD in terms of their peak time and duration. In particular, the authors focus on a new type that develops in May-June and matures in July-August, which is distinctively different from the canonical IOD, which may develop later and peak in September-November or persist from June to November. Such "unseasonable" IOD events are only observed since the mid-1970s, a period after which the tropical Indian Ocean has a closer relationship with the Pacific Ocean. The unseasonable IOD is an intrinsic mode of the Indian Ocean and occurs without an ensuing El Nino. A change in winds along the equator is identified as a major forcing. The wind change is in turn related to a weakening Walker circulation in the Indian Ocean sector in austral winter, which is in part forced by the rapid Indian Ocean warming. Thus, although the occurrence of the unseasonable IOD may be partially influenced by oceanic variability, the authors' results suggest an influence from the Indian Ocean warming. This suggestion, however, awaits further investigation using fully coupled climate models.
