| Zusammenfassung |
| An index of El Niño Southern Oscillation (ENSO) in the Pacific during
pre monsoon season is shown to account for a significant part of the
variability of coastal Sea Surface Temperature (SST) anomalies measured a
few months later within the wind driven southwest coast of India coastal
upwelling region 7° N–14° N. This teleconnection is thought to
result from an atmospheric bridge between the Pacific and north Indian
Oceans, leading to warm (cold) ENSO events being associated with relaxation
(intensification) of the Indian trade winds and of the wind-induced coastal
upwelling. This ENSO related modulation of the wind-driven coastal upwelling
appears to contribute to the connection observed at the basin-scale between
ENSO and SST in the Arabian Sea. The ability to use this teleconnection to
give warning of large changes in the southwest coast of India coastal
upwelling few months in advance is successfully tested using data from 1998
and 1999 ENSO events. |
