Abstract
This study investigates possible mechanisms under what circumstances the North Pacific Victoria mode (VM) is more likely to trigger the eastern Pacific (EP) or central Pacific (CP) El Niño event. Results indicate that while positive VM events can provide the initiates to the onset of El Niño events via forcing initial warming of sea surface temperature (SST) anomalies to occur in the central equatorial Pacific from springtime to summer, the changes in background conditions of the equatorial Pacific at the same period also are crucial contributors to the development of VM-EP or VM-CP El Niño events. That is when we predict the spatial patterns of El Niño events in advance, the extratropical variabilities and changes in the background conditions of the tropical Pacific should be both taken into consideration, rather than considered individually. For VM-EP El Niño cases, the significantly negative SST anomalies from the eastern tropical Pacific experience a fast transition into positive. These SST anomalies are usually accompanied by sign reversal of zonal wind anomalies near the dateline, finally together supplying favorable conditions for the eastward propagation of the initial warming anomalous SST generated by VM event. For VM-CP El Niño cases, there are also negative SST anomalies in the eastern equatorial Pacific, however, they can linger much longer than the former case and transit relatively slow to positive SST anomalies, which together along with the muted anomalous westerlies around the dateline suppress the eastward propagation of the warm SST anomalies generated by VM events. The changes of subsurface water are further in accordant to the results in the sea surface. Two simple statistical models for EP and CP El Niño prediction are derived depending on evolutionary features in both north and tropical Pacific, showing high prediction skills by 2-season in advance. These findings may provide useful insights for understanding the predictability of El Niño diversity.
