Equatorial East Indian Ocean sea surface temperature: A new predictor for seasonal and annual rainfall

Here we examine the relationship of both the all India annual rainfall (AIAR) and the Indian southwest monsoon rainfall (ISWMR) with global sea ice sea surface temperature of the equatorial (EQ) East Indian Ocean along the grid 5S–5N, 85E–95E. A strong positive correlation (99%) exists between the A...

Zusammenfassung:Here we examine the relationship of both the all India annual rainfall (AIAR) and the Indian southwest monsoon rainfall (ISWMR) with global sea ice sea surface temperature of the equatorial (EQ) East Indian Ocean along the grid 5S–5N, 85E–95E. A strong positive correlation (99%) exists between the April SST (sea surface temperature) in the region EQ–5N, 85E–95E and the AIAR, while a negative correlation (95%) exists between June SST in the region 5S–EQ, 85E–95E and the ISWMR. The SSTs in the grid could be used to predict the AIAR and the ISWMR prior to 8 and 3 months respectively.
