Oceanic parameters like La Nina, IOD, and MJO are approaching a crucial phase. These indices play a decisive role in the overall performance of the southwest monsoon. El Nino/La Nina will soon cross the spring barrier and the Indian Ocean Dipole projection will become more reliable in May.
La Nina event is continuing, with no acute signs of softening. Sea Surface Temperatures (SSTs) remain below average in the central-eastern equatorial Pacific Ocean.
Sea Surface Temperatures (SSTs) remain below average in the central-eastern equatorial Pacific Ocean. In accordance with prevailing oceanic and atmospheric conditions, weak La Nina continues to prevail.
ENSO pattern and IOD plot are very crucial for the upcoming Indian southwest monsoon season. Degree of difficulty increases for the predictions with evolving 'spring barrier'.
