According to ERSSTv4, 2017 MAMJ WEP and WNP SST values were the second warmest or warmest on record.
1) indicate that EA MAMJ droughts are associated with warm WNP/WEP SST and stronger Walker circulation anomalies.

Three distinct seasons are recognized in Bangladesh: the premonsoon or summer season (MAMJ), the monsoon/rainy season (JASO), and the postmonsoon or winter season (NDJF) .
In summer (MAMJ), the PCI values showed a moderate precipitation distribution, with the north-west and south to south-east regions showing a highly moderate distribution (Figures 5(d)-5(f)).
Differentiation was observed for MAMJ in all decades except 2000-2011.
