Intense Monsoon in India

main reason for plentiful rainfall India has received this year is because of what wear bureaus like Skymet and IMD have stated - El Niño effect. El Niño as explained by US National Oceanic and Atmospheric ministration is a large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across central and east-central Equatorial Pacific.

Skymet h initially predicted in April that a 'weak' El Niño would persist, resulting monsoon to be below rmal at 93% LPA. But as months progressed, amidst an ongoing El Niño, monsoon gained speed and reaching its peak in July-August period and steily rising at end of September. While re were acute droughts Maharashtra, Gujarat, Karnataka, Andhra Presh, Telangana and Tamil Nu in summer- especially in May 2019, a strong El-Ni saw a stey rise in monsoon in consecutive months.
