Monsoon cheers as cooler pacific signals El Nino end


The ‘Godzilla’ El Nino, one of the strongest in the history and  seemed to be the major reason for the poor rainfall in the past 2 years has finally come to an end, the Australian Bureau of Meteorology announced.

El Nino is an unusual warming of the sea surface in equatorial Pacific Ocean, off the coast of Peru and Ecuador in South America, is known to influence weather events across the world, also the India monsoon rainfall. This current spell being the one of the longest and the strongest ever, thus, earned the name of ‘Godzilla’.

The  Australian bureau said on Tuesday, “sea surface temperature round the tropical Pacific have cooled down to neutral levels over the past fortnight, supported by much cooler-than-average waters beneath the surface.”

“Little chances of sea surface temperature returning to El Nino levels, in which case mid-May will mark the end of El Nino.”

Other weather agencies have not yet announced the end of El Nino though they have been predicting that it will be over by the end of summer. The Climate Prediction Centre of National Oceanic and Atmospheric Administration (NOAA) of United States, in its latest bulletin on Monday, said that “El Nino is weakening”.

Beneficial for Agriculture

Private weather agency Skymet said in a Wednesday statement that it expected all of the monsoon months, except June, to record rains well above what’s usual and would translate into gains for Indian agriculture.

According to the IMD’s latest update, the monsoon is likely to set in on June 7 over Kerala. This was partly due to a depression in the Bay of Bengal that morphed into cyclone Roanu and brought heavy rains to Andhra Pradesh, Tamil Nadu and killed at least 20 in Bangladesh.

The monsoon-rain-bearing systems were yet to gain enough force to coast over India and though the El Nino was gone, it would take some time for its effect to spill over into the atmosphere and aid the monsoon, said Rajeevan. These developments would be factored into IMD’s update — next month — to the April monsoon forecast, that had forecast monsoon rains to be 106% of the 89 cm historical average.
