In what is an unfavorable signal for this years monsoon in India, United States government weather condition companies have, for the 3rd month running, reiterated the possibility of El Nino conditions developing in late summer season this year.The March update of United States agencies connected to the National Oceanic and Atmospheric Administration (NOAA) on conditions in the Pacific Ocean, launched late Thursday, repeats the model forecasts of the previous two months on the possibility of an El Nino forming around July-August this year.

That the signal for El Nino has actually continued weather models for 3 months strengthens the forecast although experts, consisting of IMD officials, have actually stated that a clearer picture will emerge only by next month (in April), when spring conditions in the Pacific are taken into account.El Nino is an unusual warming of surface area ocean currents in the east and main equatorial Pacific that refers modifications in wind flows, affecting weather condition patterns across numerous areas of the globe.

An El Nino normally causes bad summer season monsoon rains over India, although there have actually been exceptions to this in the past.The latest bulletin stated La Nina conditions had finally dissipated after continuing for three years.

La Nina is the reverse of El Nino, representing a cooling of waters in east and central Pacific.

La Nina has ended and ENSO-neutral conditions are expected to continue through the northern hemisphere spring and early summertime 2023, it said.The models predict a rapid shift to El Nino later on this year.

Nevertheless, while the February projection had actually projected a greater likelihood of El Nino (than neutral conditions) by around July this year, the most recent upgrade shows an El Nino establishing just by August.Usually, an El Nino or La Nina event is followed by a year or more of neutral conditions.

The last time a La Nina transitioned to an El Nino in the exact same fiscal year was in 2009.

While the possible look of an El Nino this year does not bode well for monsoon rains in the country, which have implications for the kharif crop output, there are several other aspects that figure out the quantum of rains during the June-September season, such as conditions in the Indian Ocean (Indian Ocean dipole or IOD), the Eurasian snow cover, intra-seasonal variations etc.India has had excellent monsoon rainfall in the last 4 years, three of which were La Nina years.

In the last few years, bad monsoon rains in 2009, 2014, 2015 and 2018 have actually corresponded with El Nino years.
