Based on earlier more than 100 years weather Data for Indian Summer Monsoon, The Average Rainfall in an El Nino years is 94% of LPA while in La Nina Years it has been 106 % of LPA. El Nino or La Nina may affect the Monsoon differently for different Regions of India and the same is being researched for some concrete co-relations.<\/p>\n <\/p>\n \u0a85\u0ab6\u0acb\u0a95 \u0aaa\u0a9f\u0ac7\u0ab2\u00a0\u0aa8\u0ac1\u0a82 \u0aa4\u0abe\u0ab0\u0aa3 \u0a85\u0aa8\u0ac7 \u0ab5\u0abf\u0ab6\u0acd\u0ab2\u0ac7\u0ab7\u0aa3 : NOAA \u0aae\u0abe\u0aaa\u0aa6\u0a82\u0aa1 \u0aae\u0ac1\u0a9c\u0aac \u0aae\u0abe\u0ab0\u0acd\u0a9a \u0a86\u0a96\u0ab0 \u0aae\u0abe\u0a82 \u0ab5\u0abf\u0aa7\u0abf\u0ab5\u0aa4 \u2018\u0a8f\u0ab2 \u0aa8\u0abf\u0aa8\u0acb\u2019 \u0aa1\u0abf\u0a95\u0acd\u0ab2\u0ac7\u0ab0 \u0aa5\u0aaf\u0ac7\u0ab2 \u0a95\u0abe\u0ab0\u0aa3 \u0a95\u0ac7 \u0ab8\u0ab3\u0a82\u0a97 5 \u0a85\u0a82\u0ab6\u0aa4\u0a83 \u0aa2\u0abe\u0a82\u0a95\u0ac7\u0ab2 \u0aa4\u0acd\u0ab0\u0ac0-\u0aae\u0abe\u0ab8\u0abf\u0a95 \u0ab8\u0ac0\u0a9d\u0aa8 \u0aa8\u0ac1\u0a82 ONI \u0a88\u0aa8\u0acd\u0aa1\u0ac7\u0a95\u0acd\u0ab8 +0.5\u00baC \u0a85\u0aa5\u0ab5\u0abe \u0ab5\u0aa7\u0ac1 \u0ab0\u0ab9\u0ac7\u0ab2 \u0a9b\u0ac7. \u0aa8\u0aac\u0ab3\u0acb \u2018\u0a8f\u0ab2 \u0aa8\u0abf\u0aa8\u0acb\u2019 \u0a98\u0aa3\u0abe \u0aae\u0ab9\u0abf\u0aa8\u0abe \u0a93 \u0aa5\u0aaf\u0abe \u0a9a\u0abe\u0ab2\u0ac1 \u0a9b\u0ac7 \u0a9c\u0ac7\u0aae\u0abe\u0a82 \u0a9c\u0ac1\u0ab2\u0abe\u0a88 2019 \u0aae\u0abe\u0a82 \u0aa8\u0ab5\u0aae\u0ac0 3-\u0aae\u0abe\u0ab8\u0abf\u0a95 \u0ab8\u0ac0\u0a9d\u0aa8 \u0a8f\u0a9f\u0ab2\u0ac7 \u0a95\u0ac7 MJJ 2019 \u0aa8\u0ac1\u0a82 ONI \u0a88\u0aa8\u0acd\u0aa1\u0ac7\u0a95\u0acd\u0ab8 +0.5\u00baC \u0ab0\u0ab9\u0ac7\u0ab2 \u0a9b\u0ac7. \u0a9b\u0ac7\u0ab2\u0acd\u0ab2\u0abe \u0aa4\u0acd\u0ab0\u0aa3 \u0aae\u0ab9\u0abf\u0aa8\u0abe \u0aa8\u0ac1\u0a82 Nino3.4 SST \u0a8d\u0aa8\u0acb\u0aae\u0ab2\u0ac0 \u0a9c\u0ac2\u0aa8 +0.54\u00baC \u0a85\u0aa8\u0ac7 \u0a9c\u0ac1\u0ab2\u0abe\u0a88 +0.44\u00baC \u0a9b\u0ac7. \u0a9c\u0acb \u0a93\u0a97\u0ab8\u0acd\u0a9f 2019 \u0aa8\u0ac1\u0a82 Nino3.4 SST \u0a8d\u0aa8\u0acb\u0aae\u0ab2\u0ac0 +0.39\u00baC \u0aa5\u0ac0 \u0aa8\u0ac0\u0a9a\u0ac1\u0a82 \u0ab0\u0ab9\u0ac7 \u0aa4\u0acb JJA 2019 \u0aa8\u0ac1\u0a82 ONI +0.5\u00baC \u0aa5\u0ac0 \u0aa8\u0ac0\u0a9a\u0ac1\u0a82 \u0ab0\u0ab9\u0ac7 \u0a8f\u0a9f\u0ab2\u0ac7 \u2018\u0a8f\u0ab2 \u0aa8\u0abf\u0aa8\u0acb\u2019 \u0a96\u0aa4\u0aae \u0aa5\u0abe\u0aaf \u0a85\u0aa8\u0ac7 \u0a9c\u0acb Nino3.4 SST \u0a8d\u0aa8\u0acb\u0aae\u0ab2\u0ac0 +0.39\u00baC \u0a85\u0aa5\u0ab5\u0abe \u0aa4\u0ac7\u0aa5\u0ac0 \u0ab5\u0aa7\u0ac1 \u0ab0\u0ab9\u0ac7 \u0aa4\u0acb \u2018\u0a8f\u0ab2 \u0aa8\u0abf\u0aa8\u0acb\u2019 \u0a9a\u0abe\u0ab2\u0ac1 \u0ab0\u0ab9\u0ac7. \u0ab9\u0abe\u0ab2 \u0aa8\u0ac0 \u0aaa\u0ab0\u0abf\u0ab8\u0acd\u0aa5\u0abf\u0aa4\u0abf \u0aae\u0ac1\u0a9c\u0aac \u2018\u0a8f\u0ab2 \u0aa8\u0abf\u0aa8\u0acb\u2019 \u0a96\u0aa4\u0aae \u0aa5\u0ab5\u0abe \u0aa8\u0ac0 \u0ab6\u0a95\u0acd\u0aaf\u0aa4\u0abe \u0ab5\u0aa7\u0ac1 \u0a9b\u0ac7. The ONI is based on SST departures from average in the Ni\u00f1o 3.4 region, and is a principal measure for monitoring, assessing, and predicting ENSO. Defined as the three-month running-mean SST departures in the Ni\u00f1o 3.4 region. Departures are based on a set of further improved homogeneous historical SST analyses (Extended Reconstructed SST \u2013 ERSST.v5). Explanation about ERSST.v5 is given\u00a0here.<\/a><\/p>\n NOAA Operational Definitions for El Ni\u00f1o and La Ni\u00f1a, El Ni\u00f1o: characterized by a positive ONI greater than or equal to +0.5\u00baC. La Ni\u00f1a: characterized by a negative ONI less than or equal to -0.5\u00baC. By historical standards, to be classified as a full-fledged El Ni\u00f1o or La Ni\u00f1a episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.<\/p>\n CPC considers El Ni\u00f1o or La Ni\u00f1a conditions to occur when the monthly Ni\u00f1o3.4 OISST departures meet or exceed +\/- 0.5\u00baC along with consistent atmospheric features.

\nUsing NOAA Criteria, a full-fledged El Nino event started at the end of March 2019 having fulfilled the five consecutive overlapping\u00a0<\/strong>3-monthly seasons with ONI greater than or equal to\u00a0<\/strong>+0.5\u00baC. El Nino has continued for many months, July 2019 being the ninth 3-monthly season with MJJ 2019 at\u00a0<\/strong>+0.5\u00baC. The last two Nino3.4 SST anomaly for June<\/strong>\u00a0is\u00a0<\/strong>+0.54\u00baC and July is\u00a0<\/strong>+0.44\u00baC. If the Nino3.4 SST anomaly of August manages to go below 0.39<\/strong>\u00baC, the JJA ONI Index would be less<\/strong>\u00a0than\u00a0<\/strong>+0.5\u00baC, and thereby El Nino could transition into ENSO neutral conditions at the end of August 2019. However, if August\u00a0<\/strong>Nino3.4 SST anomaly manages to remain at or above\u00a0<\/strong>0.39<\/strong>\u00baC, a weak El Nino will continue. The chances of El Nino ending at end of August 2019 is high.<\/strong>

\nEl Ni\u00f1o is present.*
\n<\/strong>
\nEquatorial sea surface temperatures (SSTs) are above average across most of the Pacific Ocean. The pattern of anomalous convection and winds are generally consistent with El Ni\u00f1o. A transition from El Ni\u00f1o to ENSO-neutral is expected in the next month or two, with ENSO-neutral most likely to continue through the Northern Hemisphere fall and winter.*<\/p>\n
