Enso Neutral Conditions Prevails July 2018 – ONI Index is Just +0.1C For MJJ 2018 – East Pacific Is Colder Than Normal

Enso Status on 11th August 2018

Enso Neutral Conditions Prevails July 2018

How ONI is determined:

The ONI is based on SST departures from average in the Niño 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 Niño 3.4 region. Departures are based on a set of further improved homogeneous historical SST analyses (Extended Reconstructed SST – ERSST.v5). Explanation about ERSST.v5 is given here.

The SST reconstruction methodology is described in Huang et al., 2015, J. Climate, vol. 28, 911-930.
CPC uses current Climatology based on 1986-2015 which has been changed late last year from base years 1981-2010. Explanation about Climatology base years change is given here.

NOAA Operational Definitions for El Niño and La Niña, El Niño: characterized by a positive ONI greater than or equal to +0.5ºC. La Niña: characterized by a negative ONI less than or equal to -0.5ºC. By historical standards, to be classified as a full-fledged El Niño or La Niña episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.

CPC considers El Niño or La Niña conditions to occur when the monthly Niño3.4 OISST departures meet or exceed +/- 0.5ºC along with consistent atmospheric features. These anomalies must also be forecast to persist for 3 consecutive months.

Last five ONI Index are JFM 2018 -0.8ºC, FMA 2018 -0.6ºC, MAM 2018 -0.4ºC, AMJ 2018 -0.1ºC and MJJ 2018 +0.1ºC. Latest Nino 3.4 SST is +0.17ºC and the calculated ONI MJJ 2018 is +0.1ºC, though positive but in neutral zone. Hence ENSO neutral conditions continues to exist.

La Nina event 2017-18 had officially ended at the end of April 2018 (FMA 2018). ENSO neutral conditions exists since then.

Southern Oscillation Index

 

As per BOM, Australia:

The 30-day Southern Oscillation Index (SOI) to 29 July was +2.2, and the 90-day SOI was −0.4. The SOI is +1.9 on 2nd August 2018 and has been within the neutral range since late April.

Sustained negative values of the SOI below −7 typically indicate El Niño while sustained positive values above +7 typically indicate La Niña. Values between +7 and −7 generally indicate neutral conditions.

 

 

Recent (preliminary) Southern Oscillation Index values as per The Long Paddock – Queensland Government.

30 Days average SOI was +1.79 at the end of July 2018 and was +1.18 on 1st August 2018 as per The Long Paddock – Queensland Government and 90 Days average SOI was -0.68.

Summary by: Climate Prediction Center / NCEP  Dated 6th August 2018

ENSO Alert System Status: El Niño Watch

ENSO-neutral conditions are present.*
Equatorial sea surface temperatures (SSTs) are near-to-above average across most of the Pacific Ocean.
ENSO-neutral is favored through Northern Hemisphere summer 2018, with the chance for El Niño increasing to about 65% during fall, and to about 70% during winter 2018-19.

* Note: These statements are updated once a month (2nd Thursday of each month) in association
with the ENSO Diagnostics Discussion, which can be found by clicking here.
