10 May 2014 The Southern Oscillation Index from BOM has been around for a long time. It is a commonly used ENSO index. It is noisy and, at times, does not 2 Oct 2019 Earlier in the week the Bureau of Meteorology (BOM) reported that the In the Pacific Ocean, the El Nio-Southern Oscillation (ENSO) remains neutral. although the Southern Oscillation Index (SOI) is negative due to very Tel: +61 3 9669 4217.

The Southern Oscillation Index (SOI) is the difference in barometric pressure at sea level between Tahiti and Darwin. Annual SOI and Australian rainfall data, for the years 1900-2001, are given. Prior to 2000, there are very few differences that exceed 0.3 hPa between the CRU values and either the BoM or CPC values. However the two largest differences in the comparison do occur for Darwin: Feb 1883, the CRU value is 3.6 hPa higher than BoM; Jul 1979, the CRU value matches BoM but is 3.5 hPa higher than CPC. The Southern Oscillation Index (SOI) is calculated from the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin. There are a few different methods of how to calculate the SOI. The method used by the Australian Bureau of Meteorology is the Troup SOI which is the standardised anomaly of the Mean Sea Level Southern Oscillation Index - 30 day Average Courtesy: BOM Measures the relative surface pressure difference between Darwin Australia and Tahiti. Consistently negative values indicate El Nino, positive values La Nina. Short negative spikes are associated with the active phase of the MJO.

Southern Oscillation Index (SOI) The SOI is defined as the normalized pressure difference between Tahiti and Darwin. There are several slight variations in the SOI values calculated at various centres.

The Southern Oscillation Index (SOI) is a standardized index based on the observed sea level pressure differences between Tahiti and Darwin, Australia. The SOI is a leading measure of the large The Southern Oscillation Index has been mentioned often in comments at WattsUpWithThat, in this series of blog posts about the upcoming El Niño. Curiously, Australia’s BOM Southern Oscillation Index for April 2014 is at a positive value that’s near to La Niña conditions, while the sea surfaces of the equatorial Pacific are now warming toward El… 20CR Climate Indices: Southern Annular Mode (SAM) Description: This mode describes low frequency variability of the Southern Hemisphere extratropics. A positive index (lower polar pressure) is associated with weaker, zonal winds in the extratropics. A negative value is associated with stronger zonal winds.
