The IOD is characterized by SST gradient index called the Dipole Mode Index (DMI). DMI is the difference of SST between the west and the east of Equatorial Indian Ocean. A positive DMI refers to the formation of SST in the western regional warmer than the east, and vice versa. Abstract: Various data sets related to the Indian Ocean Dipole Mode phenomenon. The Dipole Mode Index (DMI) is a measure of the anomalous zonal SST gradient across the equatorial Indian Ocean. It is defined as the difference between SST anomaly in a western (60E-80E,10S-10N) and an eastern (90E-110E,10S-0S) box. Regarding ENSO events that are related to the IOD 17,26, in order to isolate ENSO effects, a linear relation of Niño-3.4 with the DMI has been removed from the DMI, to obtain a residual index (i.e., DMI| Niño-3.4). As the IOD is weaker in boreal summer compared with boreal fall, no obvious correlation between DMI| Niño-3.4 and rainfall Results of the present study put forward important modulation effects by the Indian Ocean Dipole (IOD) mode. The observed sea level in the WTPO shows significant instantaneous and lagged correlations (around -0.60 and 0.40, respectively) with the IOD mode index (DMI).
Dipole Mode Index (DMI) Intensity of the IOD is represented by anomalous SST gradient between the western equatorial Indian Ocean (50E-70E and 10S-10N) and the south eastern equatorial Indian Ocean (90E-110E and 10S-0N). This gradient is named as Dipole Mode Index (DMI).

The ENSO forced IOD variability, represented as 27 Feb 2020 The monthly Dipole Mode Index time series reveals other extreme positive phase IOD events, like in 1994 and 1997, but 2019 brought the most 1 Jan 2015 s analysis, the IOD structure and impacts have been widely analyzed using the dipole mode index. (DMI; Saji et al. 1999). The DMI index Finally, the IOD negative phase is shown to have an effect on the wave significant wave height (Hs) was correlated with the Dipole Mode Index (DMI) at the between the climate indices and rainfall, so that multiple linear regression with lag Regarding IOD, the Dipole Mode Index (DMI) was used as an indicator of
Yearly changes in the Dipole Mode Index (DMI) - DMI is defined as the sea surface temperature anomaly difference between tropical western Indian Ocean and the southeastern Indian Ocean. Positive DMI values (red) point to a positive IOD year, and negative values (blue) to negative IOD years.
21 Oct 2016 ues of the MJO index, which favours high rainfall, as scale oscillations (ENSO/ SOI, IOD/DMI, QBO, SSN) and p value to test the hypothesis of 15 Jan 2016 and the IOD is examined through the DMI defined by. Saji et al. (1999). The IOB is characterized through the tropical Indian Ocean index (TIO; Dipole Mode Index (DMI) Intensity of the IOD is represented by anomalous SST gradient between the western equatorial Indian Ocean (50E-70E and 10S-10N) and the south eastern equatorial Indian Ocean (90E-110E and 10S-0N). This gradient is named as Dipole Mode Index (DMI). DIPOLE MODE INDEX. Intensity of the IOD is represented by anomalous SST gradient between the western equatorial Indian Ocean (50 o E-70 o E and 10 o S-10 o N) and the south eastern equatorial Indian Ocean (90 o E-110 o E and 10 o S-0 o N). This gradient is named as Dipole Mode Index (DMI).
