The association between the southern oscillation index (SOI, an index based on air pressure differences between the Pacific and Indian Oceans which has been linked to periods of drought in northern Australia) and cases of seroconversion to bluetongue viruses were examined. More cases occurred during ...
Warm El Nio-Southern Oscillation (ENSO) events, indicated by large negative values of the Southern Oscillation Index (SOI), are significantly correlated with decreases in the frequency of strong and violent tornadoes (Fujita scale F2 to F5) between February and July in two regions of the south-...
To track EN, LN, and other climate events, a number of SLP-based indices have been created; for example, the Southern Oscillation Index (SOI) (Trenberth & Shea, 1987), the North Atlantic Oscillation (NAO) Index (Barnston and Livezey, 1987, Hurrell, 1995), and the North Pacific (NP)...
Madhuri N. Kulkarni & Devendraa Siingh Like the southern oscillation index (SOI) based on the pressure difference between Tahiti (17.5°S, 150°W) and Darwin (12.5°S, 130°E), we propose the new atmospheric electrical index (AEI) taking the difference in the model calculated ...
A previous study demonstrated that the location of the salinity front is closely related to the Southern Oscillation Index (SOI)3. The salinity front generally shifts to a lower latitude during El Niño, resulting in a smaller eel catch3. However, closer inspection indicates that the significant...
This study examines the variability of the southwest Western Australian (SWWA) shelf and nearshore wind wave climate and its relationship to southern hemisphere climate variability represented by various atmospheric indices: the southern oscillation index (SOI), the Southern Annular Mode (SAM), the ...
The Southern Oscillation Index (SOI) is closely related to the variability in the shoreline. Time-lagged cross-correlations between monthly beach shoreline positions and the SOI were calculated to investigate the presence of stronger cross-correlations between the beach shoreline and the SOI; the ...
The effect of the Southern Oscillation on daily precipitation in the southwestern United States is examined by using the Southern Oscillation Index (SOI) to perturb parameters of a stochastic daily precipitation model. Daily precipitation is modeled with a Markov chain-mixed exponential model and ...
Summer precipitation trends and teleconnections with global sea-surface temperatures (SST) and the Southern Oscillation Index (SOI) from 1961 to 2010 were investigated by Mann-Kendall test and Pearson product-moment correlation analysis. The results show that the northwest part (Zone 1) had a non-...
We tested the correlations between the dry-season SC extent (in the 3 macrozones considered in this study) and 3 climate indices: the SST anomaly in the Niño 1 + 2 region (0–10°S, 90°W–80°W)41, the Southern Oscillation Index (SOI)42, and the SAM index43. Weekly SST...
