“…ENSO as an event of the ocean and atmosphere interactions that produce climatic variations in the tropical Pacific Ocean (Muhammad et al 2017). Meanwhile, the IOD phenomenon is an event from the interaction of the ocean and the atmosphere in the tropical Indian Ocean, which has a strong impact on the Indian Ocean region (Saji et al 1999;Yang et al 2019).…”

Abstract. Wijaya A, Zakiyah U, Sambah AB, Setyohadi D. 2020. Spatio-temporal variability of temperature and chlorophyll-a concentration of sea surface in Bali Strait, Indonesia. Biodiversitas 21: 5283-5290. The Bali Strait is influenced by seasonal and inter-annual systems. El Nino-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) are climate variabilities that affect water conditions. The knowledge about influence of ENSO and IOD variations on the fertility of waters in the Bali Strait is still lacking. The purpose of this study was to determine the effect of seasonal and inter-annual variability on the variability of Sea Surface Temperature (SST) and Sea Surface Chlorophyll-a (SSC) in the Bali Strait. This study applied SST and SSC data collected from the Aqua/Terra MODIS satellite, as well as the ENSO and IOD indices during March 2000-December 2019. The results described that the effect of ENSO on SST and SSC was low and IOD on SST and SSC was quite high. The effect was quite high between IOD and SST anomaly of-0.401. Seasonal variations indicate the abundance of high SSC and low SST in the southeast monsoon (JJA) which characterizes upwelling. Meanwhile, in the northwest monsoon (DJF), SSC was low and SST was high which characterizes downwelling. This condition cannot separate from the monsoonal process that occurred in the Bali Strait. The inter-annual variation showed that in the strong El Nino period and IOD (+) triggers a negative SST anomaly and a positive SSC results in strong upwelling, while in the strong La Nina period and strong IOD (-) triggers a positive SST anomaly and a negative SSC results in downwelling. The inter-annual variability of SSC influenced by IOD rather than ENSO. This condition indicates that the ENSO/IOD event changes the period of SSC concentration.

“…Posisi ini juga diapit oleh benua yaitu benua Asia dan benua Australia dan samudera yaitu samudera Pasifik dan samudera Hindia yang menjadikan Indonesia sebagai pusat perpindahan massa air di berbagai kedalaman (Ariska et al, 2022). Peristiwa kejadian El Nino-Southern Oscillation (ENSO) dan Madden-Julian Oscillation (MJO) merupakan dua faktor penting dalam sistem iklim global (Muhammad et al, 2017). ENSO adalah suatu pola perubahan suhu permukaan laut di kawasan Samudra Pasifik yang memiliki efek dominan terhadap variabilitas iklim di berbagai belahan dunia, termasuk Provinsi Riau (Purwaningsih et al, 2020).…”

El Nino-Southern Oscillation (ENSO) and Madden-Julian Oscillation (MJO) events are significant factors in the global climate system. Riau Province, located on the island of Sumatra, is highly influenced by these phenomena. This study collects climate data from weather stations in Riau Province and reliable sources for ENSO and MJO indices. Statistical analyses, including correlation and regression, are employed to determine the relationship between climate variables in Riau Province and ENSO and MJO. Based on data from 2001-2019, the results reveal a medium category correlation value (r = 0.452) with coefficients a and b of 1.288 and 0.089, respectively. The increased MJO value contrasts with the rainfall during the 2001-2019 timeframe. This information serves as a reference for understanding the ENSO and MJO phenomena in the Riau region.
