Abstract

Changes in rainfall patterns have a significant impact on agriculture and water management in arid regions such as Nusa Tenggara. Water availability in this region is highly dependent on rainfall, which is influenced by global climate phenomena such as El-Niño and the Indian Ocean Dipole (IOD). This study aims to analyze the characteristics of rainfall patterns and analyze the relationship between rainfall and the El-Niño and IOD phenomena. Daily rainfall data from three BMKG observation stations in West Nusa Tenggara and East Nusa Tenggara during the period 1983-2022 were used in the analysis. The Fast Fourier Transform (FFT) method is used to identify periodic cycles, while the Pearson correlation test is used to determine the relationship of rainfall with El-Niño and IOD. The analysis shows that the Nusa Tenggara region is characterized by a monsoonal rainfall pattern with an annual cycle (12 months). Peak rainfall occurs in January, while the dry season lasts from July to September. The correlation of rainfall with El-Niño shows a weak negative relationship, while the influence of IOD is very small and varies between locations. This research provides important insights for agricultural sector planning, drought risk mitigation and water resources management. By understanding rainfall patterns influenced by seasonal cycles and global climate phenomena, planting times can be optimized, thereby supporting the sustainability of the agricultural sector and food security in regions with high climate variability.
