Ocean atmospheric phenomenon such as El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (DMI) have an impact on global level climatic patterns and agriculture. The climate and agricultural activities of Sri Lanka, which is a tropical island in the Indian Ocean, mainly depends on the amount and the distribution of rainfall. The objective of this study was to assess the impact of ENSO and DMI on growing seasonal characteristics of Batalagoda, Sri Lanka. The growing seasonal characteristics such as the onset, retreat, length of the season, seasonal rainfall and rainy days were initially assessed using Instat Statistical Programme. Pearson correlation analysis was then performed to check their relationship with oceanic indices. The Multivariate ENSO Index and DMI did not show a significant correlation (p > 0.05) between onset, retreat and length of the season. However, the retreat of the season showed a significant (p < 0.05) relationship with Southern Oscillation Index (SOI). Both SOI and MEI showed significant (p < 0.05) correlation with the growing seasonal rainfall. Due to some signals of the impact of oceanic indices on the growing seasonal characteristics of Batalagoda, further studies are needed to be carried out throughout the county using the similar approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
