Abstract

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
