The interannual variability of tropical climates, including the tropical Marine climate, is best reflected in the rainfall activity of a given area. The effects of such variability are manifested in a number of ways on the physical landscape. However, this study focused on the ways in which the variability of the rainfall received on the Caribbean island of Trinidad, influenced the resulting streamflow discharges for different basins on the island. Various techniques such as time series analysis and spectral analysis, were used to identify the physical mechanisms, both local and non-variations in the regimes, such that the effects of easterly waves were observed in the rainfall; the Madden-Julian wave was identified in both the precipitation and streamflow regimes; there was evidence of a faster 14-25 day oscillation; and finally, the migration of the Intertropical Convergence Zone was found to be quasi-periodic in nature.
