The influence of the tropical Atlantic versus the tropical Pacific on the Caribbean rainfall. Submitted to Journal of Geophysical Research
[1] The Caribbean rainfall season runs from May through November and is distinctly bimodal in nature. The bimodality allows for a convenient division into an early season (May–June–July) and a late season (August–September–October). Evidence suggests that interannual variability in the early season...

[1] The Caribbean rainfall season runs from May through November and is distinctly bimodal in nature.

Evidence suggests that interannual variability in the early season is influenced strongly by anomalies in the sea surface temperatures of the tropical North Atlantic, with positive anomalies over a narrow latitudinal band (0–20N) being associated with enhanced Caribbean rainfall. The coincidence of this band with the main development region for tropical waves suggests a modification of the development of the waves by the warmer tropical Atlantic.
