What marine factors affect weather in Jamaica?
In-s [12.5K]
Weather in Jamaica is influenced by Inter-tropical convergence zone and relief. The marine factor is the warm ocean surrounding the island bringing warm moisture laden air to shore. The ITCZ influences the region in the summer time and it is the zone where the north east and southeast trades meet. Winds bring warm moisture laden air to shore. These winds meet mountain barriers and lead to the occurrence of relief rainfall, with more rain on windward slopes and less on leeward slopes.
