Abstract :
Vorticity produced by the gap winds through the Central American Mountains over the Gulfs of Papagayo and Tehuantepec is observed to contribute to tropical cyclogenesis in the Eastern Pacific Basin. Interactions between the gap wind induced vorticity, ITCZ, and monsoon trough is also investigated. It is found that the majority of the Tropical Cyclones investigated in this study occur while the monsoon trough is present. Contributions from the gap winds are also observed to occur more frequently while the monsoon trough is present.
