The reason why cyclones do not originate in the South Atlantic and South Eastern Pacific regions in tropical latitudes is primarily due to the absence of land in those regions. Cyclones typically require the interaction between warm ocean waters and land masses to develop and strengthen. In the South Atlantic and South Eastern Pacific regions, there is a lack of significant land masses that can contribute to the formation and intensification of cyclones. While factors such as sea surface temperature, Inter Tropical Convergence Zone (ITCZ), and Coriolis force play important roles in cyclone formation in other regions, the absence of land is the main reason for the lack of cyclone activity in the mentioned regions.
