Give geographical reasons:

Tropical cyclones occur rarely in Brazil.

Tropical cyclones are localized, very intense low-pressure wind system, forming over tropical cyclones. In the coastal regions near the equator in Brazil, differences in temperatures are negligible. The winds move in the vertical direction in this region. Similarly, the convergence zone of the trade winds is weak here. These are a few conditions which need to be fulfilled for the formation of tropical cyclones, and since they are not fulfilled, tropical cyclones rarely visit the coasts of Brazil.
