Equatorial regions receive rainfall throughout the year and thus there is no dry season. Average annual rainfall exceeds 200 cm to 250cm. Even the driest month of the year receives rainfall more than 6 cm. Iquitos (Peru), Akassa and Ocean Island receive 261 cm, 366cm and 213cm of rain per annum respec­tively. Though most of the rainfall occurs through convective mechanism but wherever mountain barrier becomes effective the amount of rainfall increases substantially.
