What accounts for the two precipitation peaks in mbandaka?

The dual peaks of precipitation in Mbandaka, occurring from March to April and September to November, arise from the intertropical convergence zone.

The intertropical convergence zone is a slender belt found close to the equator. It is where the air masses from the northern and southern hemispheres converge, leading to decreased atmospheric pressure. Due to the interaction of these air masses within the intertropical convergence zone, lower air pressure often results in cooler air or increased rainfall, particularly in Mbandaka during the periods of March to April and, most notably, from September to November.

<span>Given that Mbandaka is situated at the center of the Tumba-Ngiri-Maindombe region, recognized as a Wetland of International Importance, there’s a significant likelihood for the area to receive over 60mm of rainfall annually, with temperatures ranging between 23 and 26 degrees Celsius.</span>
