Averaged across the whole basin, there are two major rainfall seasons in March to May and September to November. In both hemispheres the rainfall maximises in September to November, at above 210 mm per month. In northern hemisphere winter, rainfall is relatively low to the north of the equator (<80 mm per month). In southern hemisphere winter, rainfall is instead lower to the south of the equator (<80 mm per month). The annual rhythm of the wind systems which carry water vapour account for the rainfall seasonality. Much of the rainfall is derived from large

and the Democratic Republic of the Congo in May 2002. The World Bank agreed to provide $90 million of development aid to Democratic Republic of the Congo with the provision that the government did not issue any new concessions granting logging companies rights to exploit the forest. The deal also prohibited the renewal of existing concessions.
The government has written a new forestry code that requires companies to invest in local development and follow a sustainable, 25-year cycle of rotational logging. When a company is granted a concession from the central government to log in Congo, it must sign an agreement with the local chiefs and hereditary land owners, who give permission for it to extract the trees in return for development packages. In theory, the companies must pay the government nearly $18 million rent per year for these concessions, of which 40% should be returned to provincial governments for investment in social development of the local population in the logged areas.
