Clouds form, and precipitation occurs. Zambia, landlocked country in south-central Africa. Relief rainfall . Prevailing winds are not usually very strong and a lack of a great deal of dry fuel on the ground (since most areas are burnt annually it does not build up) means that the fires are not as devastating as in countries such as Australia and the south-western USA.
