Abstract
Two integrations of a global general circulation model, differing only in the prescribed surface albedo in the Sahara, show that an increase in albedo resulting from a decrease in plant cover causes a decrease in rainfall. Thus any tendency for plant cover to decrease would be reinforced by a decrease in rainfall, and could initiate or perpetuate a drought.
摘要
两段全球环流模型的整合，仅在撒哈拉沙漠的地表反照率规定上有所不同，表明由于植物覆盖减少导致的反照率增加会导致降雨量减少。因此，任何导致植物覆盖减少的趋势都会因降雨量减少而加剧，并可能引发或持续干旱。
