Interpluvial

Interpluvial refers to a period of drier conditions that occurs between pluvial periods, which are times of unusually heavy rainfall and increased lake levels in arid and semi-arid regions. These wetter pluvial periods are often associated with glacial periods in higher latitudes. During an interpluvial, the climate shifts, leading to reduced precipitation and a subsequent drop in lake levels, desertification, and the expansion of arid landscapes. Evidence for interpluvial periods is found in geological formations such as ancient lake shorelines, sediment deposits, and fossilized flora and fauna. Understanding interpluvials is crucial for reconstructing past climate changes and predicting future environmental responses to climatic shifts. The transition from a pluvial to an interpluvial period can have significant impacts on ecosystems and human settlements, potentially leading to resource scarcity and migration.
