Global Wet/Dry Patterns and Mechanisms Since the Last Glacial Maximum: A Key to Future Projection
Abstract Investigating the response mechanisms of long‐term global wet/dry pattern changes to cold/warm periods and climate forcings can provide scientific supports for the projection of future wet/dry patterns in the context of global warming. Here we present a systematic assessment into the respon...
