Systematic Underestimation of Nonlinear and Synergistic Soil Moisture‐Precipitation Coupling in Convection‐Permitting Models
Soil moisture‐precipitation coupling critically shapes Earth's water and energy cycles, yet it remains difficult to quantify because land‐atmosphere interactions are nonlinear, multivariate, and state‐dependent. This study applies the High‐Dimensional Model Representation (HDMR) framework to observation‐based data sets...
