Spatial and Scale‐Dependent Controls on North American Pan‐Arctic Minimum River Discharge
Spatial patterns of minimum monthly river discharge in the N orth A merican P an‐ A rctic and its potential controls are explored with geographically weighted regression ( GWR ). Minimum discharge is indicative of soil water conditions; therefore, understanding spatial variability of its controls ma...

Spatial patterns of minimum monthly river discharge in the N orth A merican P an‐ A rctic and its potential controls are explored with geographically weighted regression ( GWR ). Minimum discharge is indicative of soil water conditions; therefore, understanding spatial variability of its controls may provide insights into patterns of hydrologic change. Here, GWR models are applied to determine a suitable combination of independent variables selected from a set of eight variables. A model specification with annual mean river discharge, temperature at time of minimum discharge, and biome describes well the spatial patterns in minimum discharge. However, minimum discharge in larger watersheds is influenced more by temperature and biome distributions than it is in small basins, suggesting that scale is critical for understanding minimum river discharge.
