Short summary
To investigate the effect of groundwater flow on the active layer on slopes in permafrost landscapes, we conducted several modeling experiments. We find that groundwater moving downslope in the subsurface causes areas uphill to be warmer than downhill. This effect is explained by differences in heat capacity, conductivity, and infiltration. Therefore, in a changing climate, higher soil moisture could have a cooling effect on the active layer and attenuate warming from higher air temperatures.
