[1] In this second part of the two-part series, we discuss the formulation and implementation of groundwater processes into an existing climate model, by linking a groundwater reservoir and a rivers-lakes reservoir with its land surface scheme. We present the parameterization and validation of these processes with river flow and soil moisture observations. We use the new scheme as a tool to investigate the role of the groundwater reservoir in controlling the spatial and temporal structure of… 

Climate–soil–vegetation control on groundwater table dynamics and its feedbacks in a climate model

Among the three dynamically linked branches of the water cycle, including atmospheric, surface, and subsurface water, groundwater is the largest reservoir and an active component of the hydrologic

Effects of water table dynamics on regional climate

[1] Groundwater is an important component of the hydrologic cycle, and its anomaly will result in variations of soil moisture, water, and energy balances between the land surface and atmosphere,

Incorporating water table dynamics in climate modeling: 3. Simulated groundwater influence on coupled land‐atmosphere variability

[1] Using a coupled regional climate-hydrologic modeling system, RAMS-Hydro, we investigate the role of the water table dynamics in controlling soil moisture, evapotranspiration (ET), boundary layer

Effects of a groundwater scheme on the simulation of soil moisture and evapotranspiration over southern South America

AbstractThe effects of groundwater dynamics on the representation of water storage and evapotranspiration (ET) over southern South America are studied from simulations with the Noah-MP land surface

Groundwater influence on soil moisture memory and land–atmosphere fluxes in the Iberian Peninsula

Abstract. Groundwater plays an important role in the terrestrial water cycle, interacting with the land surface via vertical fluxes through the water table and distributing water resources spatially

SIMULATED WATER TABLE AND SOIL MOISTURE CLIMATOLOGY OVER NORTH AMERICA

We demonstrate the link between two terrestrial water reservoirs: the root-zone soil moisture and the groundwater, and contribute our simulated climatologic water table depth and soil moisture fields

The role of groundwater in the Amazon water cycle: 2. Influence on seasonal soil moisture and evapotranspiration

[1] We investigate the potential influence of groundwater on seasonal evapotranspiration (ET) in the Amazon using a coupled groundwater-surface water model (LEAF-Hydro-Flood) forced with ERA-Interim
