Predicted Land Carbon Dynamics Are Strongly Dependent on the Numerical Coupling of Nitrogen Mobilizing and Immobilizing Processes: A Demonstration with the E3SM Land Model
Publisher: American Meteorological Society
Abstract: AbstractWhile coupling carbon and nitrogen processes is critical for Earth system models to accurately predict future climate and land biogeochemistry feedbacks, it has not yet been analyzed how numerical methods that land ...
Analysis of Permafrost Thermal Dynamics and Response to Climate Change in the CMIP5 Earth System Models
Publisher: American Meteorological Society
Abstract: he authors analyze global climate model predictions of soil temperature [from the Coupled Model Intercomparison Project phase 5 (CMIP5) database] to assess the models? representation of current-climate soil thermal dynamics ...
Local and Remote Climate Impacts from Expansion of Woody Biomass for Bioenergy Feedstock in the Southeastern United States
Publisher: American Meteorological Society
Abstract: any efforts have been taken to find energy alternatives to reduce anthropogenic influences on climate. Recent studies have shown that using land for bioenergy plantations may be more cost effective and provide a greater ...
Interannual Variation in Hydrologic Budgets in an Amazonian Watershed with a Coupled Subsurface–Land Surface Process Model
Publisher: American Meteorological Society
Abstract: AbstractThe central Amazon forest is projected to experience larger interannual precipitation variability, with uncertain impacts on terrestrial hydrologic fluxes. How surface runoff, groundwater, and evapotranspiration ...
Spatiotemporal Variations in Growing Season Exchanges of CO2, H2O, and Sensible Heat in Agricultural Fields of the Southern Great Plains
Publisher: American Meteorological Society
Abstract: Climate, vegetation cover, and management create finescale heterogeneity in unirrigated agricultural regions, with important but not well-quantified consequences for spatial and temporal variations in surface CO2, water, ...
Effects of Soil Moisture on the Responses of Soil Temperatures to Climate Change in Cold Regions
Publisher: American Meteorological Society
Abstract: t high latitudes, changes in soil moisture could alter soil temperatures independently of air temperature changes by interacting with the snow thermal rectifier. The authors investigated this mechanism with model experiments ...
The Rainfall Sensitivity of Tropical Net Primary Production in CMIP5 Twentieth- and Twenty-First-Century Simulations
Publisher: American Meteorological Society
Abstract: n this study, the authors used the relationship between mean annual rainfall (MAR) and net primary production (NPP) (MAR?NPP) observed in tropical forests to evaluate the performance (twentieth century) and predictions ...
