Stratospheric injections of sulfur dioxide from major volcanic eruptions perturb the Earth's global radiative balance and dominate variability in stratospheric loading. The atmospheric component GFDL Earth System Model (ESM4.1) uses a bulk aerosol scheme previously prescribed distribution optical properties stratosphere. To quantify contributions to cycle resulting climate impact, we modified E...

Quantitative information on soil loss is relevant for devising conservation and crop management strategies to ensure sustainable fertility production. Estimations from runoff/erosion plots are expensive laborious thus requiring the exploration of other less but reliable methods such as modeling. This study aimed estimate current future rates planning toward production in semi-deciduous forest z...

An intermediate complexity coupled oceanatmosphere-land-ice model, based on the Geophysical Fluid Dynamics Laboratory (GFDL) Flexible Modelling System (FMS), has been developed to study mechanisms of oceanatmosphere interactions and natural climate variability at interannual to interdecadal and longer time scales. The model uses the three-dimensional primitive equations for both ocean and atmos...

The climate response to idealized changes in the atmospheric CO2 concentration by the new GFDL climate model (CM2) is documented. This new model is very different from earlier GFDL models in its parameterizations of subgrid-scale physical processes, numerical algorithms, and resolution. The model was constructed to be useful for both seasonal-to-interannual predictions and climate change resear...

We investigated the influence of spatial aggregation on modeled forest responses to climate change by applying the process-based Terrestrial Ecosystem Model (TEM) to a fine resolution spatial grid (100 km2) and to a coarse resolution spatial grid (2500 km2). Three climate scenarios were simulated: baseline (present) climate with ambient CO2 and 2 future climates derived from the general circula...

Freebase is a practical, scalable, graph-shaped database of structured general human knowledge, inspired by Semantic Web research and collaborative data communities such as the Wikipedia. Freebase allows public read and write access through an HTTP-based graph-query API for research, the creation and maintenance of structured data, and application building. Access is free and all data in Freeba...

Integrations of coupled climate models with mixed-layer and fixed-current ocean components are used to explore the climatic response to varying magnitudes of ocean circulation. Four mixed-layer ocean experiments without ocean heat transports are performed using two different atmosphere–land components—the new GFDL AM2 and the GFDL Manabe Climate Model (MCM)—and two different sea ice components,...

We used the Terrestrial Ecosystem Model (TEM, version 4.0) to estimate net primary production (NPP) in China for contemporary climate and NPP responses to elevated CO2 and climate changes projected by three atmospheric general circulation models (GCMs): Goddard Institute for Space Studies (GISS), Geophysical Fluid Dynamic Laboratory (GFDL) and Oregon State University (OSU). For contemporary cli...

Abstract This study examines the climatology and dynamics of atmospheric blocking, general circulation features that influence blocks in GFDL’s atmosphere-only (AM4) coupled atmosphere–ocean (CM4) comprehensive models. We compare AM4 CM4 with reanalysis, focusing on winter Northern Hemisphere. Both models generate correct blocking planetary-scale signatures stationary wave. However, at regional...

[1] We use a 20-year record of HIRS radiance measurements to evaluate the fidelity of interannual co-variability of tropical humidity and temperature in the reanalyses and GFDL AM2 simulations. Large inconsistencies between the NCEP and ECMWF reanalyses are found as are disagreements between the reanalyses and AM2 simulations. The largest discrepancies occur in the middle and upper troposphere ...
