Mechanisms of Subantarctic Mode Water re-emergence in a hybrid-coordinate global GCM
This study seeks to investigate the global circulation and re-emergence of Subantarctic Mode Water (SAMW), which is thought to be important in providing the source of nutrients to drive biological production over large proportions of the world ocean. For this purpose, the HYbrid isopycnic-cartesian …

Water Level Quantiles Of Devils Lake Under Down-Scaled Gcm Predictions Using A Coupled Hydro-Climatic Model
… the feasibility of using spatially distributed GCM data with a well calibrated hydro-climatic model to predict the probable flood severities. A temperature-based evaporation prediction model is also developed to simulate the outflow from the terminal lake. Future hydrology of the basin and lake …

Improving Our Understanding of Atmospheric Aerosols and Their Climate Effects: Implications for Satellite Retrievals and GCM Simulations
… aerosol parameters are tested using the GISS GCM. Among the three perturbed parameters, AOD, SSA and asymmetry parameter g, DRF appears to be most sensitive to SSA. Moreover, changing aerosol dry sizes result in larger fluctuation in DRF than the previous three parameters. Based on the …

Forecasting of rainfall using statistical downscaling model (SDSM) – general circulation model (GCM) for future estimation of rainwater harvesting
… investigated by using General Circulation Model (GCM) on the availability of daily simulation for three representative concentration pathways (RCP) scenarios, RCP2.6, RCP4.5 and RCP8.5 for interval year of Δ2030, Δ2050 and Δ2080. In addition, the annual future rainfall trend and harvested …

Characterization of Cis-Regulatory Elements Controlling Repo Transcription in Drosophila Melanogaster
The glial cells missing (gcm) gene has been identified as a "master regulator" of glial cell fate in the fruit fly Drosophila . However, the gcm gene is also expressed in and required for the development of larval macrophages and tendon cells, and lamina neurons in the adult CNS. Thus, the Gcm …

Understanding the Maintenance and Seasonal Transitions of the Climatological Stationary Waves in the Atmosphere
The deficiency of the GCM in simulating the observed reanalysis stationary waves mainly originates from the deficiencies of the GCM simulated diabatic heating field. Therefore, a significant improvement in the parameterization schemes and spatial resolution of the GCM is needed for the GCM to …

Application of an inverse model in the community modeling effort results
… first tested in a non-eddy resolving numerical GCM ocean. Numerical/scale analyses are used to test whether the inverse model properly represents the GCM ocean. Experiments show how biased answers could result from an incorrect model, and how a correct model must produce the right answers. When …

Abrupt climate change in the Atlantic Ocean during the last 20,000 years : insights from multi-element analysis of benthic and planktic foraminifera and coupled OA-GCM
… cores, as well as output from a coupled OAGCM, were used to investigate the magnitude and distribution of the oceanic response to abrupt climate events of the past 20 kyr. The study addressed three major questions: 1) What is the magnitude of high-latitude sea surface temperature and …

Bias Correction and Downscaling of Climate Model Outputs Required for Impact Assessments of Climate Change in the U.S. Northeast
<p>Global Climate Models (GCMs) are the typical sources of future climate data required for impact assessments of climate change. However, GCM outputs are related to model-related uncertainties and involve a great deal of biases. Bias correction of model outputs is, therefore, necessary before …
