This study implemented a coupled SWAT-FEM simulation model to evaluate the impacts of land use cover and climate change scenarios (LCS) on water resources river catchments in Chennai, India. The data were obtained by merging source from National Remote Sensing Centre (NRSC) International Water Management Institute (IWMI). Climate simulations four global models (GCM), including GFDL Baseline Sce...

Abstract. The sea level over the tropical Pacific is a key indicator reflecting vertically integrated heat distribution ocean. Here, we use Geophysical Fluid Dynamics Laboratory global ocean–sea ice model (GFDL-OM4) forced by both Coordinated Ocean-Ice Reference Experiment (CORE) and Japanese 55-year Reanalysis (JRA-55)-based surface dataset for driving models (JRA55-do) atmospheric states (Oce...

Abstract. Two-way multiple same-level and telescoping grid nesting capabilities are implemented in the Geophysical Fluid Dynamics Laboratory (GFDL)'s Finite-Volume Cubed-Sphere Dynamical Core (FV3). Simulations performed within GFDL's System for High-resolution modeling Earth-to-Local Domains (SHiELD) using global regional nest configurations. Results show that multi-level nests were able to ca...

Amongst the impacts of climate change, those arising from extreme hydrological events are expected to cause greatest impacts. To assess changes in temperature and precipitation their on discharge upper Yangtze Basin pre-industrial end 21st century, four models were integrated with global models. Results indicated that mean was simulated increase slightly for all forced by during 1771–1800 1871–...

Climate change in the Indian Himalayan region is being manifested loss of glaciers and altered patterns monsoon rainfall. Simultaneously, rapid population growth together with economic development are increasing sectoral water demands changing land use patterns. This study investigated impact this complex interplay on resources Beas-Sutlej system. The GFDL-CM3 model was used to describe RCP8.5 ...

Abstract The characteristics of tropical mesoscale convective systems (MCSs) simulated with a finer-resolution (~50-km) version the Geophysical Fluid Dynamics Laboratory (GFDL) AM4 model are evaluated by comparing comprehensive long-term observational dataset. It is shown that can capture various aspects MCSs reasonably well. spatial distribution broadly in agreement observations. This also tru...

Abstract There is a lack of consensus on whether North Atlantic tropical cyclone (TC) outer size and structure (i.e., change in winds with increasing radius from the TC) will differ by late twenty-first century. Hence, this work seeks to examine TC wind field century using multiple simulations under CMIP3 SRES A1B CMIP5 RCP4.5 scenarios. Specifically, our analysis examines data GFDL High-Resolu...
