Journal: :Paleoceanography and paleoclimatology 2022

Here, we compare the ocean overturning circulation of early Eocene (47–56 Ma) in eight coupled climate model simulations from Deep-Time Model Intercomparison Project (DeepMIP) and investigate causes observed inter-model spread. The most common global meridional (MOC) feature these is anticlockwise bottom cell, fed by sinking Southern Ocean. In North Pacific, one (GFDL) displays strong deepwater...

This modeling study focused on the hydrological and water quality effects of controlled drainage (CD) when operated using a subsurface system in an agricultural field Wielkopolska region. The DRAINMOD hydrologic model was well calibrated validated experimental field. used performance CD free (FD) combinations (108 27, respectively) near-future climate change scenario. objective to understand po...

East Asian Meiyu simulated by 35 global atmospheric models from the 6th Coupled Model Intercomparison Project (CMIP6)/Atmospheric (AMIP) were systematically evaluated for 1998–2014. The results show that most of CMIP6/AMIP can hardly reproduce observed spatial pattern and interannual variability Meiyu. is relatively better over Southern Korea Japan where 14 out have realistically precipitation,...

Journal: :Fisheries Oceanography 2021

Many fish species are shifting spatial distributions in response to climate change, but projecting these shifts and measuring their impact at fine scales challenging. We present a simulation that projects change fishery landings due distribution shifts, by combining regional ocean biogeochemical models (forced three earth system models, ESMs: GFDL-ESM2M, HadGEM2-ES, IPSL-CM5A-MR), correlative f...

The equatorial Pacific is a region with strong negative feedbacks. Yet coupled general circulation models (GCMs) have exhibited a propensity to develop a significant SST bias in that region, suggesting an unrealistic sensitivity in the coupled models to small energy flux errors that inevitably occur in the individual model components. Could this “hypersensitivity” exhibited in a coupled model b...

We use long-term, coincident O3 and temperature measurements at the regionally representative US Environmental Protection Agency Clean Air Status and Trends Network (CASTNet) over the eastern US from 1988 through 2009 to characterize the surface O3 response to year-to-year fluctuations in weather, for the purpose of evaluating global chemistry-climate models. We first produce a monthly climatol...
