RISDo We Require Adiabatic Dissipation Schemes in Eddy-Resolving Ocean Models?
Publisher: American Meteorological Society
Abstract: Use of horizontal diffusion of temperature and salinity in numerical ocean models causes spurious diapycnal transfers?the ?Veronis effect??leading to erosion of the thermocline and reduced poleward heat transports. The ...
The Impact of a Bottom Boundary Layer Scheme on the North Atlantic Ocean in a Global Coupled Climate Model
Publisher: American Meteorological Society
Abstract: Although the overflow and descent of cold, dense water across the Greenland?Iceland?Scotland ridge is the principal means for the maintenance of the thermohaline circulation in the North Atlantic Ocean, this feature is not ...
Potential Underestimation of Future Mei-Yu Rainfall with Coarse-Resolution Climate Models
Publisher: American Meteorological Society
Abstract: AbstractThe amount of rainfall during June and July along the mei-yu front contributes about 45% to the total summer precipitation over the Yangtze River valley. How it will change under global warming is of great concern ...
Response of Tropical Cyclones to Idealized Climate Change Experiments in a Global High-Resolution Coupled General Circulation Model
Publisher: American Meteorological Society
Abstract: he authors present an assessment of how tropical cyclone activity might change owing to the influence of increased atmospheric carbon dioxide concentrations, using the U.K. High-Resolution Global Environment Model (HiGEM) ...
An Intercomparison of a Bryan–Cox-Type Ocean Model and an Isopycnic Ocean Model. Part I: The Subpolar Gyre and High-Latitude Processes
Publisher: American Meteorological Society
Abstract: This paper describes a model intercomparison between a Bryan-Cox-type ocean model and an isopycnic-coordinate ocean model. The two models are integrated for 30 years on a domain of the North Atlantic stretching from 20°S ...
An Intercomparison of a Bryan-Cox-Type Ocean Model and an Isopycnic Ocean Model. Part II: The Subtropical Gyre and Meridional Heat Transport
Publisher: American Meteorological Society
Abstract: In a companion paper, two ocean general circulation models were implemented in order to simulate and intercompare the main features of the North Atlantic circulation: the Atlantic Isopycnic Model (AIM) and the Hadley Centre ...
Simulation of the Global ENSO–Tropical Cyclone Teleconnection by a High-Resolution Coupled General Circulation Model
Publisher: American Meteorological Society
Abstract: his study assesses the influence of the El Niño?Southern Oscillation (ENSO) on global tropical cyclone activity using a 150-yr-long integration with a high-resolution coupled atmosphere?ocean general circulation model ...
Investigating Global Tropical Cyclone Activity with a Hierarchy of AGCMs: The Role of Model Resolution
Publisher: American Meteorological Society
Abstract: he ability to run general circulation models (GCMs) at ever-higher horizontal resolutions has meant that tropical cyclone simulations are increasingly credible. A hierarchy of atmosphere-only GCMs, based on the Hadley ...
Realism of Rainfall in a Very High-Resolution Regional Climate Model
Publisher: American Meteorological Society
Abstract: he realistic representation of rainfall on the local scale in climate models remains a key challenge. Realism encompasses the full spatial and temporal structure of rainfall, and is a key indicator of model skill in ...
Indian Ocean Climate and Dipole Variability in Hadley Centre Coupled GCMs
Publisher: American Meteorological Society
Abstract: Prediction of Indian Ocean interannual variability may be limited by the systematic biases in coupled GCMs or by a lack of resolution of the processes involved. In particular, little is known about the impact of ocean ...
