The Adequacy of Observing Systems in Monitoring the Atlantic Meridional Overturning Circulation and North Atlantic Climate
Publisher: American Meteorological Society
Abstract: The Atlantic meridional overturning circulation (AMOC) has an important influence on climate, and yet adequate observations of this circulation are lacking. Here, the authors assess the adequacy of past and current widely ...
Interdecadal Variations of the Thermohaline Circulation in a Coupled Ocean-Atmosphere Model
Publisher: American Meteorological Society
Abstract: A fully coupled ocean-atmosphere model is shown to have irregular oscillations of the thermohaline circulation in the North Atlantic Ocean with a time scale of approximately 50 years. The irregular oscillation appears to ...
Impact of Enthalpy-Based Ensemble Filtering Sea Ice Data Assimilation on Decadal Predictions: Simulation with a Conceptual Pycnocline Prediction Model
Publisher: American Meteorological Society
Abstract: he non-Gaussian probability distribution of sea ice concentration makes it difficult to directly assimilate sea ice observations into a climate model. Because of the strong impact of the atmospheric and oceanic forcing on ...
Past, Present, and Future Changes in the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: ons and numerical modeling experiments provide evidence for links between variability in the Atlantic meridional overturning circulation (AMOC) and global climate patterns. Reduction in the strength of the overturning ...
Climate Field Reconstruction under Stationary and Nonstationary Forcing
Publisher: American Meteorological Society
Abstract: The fidelity of climate reconstructions employing covariance-based calibration techniques is tested with varying levels of sparseness of available data during intervals of relatively constant (stationary) and increasing ...
Extreme North America Winter Storm Season of 2013/14: Roles of Radiative Forcing and the Global Warming Hiatus
Publisher: American Meteorological Society
Assessment of Twentieth-Century Regional Surface Temperature Trends Using the GFDL CM2 Coupled Models
Publisher: American Meteorological Society
Abstract: Historical climate simulations of the period 1861?2000 using two new Geophysical Fluid Dynamics Laboratory (GFDL) global climate models (CM2.0 and CM2.1) are compared with observed surface temperatures. All-forcing runs ...
Predicting a Decadal Shift in North Atlantic Climate Variability Using the GFDL Forecast System
Publisher: American Meteorological Society
Abstract: ecadal prediction experiments were conducted as part of phase 5 of the Coupled Model Intercomparison Project (CMIP5) using the GFDL Climate Model, version 2.1 (CM2.1) forecast system. The abrupt warming of the North Atlantic ...
GFDL's CM2 Global Coupled Climate Models. Part IV: Idealized Climate Response
Publisher: American Meteorological Society
Abstract: 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 ...
