RISThe Seasonal Response of the Held-Suarez Climate Model to Prescribed Ocean Temperature Anomalies. Part II: Dynamical Analysis
Publisher: American Meteorological Society
Abstract: From an analysis of the heating associated with equatorial, subtropical and midlatitude ocean temperature anomalies in the Held-Suarez climate model, it is found that the magnitude of increase in vertical motion per unit ...
On the Interaction of Surface Heating Anomalies with Zonally Symmetric and Asymmetric Atmospheric Flows
Publisher: American Meteorological Society
Abstract: The interaction of different zonally symmetric and asymmetric flows with heating arising from a prescribed anomaly in surface temperature is investigated in linear and nonlinear quasi-geostrophic models. In cases of zonally ...
Documentation of the AMIP Models on the World Wide Web
Publisher: American Meteorological Society
Abstract: Summary documentation of the numerics, dynamics, and physics of models participating in the Atmospheric Model Intercomparison Project is now available on the Internet's World Wide Web. In this article the principal attributes ...
Reproducibility of Seasonal Land Surface Climate
Publisher: American Meteorological Society
Abstract: In this study, the sensitivity of the continental seasonal climate to initial conditions is estimated from an ensemble of decadal simulations of an atmospheric general circulation model with the same specifications of ...
An Application of a Simple Coupled Ocean-Atmosphere Model to the Study of Seasonal Climate Prediction
Publisher: American Meteorological Society
Abstract: A 50-year integration of a simple two-layer atmospheric model coupled to a prognostic-depth ocean mixed layer is used for a preliminary exploration of the potential for global climate prediction on seasonal to interannual ...
The Seasonal Response of the Held-Suarez Climate Model to Prescribed Ocean Temperature Anomalies. Part I: Results of Decadal Integrations
Publisher: American Meteorological Society
Abstract: A ten-year integration of the Held-Suarez climate model with simplified continents and prescribed, but seasonally varying, ocean temperatures produces mean climatic states that are qualitatively similar to observed seasonal ...
Coherent Fluctuations of Fxtratropical Geopotential Height and Tropical Convection in Intraseasonal Time Scales
Publisher: American Meteorological Society
Abstract: Coherent fluctuations between extratropical circulation and tropical conviction in the intraseasonal time scale are studied. Possible relationships between 500-mb height field and outgoing longwave radiation (OLR) are ...
Regional Differences in the Influence of Irrigation on Climate
Publisher: American Meteorological Society
Abstract: A global climate model experiment is performed to evaluate the effect of irrigation on temperatures in several major irrigated regions of the world. The Community Atmosphere Model, version 3.3, was modified to represent ...
Relative Contributions of Mean-State Shifts and ENSO-Driven Variability to Precipitation Changes in a Warming Climate
Publisher: American Meteorological Society
Abstract: l Niño?Southern Oscillation (ENSO) is an important driver of regional hydroclimate variability through far-reaching teleconnections. This study uses simulations performed with coupled general circulation models (CGCMs) to ...
Competing Influences of Anthropogenic Warming, ENSO, and Plant Physiology on Future Terrestrial Aridity
Publisher: American Meteorological Society
Abstract: AbstractThe 2011?16 California drought illustrates that drought-prone areas do not always experience relief once a favorable phase of El Niño?Southern Oscillation (ENSO) returns. In the twenty-first century, such an ...
