RISThe Dependence of Climate Sensitivity on the Horizontal Resolution of a GCM
Publisher: American Meteorological Society
Abstract: The impact of changing the horizontal resolution of a version of the Hadley Centre GCM is investigated in present-day and 2 ? CO2 climate simulations. The use of higher resolution generally produces favorable changes. The ...
Carbon Dioxide and Climate. The Impact of Cloud Parameterization
Publisher: American Meteorological Society
Abstract: The importance of the representation of cloud in a general circulation model is investigated by utilizing four different parameterization schemes for layer cloud in a low-resolution version of the general circulation model ...
Transient Climate Change in the Hadley Centre Models: The Role of Physical Processes
Publisher: American Meteorological Society
Abstract: A comparison of the response to increasing greenhouse gas concentrations of two versions of the Met Office's (Hadley Centre) coupled atmosphere?ocean model reveals differences that result in large local variations in the ...
On Surface Temperature, Greenhouse Gases, and Aerosols: Models and Observations
Publisher: American Meteorological Society
Abstract: The effect of changes in atmospheric carbon dioxide concentrations and sulphate aerosols on near-surface temperature is investigated using a version of the Hadley Centre atmospheric model coupled to a mixed layer ocean. ...
Analysis and Reduction of Systematic Errors through a Seamless Approach to Modeling Weather and Climate
Publisher: American Meteorological Society
Abstract: The reduction of systematic errors is a continuing challenge for model development. Feedbacks and compensating errors in climate models often make finding the source of a systematic error difficult. In this paper, it is ...
CMIP5 Scientific Gaps and Recommendations for CMIP6
Publisher: American Meteorological Society
Abstract: he Coupled Model Intercomparison Project (CMIP) is an ongoing coordinated international activity of numerical experimentation of unprecedented scope and impact on climate science. Its most recent phase, the fifth phase ...
The Transpose-AMIP II Experiment and Its Application to the Understanding of Southern Ocean Cloud Biases in Climate Models
Publisher: American Meteorological Society
Abstract: he Transpose-Atmospheric Model Intercomparison Project (AMIP) is an international model intercomparison project in which climate models are run in ?weather forecast mode.? The Transpose-AMIP II experiment is run alongside ...
The Benefits of Global High Resolution for Climate Simulation: Process Understanding and the Enabling of Stakeholder Decisions at the Regional Scale
Publisher: American Meteorological Society
Abstract: AbstractThe time scales of the Paris Climate Agreement indicate urgent action is required on climate policies over the next few decades, in order to avoid the worst risks posed by climate change. On these relatively short ...
The New Hadley Centre Climate Model (HadGEM1): Evaluation of Coupled Simulations
Publisher: American Meteorological Society
Abstract: A new coupled general circulation climate model developed at the Met Office's Hadley Centre is presented, and aspects of its performance in climate simulations run for the Intergovernmental Panel on Climate Change Fourth ...
