Understanding the Sensitivity of Different Drought Metrics to the Drivers of Drought under Increased Atmospheric CO2
Publisher: American Meteorological Society
Abstract: perturbed physics Hadley Centre climate model ensemble was used to study changes in drought on doubling atmospheric CO2. The drought metrics analyzed were based on 1) precipitation anomalies, 2) soil moisture anomalies, ...
Evaluating Uncertainties in the Projection of Future Drought
Publisher: American Meteorological Society
Abstract: The uncertainty in the projection of future drought occurrence was explored for four different drought indices using two model ensembles. The first ensemble expresses uncertainty in the parameter space of the third Hadley ...
Using MICRO-SWEAT to Model Microwave Brightness Temperatures Measured during SGP97
Publisher: American Meteorological Society
Abstract: MICRO-SWEAT, a soil?vegetation?atmosphere transfer scheme (SWEAT) coupled with a microwave emission model, was used to predict the microwave brightness temperatures (TB) measured at El Reno, Oklahoma, during the Southern ...
Estimating the Permafrost-Carbon Climate Response in the CMIP5 Climate Models Using a Simplified Approach
Publisher: American Meteorological Society
Abstract: nder climate change, thawing permafrost may cause a release of carbon, which has a positive feedback on the climate. The permafrost-carbon climate response (?PF) is the additional permafrost-carbon made vulnerable to ...
Modeling the Recent Evolution of Global Drought and Projections for the Twenty-First Century with the Hadley Centre Climate Model
Publisher: American Meteorological Society
Abstract: Meteorological drought in the Hadley Centre global climate model is assessed using the Palmer Drought Severity Index (PDSI), a commonly used drought index. At interannual time scales, for the majority of the land surface, ...
Response of the HadGEM2 Earth System Model to Future Greenhouse Gas Emissions Pathways to the Year 2300
Publisher: American Meteorological Society
Abstract: new ensemble of simulations from the Earth System configuration of the Hadley Centre Global Environmental Model, version 2 (HadGEM2-ES), is used to evaluate the response to historical and projected future greenhouse gas ...
Slippery Slopes: Gaining Traction in the Complex Process of Snow Model Intercomparison
Publisher: American Meteorological Society
Scientific and human errors in a snow model intercomparison
Publisher: American Meteorological Society
Abstract: The latest snow model intercomparison identified the same modelling issues as previous iterations over 23 years. Lack of new insights are attributed partly to human errors and intercomparison projects design.Twenty-seven ...
