A Statistical Evaluation of the Predictive Abilities of Climatic Averages
Publisher: American Meteorological Society
Abstract: The predictive abilities of NOAA normals and running means of 2?30 years length are tested statistically. Heating degree-day (HDD) data from six northern United States sites are tested using root-mean-square error of ...
The Effect of Intraseasonal Circulation Variability on Winter Temperature Forecast Skill
Publisher: American Meteorological Society
Abstract: The prediction of winter in the United States from Pacific sea surface temperatures was examined using a jackknifed regression scheme and a measure of intraseasonal atmospheric circulation variability. Employing a jackknifed ...
Implications of the Recent Trend in the Arctic/North Atlantic Oscillation for the North Atlantic Thermohaline Circulation
Publisher: American Meteorological Society
Abstract: Most projections of greenhouse gas?induced climate change indicate a weakening of the thermohaline circulation (THC) in the North Atlantic in response to increased freshening and warming in the subpolar region. These changes ...
Intercomparison of the Southern Ocean Circulations in IPCC Coupled Model Control Simulations
Publisher: American Meteorological Society
Abstract: The analyses presented here focus on the Southern Ocean as simulated in a set of global coupled climate model control experiments conducted by several international climate modeling groups. Dominated by the Antarctic ...
CORRIGENDUM
Publisher: American Meteorological Society
Future Changes in Northern Hemisphere Snowfall
Publisher: American Meteorological Society
Abstract: sing simulations performed with 18 coupled atmosphere?ocean global climate models from phase 5 of the Coupled Model Intercomparison Project (CMIP5), projections of the Northern Hemisphere snowfall under the representative ...
The Southern Hemisphere Westerlies in a Warming World: Propping Open the Door to the Deep Ocean
Publisher: American Meteorological Society
Abstract: A coupled climate model with poleward-intensified westerly winds simulates significantly higher storage of heat and anthropogenic carbon dioxide by the Southern Ocean in the future when compared with the storage in a model ...
Some Pitfalls in Statistical Downscaling of Future Climate
Publisher: American Meteorological Society
Abstract: AbstractStatistical downscaling (SD) is commonly used to provide information for the assessment of climate change impacts. Using as input the output from large-scale dynamical climate models and observation-based data ...
Have Aerosols Caused the Observed Atlantic Multidecadal Variability?
Publisher: American Meteorological Society
Abstract: dentifying the prime drivers of the twentieth-century multidecadal variability in the Atlantic Ocean is crucial for predicting how the Atlantic will evolve in the coming decades and the resulting broad impacts on weather ...
GFDL's CM2 Global Coupled Climate Models. Part II: The Baseline Ocean Simulation
Publisher: American Meteorological Society
Abstract: The current generation of coupled climate models run at the Geophysical Fluid Dynamics Laboratory (GFDL) as part of the Climate Change Science Program contains ocean components that differ in almost every respect from those ...
