The Role of Coupled Sea Surface Temperatures in the Simulation of the Tropical Intraseasonal Oscillation
Publisher: American Meteorological Society
Abstract: This study compares the tropical intraseasonal oscillation (TISO) variability in the Geophysical Fluid Dynamics Laboratory (GFDL) coupled general circulation model (CGCM) and the stand-alone atmospheric general circulation ...
Variational Objective Analysis for Atmospheric Field Programs: A Model Assessment
Publisher: American Meteorological Society
Abstract: The objective of this study is to examine the effectiveness of the variational objective analysis (VOA) for producing realistic diagnoses of atmospheric field program data. Simulations from the Naval Research Laboratory's ...
Potential Predictability of the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: The objective of this study is to estimate the limit of dynamical predictability of the Madden?Julian oscillation (MJO).Ensembles of ?twin? predictability experiments were carried out with the NASA Goddard Laboratory for ...
Bayesian Model Averaging of Climate Model Projections Constrained by Precipitation Observations over the Contiguous United States
Publisher: American Meteorological Society
Abstract: This study utilizes Bayesian model averaging (BMA) as a framework to constrain the spread of uncertainty in climate projections of precipitation over the contiguous United States (CONUS). We use a subset of historical model ...
Characterizing and Understanding Cloud Ice and Radiation Budget Biases in Global Climate Models and Reanalysis
Publisher: American Meteorological Society
Abstract: he authors present an observationally based evaluation of the vertically resolved cloud ice water content (CIWC) and vertically integrated cloud ice water path (CIWP) as well as radiative shortwave flux downward at the ...
Estimating the Satellite Equatorial Crossing Time Biases in the Daily, Global Outgoing Longwave Radiation Dataset
Publisher: American Meteorological Society
Abstract: Due to its long record length (approximately 25 years), the outgoing longwave radiation (OLR) dataset has been used in a multitude of climatological studies including studies on tropical circulation and convection, the El ...
The Vertical Structure of Radiative Heating Rates: A Multimodel Evaluation Using A-Train Satellite Observations
Publisher: American Meteorological Society
Abstract: We assess the vertical distribution of radiative heating rates (RHRs) in climate models using a multimodel experiment and A-Train satellite observations, for the first time. As RHRs rely on the representation of cloud ...
Intercomparison of Atmospheric GCM Simulated Anomalies Associated with the 1997/98 El Niño
Publisher: American Meteorological Society
Abstract: The atmospheric anomalies for the 1997/98 El Niño?Southern Oscillation (ENSO) period have been analyzed and intercompared using the data simulated by the atmospheric general circulation models (GCMs) of 11 groups participating ...
