RISVertical Moist Thermodynamic Structure and Spatial–Temporal Evolution of the MJO in AIRS Observations
Publisher: American Meteorological Society
Abstract: The atmospheric moisture and temperature profiles from the Atmospheric Infrared Sounder (AIRS)/Advanced Microwave Sounding Unit on the NASA Aqua mission, in combination with the precipitation from the Tropical Rainfall ...
Nonstationary Synchronization of Equatorial QBO with SAO in Observations and a Model
Publisher: American Meteorological Society
Abstract: It has often been suggested that the period of the quasi-biennial oscillation (QBO) has a tendency to synchronize with the semiannual oscillation (SAO). Apparently the synchronization is better the higher up the observation ...
Influence of Doubled CO2 on Ozone via Changes in the Brewer–Dobson Circulation
Publisher: American Meteorological Society
Abstract: In this short note, the effect of enhanced circulation due to doubling CO2 on ozone is investigated. The difference of Brewer?Dobson circulation (BDC) between the doubled CO2 and control run from an idealized atmospheric ...
Modulation of the Period of the Quasi-Biennial Oscillation by the Solar Cycle
Publisher: American Meteorological Society
Abstract: The authors examine the mechanism of solar cycle modulation of the Quasi-Biennial Oscillation (QBO) period using the Two-and-a-Half-Dimensional Interactive Isentropic Research (THINAIR) model. Previous model results (using ...
Influence of Stratospheric Sudden Warming on AIRS Midtropospheric CO2
Publisher: American Meteorological Society
Abstract: idtropospheric CO2 retrievals from the Atmospheric Infrared Sounder (AIRS) were used to explore the influence of stratospheric sudden warming (SSW) on CO2 in the middle to upper troposphere. To choose the SSW events that ...
The Mechanical Energies of the Global Atmosphere in El Niño and La Niña Years
Publisher: American Meteorological Society
Abstract: wo meteorological reanalysis datasets are analyzed to determine the mechanical energies of the global atmosphere in the El Niño and La Niña years. The general consistency of the mean energy components between the two ...
Transient Climate Response in Coupled Atmospheric–Ocean General Circulation Models
Publisher: American Meteorological Society
Abstract: he equilibrium climate sensitivity (ECS) has a large uncertainty range among models participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) and has recently been presented as ...
Modulation of Midtropospheric CO2 by the South Atlantic Walker Circulation
Publisher: American Meteorological Society
Abstract: idtropospheric CO2 data from the Atmospheric Infrared Sounder (AIRS) are used in this study to explore the variability of CO2 over the South Atlantic Ocean. It was found that the area-averaged CO2 over the South Atlantic ...
Impact of Climate Drift on Twenty-First-Century Projection in a Coupled Atmospheric–Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: educing climate drift in coupled atmosphere?ocean general circulation models (AOGCMs) usually requires 1000?2000 years of spinup, which has not been practical for every modeling group to do. For the purpose of evaluating ...
Vertical Moist Thermodynamic Structure of the Madden–Julian Oscillation in Atmospheric Infrared Sounder Retrievals: An Update and a Comparison to ECMWF Interim Re-Analysis
Publisher: American Meteorological Society
Abstract: The large-scale vertical moist thermodynamic structure of the Madden?Julian oscillation (MJO) was documented using the first 2.5 yr (2002?05) of version 4 atmospheric specific humidity and temperature profiles from the ...
