Covariability of Components of Poleward Atmospheric Energy Transports on Seasonal and Interannual Timescales
Publisher: American Meteorological Society
Abstract: Vertically integrated atmospheric energy and heat budgets are presented with a focus on the zonal mean transports and divergences of dry static energy, latent energy, their sum (the moist static energy), and the total ...
Seamless Poleward Atmospheric Energy Transports and Implications for the Hadley Circulation
Publisher: American Meteorological Society
Abstract: A detailed vertically integrated atmospheric heat and energy budget is presented along with estimated heat budgets at the surface and top-of-atmosphere for the subtropics. It is shown that the total energy transports are ...
Indices of El Niño Evolution
Publisher: American Meteorological Society
Abstract: To characterize the nature of El Niño?Southern Oscillation (ENSO), sea surface temperature (SST) anomalies in different regions of the Pacific have been used. An optimal characterization of both the distinct character and ...
A Pathological Problem with NCEP Reanalyses in the Stratosphere
Publisher: American Meteorological Society
Abstract: A pathological problem has been discovered in the NCEP reanalyses in the stratosphere. It is manifested most strongly as a two-delta vertical wave in the divergence of the wind field above steep topography especially where ...
Accuracy of Atmospheric Energy Budgets from Analyses
Publisher: American Meteorological Society
Abstract: Issues relevant to achieving an accuracy of better than 10 W m?2 on 250-km scales for monthly means in the atmospheric energy balance are explored from the standpoint of the formulation and computational procedures using ...
Interannual Variability of Patterns of Atmospheric Mass Distribution
Publisher: American Meteorological Society
Abstract: Using the 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) for 1958 to 2001, adjusted for bias over the southern oceans prior to 1979, an analysis is made of global patterns of monthly ...
The Global Monsoon as Seen through the Divergent Atmospheric Circulation
Publisher: American Meteorological Society
Abstract: A comprehensive description is given of the global monsoon as seen through the large-scale overturning in the atmosphere that changes with the seasons, and it provides a basis for delimiting the monsoon regions of the ...
Quality of Reanalyses in the Tropics
Publisher: American Meteorological Society
Abstract: Broad vertical layer-averaged temperatures from the microwave sounder unit (MSU) are used as a quasi-independent validation of temperature fields from the U.S. National Centers for Environmental Prediction?National Center ...
