RISTransient Eddy Forcing of the Rotational Flow during Northern Winter
Publisher: American Meteorological Society
Abstract: The total direct transient eddy forcing of the vorticity balance in the upper troposphere during northern winter is examined using 11 years of 2 to 8-day bandpassed global analyses. Most examinations of the importance of ...
Relationship between Tropical Heating and Subtropical Westerly Maxima in the Southern Hemisphere during SOP-1, FGGE
Publisher: American Meteorological Society
Abstract: FGGE Level III-b analyses, produced by the Goddard Laboratory for Atmospheres, NASA, are used to investigate the relationship between tropical heating and subtropical westerly maxima in the Southern Hemisphere during SOP-1 ...
An Evaluation of Monthly Mean MSU and ECMWF Global Atmospheric Temperatures for Monitoring Climate
Publisher: American Meteorological Society
Abstract: Monthly mean brightness temperature anomalies derived from channel 2 of the microwave sounding units (M5Us) on board NOAA satellites over the past decade are examined and compared with both weighted and pressure-level ECMWF ...
Difficulties in Obtaining Reliable Temperature Trends: Reconciling the Surface and Satellite Microwave Sounding Unit Records
Publisher: American Meteorological Society
Abstract: A chronic difficulty in obtaining reliable climate records from satellites has been changes in instruments, platforms, equator-crossing times, and algorithms. The microwave sounding unit (MSU) tropospheric temperature ...
Satellite versus Surface Estimates of Air Temperature since 1979
Publisher: American Meteorological Society
Abstract: A comparison of near-global monthly mean surface temperature anomalies to those of global Microwave Sounding Unit (MSU) 2R temperatures for 1979?95 reveals differences in global annual mean trends that are shown to be ...
Significance of the South Pacific Convergence Zone (SPCZ) in the Energy Budget of the Southern Hemisphere Tropics
Publisher: American Meteorological Society
Abstract: A modified set of FGGE Level III-b gridpoint analyses, originally produced by ECMWF, is used to diagnose the eddy energy budgets of four equal-area regions within the tropical Southern Hemisphere (0?30°S) during the SOP-1 ...
Global Sea Surface Temperature Analyses: Multiple Problemsand Their Implications for Climate Analysis, Modeling, and Reanalysis
Publisher: American Meteorological Society
Abstract: A comprehensive comparison is made among four sea surface temperature (SST) datasets: the optimum interpolation (OI) and the empirical orthogonal function reconstructed SST analyses from the National Centers for Environmental ...
On the Maintenance of Short-Term Subtropical Wind Maxima in the Southern Hemisphere during SOP-1, FGGF
Publisher: American Meteorological Society
Abstract: The extent to which divergent circulations, induced by tropical heating, help to maintain westerly maxima in the Southern Hemisphere subtropics during the SOP-1 of FGGE is explored using Level Bib analyses from the Goddard ...
A Comparison of the Atmospheric Circulations Simulated by the CCM3 and CSM1
Publisher: American Meteorological Society
Abstract: The atmospheric state simulated by the National Center for Atmospheric Research (NCAR) Community Climate Model, version 3 (CCM3), is compared to that simulated by the NCAR Climate System Model, version 1 (CSM1). CCM3 is ...
Conservation of Mass in Three Dimensions in Global Analyses
Publisher: American Meteorological Society
Abstract: For a number of reasons, conservation of mass in the global analyses on pressure coordinates is violated, yet this constraint is required for budget studies of all kinds. The imbalances arise from postprocessing the variables ...
