Abstract: The sources of high-frequency (?14 day) fluctuations in global atmospheric angular momentum (AAM) are investigated using several years of surface torque and AAM data. The midlatitude mountain torque associated with the ...

Abstract: Statistics concerning the budgets of angular momentum heat and water vapor over the Northern Hemisphere are computed by two different methods for the winter of 1976?77. The first method employs an objective analysis scheme ...

Abstract: The sensitivity of various zonal mean general circulation statistics to the choice of the averaging period used to define them is tested with upper-air data for the Northern Hemisphere taken from the NMC global analysis ...

Abstract: Modern atmospheric and geodetic datasets have demonstrated that changes in the axial component of the atmosphere's angular momentum and in the rotation rate of the solid earth are closely coupled on time scales of up to ...

Abstract: General circulation fields and statistics are derived for the months of January and July 1983 from different sets of daily global analyses produced by NMC. The two sets differ only in that one has been archived prior to ...

Abstract: The zonal-mean meridional transport of water vapor across the globe is evaluated using the National Centers for Environmental Prediction?National Center for Atmospheric Research (NCEP?NCAR) reanalysis for 1948?97. The shape ...

Abstract: A barotropic shallow-water model is used to study the large-scale sea level response to realistic barometric forcing at periods ranging from 1 day to 1 year. Results are presented from coarse resolution ?open? ocean ...

Abstract: Prompted by the need for forecasts of changes in the length of day on 1-10 day time scales, this paper examines the quality of predictions of a proxy variable, namely the atmosphere's relative angular momentum (M) made by ...

Abstract: Maps of the streamfunction field for the vertically integrated flux of water vapor over the Northern Hemisphere are presented for each of six annual periods. This approach reveals the existence of a broad-scale cellular ...

Abstract: The variability of annually averaged water vapor and water vapor transport fields over the Northern Hemisphere during the fifteen year period 1958?1973 is studied by means of empirical orthogonal function (EOF) analysis. ...
