Abstract: In the 80- to 105-km height region, zonal winds and their vertical shears, as well as ionospheric drifts, show a semiannual variation that is in phase with a similar oscillation in temperature and density at satellite ...

Abstract: Interlevel correlations of the wind are shown to be quite stable over large areas of the Northern Hemisphere. Based on this fact, vertical correlation coefficients for 70 stations were categorized into three types, each ...

Abstract: Mean meridional cross-sections were constructed from the equator to the North Pole along 80°W, for January, April, July and October. The profiles of the zonal flow extend to 25-millibar heights (circa 26 kilometers). The ...

Abstract: Atmospheric motions from 54 sodium cloud firings are examined in the 80?200-km. height region. To gain an insight into various types of motion that are presumably present in the total observed wind, an oscillatory component ...

Abstract: This paper examines apparent ageostrophic deviations at 300 and 200 mb over the United States, their relationship to upper-air synoptic patterns, and the extent to which ageostrophic deviations affect wind forecasts made ...

Abstract: AbstractPresented here is a new dust modeling framework that uses a backward-Lagrangian particle dispersion model coupled with a dust emission model, both driven by meteorological data from the Weather Research and Forecasting ...

Abstract: This study investigates annual river basin–level water criticality (ratio of available water to withdrawals) considering effects of climate change on supply and of future population change on demand. A steady-state water ...
