Abstract: A three-dimensional second-order closure meteorological and pollutant dispersion model is developed, and the computed results are evaluated. A finite-element method is used to solve the governing equations because of its ...

Abstract: A three-dimensional mesoscale meteorological model was developed based on second-moment closure equations that were solved by the finite-element method. This paper aims to evaluate the performance of the model under flat ...

Abstract: During 13 nights of Rayleigh lidar measurements at Urbana Illinois in 1984?86, thirty-six quasi-monochromatic gravity waves were observed in the 35?50 km altitude region of the stratosphere. The characteristics of the waves ...

Abstract: A novel extension of the spaced antenna method for VHF/UHF radar and wind profiler applications is introduced in this paper. It is proposed that instead of pointing the spaced antenna beams vertically, off-vertical oblique ...
