Abstract: A simple method is developed for determining the unsteady state phreatic surface in earth dams as a function of time. The method is useful for the stability analysis of temporary dams where the steady state seepage condition ...

Abstract: The general nature of two-dimensional mixing on isentropic surfaces in the troposphere has been investigated. The daily time series of isentropic winds is obtained from a global general circulation model and is used to ...

Abstract: The authors have explored the factors governing upper-tropospheric relative humidity with a simple model based on isentropic mixing and condensation. Our analysis has focused on the Northern Hemisphere winter season and ...

Abstract: Although the phenomenon of equatorial quasi-biennial oscillation is relatively well understood, the problem of how the equatorially confined QBO wave forcing can induce a signal in the extratroics of comparable or larger ...

Abstract: Observational evidence for a global quasi-biennial oscillation (QBO) pattern is reviewed. In particular, the presence of an extratropical, as well as an equatorial, component of the QBO signal in column ozone is established. ...

Abstract: This paper documents our two-dimensional model which incorporates comprehensive radiative transfer and chemistry modules coupled with self-consistent dynamical transports. A simultaneous simulation of a range of chemical ...

Abstract: We perform a diagnostic study of Eliassen-Palm flux divergence (? · F), and isentropic mixing coefficient (Kyy) in the stratosphere for different seasons and for both hemispheres, taking into account nongeostrophic effects. ...

Abstract: A finite element method programmed for a computer is presented for determining the stresses and deflections in multiple slabs on elastic solids. The method is an extension to that presented in a previous paper by applying ...
