Abstract: Two modified versions of Bott's forward-in-time, positive-definite numerical advection scheme are described. One version is a conservative flux form; the other is a nonconservative advective form. Both versions demonstrate ...

Abstract: Monotonicity constraints and gradient-preserving flux corrections employed by many advection algorithms used in atmospheric models make these algorithms nonlinear. Consequently, any relations among model variables transported ...

Abstract: Bulk cloud microphysics parameterizations typically employ time steps of a few tens of seconds. Although the computational burden of these parameterizations is acceptable for the 1-day mesoscale cloud simulations for which ...

Abstract: The production of ammonium sulfate by oxidation of dissolved sulfur dioxide in cloud droplets in a wave cloud situation, and the resulting enhancement of cloud condensation nuclei (CCN) released from the cloud on evaporation, ...

Abstract: Binary homogeneous nucleation of sulfuric acid and water vapor is thought to be the primary source of new particles in the marine atmosphere. The rate of binary homogeneous nucleation depends strongly on temperature and ...

Abstract: A model for airflow over mountainous terrain is presented. The equations for steady, two-dimensional, laminar inviscid flow, including pseudo-adiabatic latent heat release, are derived. Approximate solutions to the linearized ...

Abstract: Expressions are derived for the horizontal and vertical components of the wind, the temperature, and the mass of water vapor condensed when air flows over a long mountainous ridge. The growth of solid precipitation particles ...

Abstract: The current paradigm of developing and testing new aerosol process modules is haphazard and slow. Aerosol modules are often tested for short simulation periods using limited data so that their overall performance over a ...
