Dynamics of Steady Convections Over Heat and Cool Islands

This paper concerns with properties of a thermal convection in a stably stratified Boussinesq fluid caused by partial heating or cooling of the lower boundary. For infinitesimal heating (cooling) the

Large-Eddy Simulation of Mesoscale Circulations Forced by Inhomogeneous Urban Heat Island

The large-eddy simulation mode of the Weather Research and Forecasting model is employed to simulate the planetary boundary-layer characteristics and mesoscale circulations forced by an ideal urban

Preconditioned Conjugate-Residual Solvers for Helmholtz Equations in Nonhydrostatic Models

TLDR
The authors present an accurate and efficient technique for solving the Helmholtz equation using a conjugate-residual (CR) algorithm that is accelerated by ADI preconditioners and proposes a formulation that is more consistent than those most often used in that it includes implicit treatment of all terms associated with the pressure gradients and divergence.

A Benchmark Simulation for Moist Nonhydrostatic Numerical Models

A benchmark solution that facilitates testing the accuracy, efficiency, and efficacy of moist nonhydrostatic numerical model formulations and assumptions is presented. The solution is created from a

Abstract A large-eddy-simulation (LFS) model explicitly calculates the large-eddy field and parameterizes the small eddies. The large eddies in the atmospheric boundary layer are believed to be much

Application of the Piecewise Parabolic Method (PPM) to meteorological modeling

Abstract The Piecewise Parabolic Method (PPM), a numerical technique developed in astrophysics for modeling fluid flows with strong shocks and discontinuities is adapted for treating sharp gradients

Conservative Split-Explicit Time Integration Methods for the Compressible Nonhydrostatic Equations

Historically, time-split schemes for numerically integrating the nonhydrostatic compressible equations of motion have not formally conserved mass and other first-order flux quantities. In this paper,

Predictability of Dry Convective Boundary Layers: An LES Study

AbstractThe predictability horizon of convective boundary layers is investigated in this study. Large-eddy simulation (LES) and direct numerical simulation (DNS) techniques are employed to probe the

A three‐dimensional numerical investigation of the idealized planetary boundary layer

Abstract The nonlinear equations of motion are integrated numerically in time for a region of x‐y‐z space of volume 3h × h × h, where h turns out to be a height slightly above the level where the
