Sensitivity Analysis of Different Convection Schemes and Center Domains for Numerical Simulation of Winter Precipitation Over Iran
This paper qualifies the effect of different convection schemes and center-domains on the simulation of winter precipitation over Iran using RegCM3 numerical climate model. It is compressible, finite difference with hydrostatic equilibrium in sigma coordinate with a semi-implicit algorithm for reduction of horizontal diffusion. Iran experienced two dry and wet periods during winters of 1997 and...
متن کاملMesoscale Motions Induced by Cumulus Convection : a Numerical Study
There is evidence from observations that evaporation of precipitation falling from widespread thick masses of middle-and high-cloud cumulonimbus debris is of vital importance to the dynamics of some tropical disturbances. A numerical model suitable for testing this idea has been designed and run. Dynamics of the large-scale flow are governed by the hydrostatic unfiltered equations specialized t...
متن کاملnumerical simulation on wind flow over step-shaped cliff topography with rough surface
to enhance the understanding of the impact of obstacle buildings on pollution transportationand dispersion in the atmospheric boundary layer, it is necessary to know the atmospheric flow characteristics over terrains. wind flow characteristics in a boundary layer over a step-shaped cliff topography model with rough and smooth surfaces were studied numerically using computational fluid dynamics ...

متن کاملNumerical Simulation of Nonpenetrative Turbulent Thermal Convection
Nonpenetrative convection Ð in which the lower boundary condition is one of constant heat flux and the upper boundary is insulatedÐ is an idealization of penetrative convection, which finds application in the planetary boundary layer. Three-dimensional, unsteady, ( ) direct numerical simulations 96 = 96 = 128 have been performed of turbulent, nonpene7 trative thermal convection inside a cubical...
