Abstract: Advective transport using the flexible and stable semi-Lagrangian scheme coupled with the highly accurate spectral interpolation in a limited domain is demonstrated. The spectral method for solving nonperiodic boundary ...

Abstract: Simple and efficient formulas for calculating surface fluxes are presented for the nondimensional profile functional forms of wind and temperature in the atmospheric surface layer. Four formulations representing nondimensional ...

Abstract: A semi-Lagrangian model was developed based on the atmospheric transport-diffusion equation, employing the semi-Lagrangian technique incorporated with the spectral method. The numerical algorithms of the semi-Lagrangian ...

Abstract: A pseudospectral method and its numerical solution algorithm for application to boundary layer problems in the atmosphere are presented. The method introduces the evaluation of a polynomial function when the solution is ...

Abstract: A dynamic turbulent boundary-layer model in the neutral atmosphere is constructed, using a dynamic turbulent equation of the eddy viscosity coefficient for momentum derived from the relationship among the turbulent dissipation ...

Abstract: An analysis of the linear and nonlinear interactions of atmospheric motion in the wavenumber-frequency domain indicates that the kinetic energy of the large-scale moving waves is essentially maintained by the nonlinear ...

Abstract: Vertical profiles of 222Rn concentrations measured from 3 to 6 September 1995 in the northeastern United States, using a new radon instrument designed for aircraft measurements, are presented. A vertical diffusion model ...

Abstract: Statistical models for surface-wind predictions at a mountain and a valley station near Anderson Creek, California, have been constructed. It is found that the surface wind speed depends primarily on the slope wind, ...
