Abstract: A linearized two-dimensional model was used to study the formation of convective rolls in the prestorm stage and organized squall lines near the dryline in the Great Plains. With a strong virtual potential temperature ...

Abstract: The forward-central (forward in time, central differencing in space) scheme and the Dufort-Frankel scheme applied to the transient heat equation are discussed here. The Dufort-Frankel scheme is shown to be unable to damp ...

Abstract: A modified forward-backward scheme applied to the anelastic system is proposed. This modified scheme not only retains all the advantages of the conventional forward-backward scheme but also is more consistent with the ...

Abstract: The linear stability of penetrative convection is investigated for three different undisturbed temperature profiles, each characterized by a stable layer on the top: case A) a two-layer profile with constant but different ...

Abstract: This paper shows that in the linearized shallow-water equations, the numerical schemes can become weakly unstable for the 2?x wave in the C grid when the Courant number is 1 in the forward?backward scheme and 0.5 in the ...

Abstract: Linear stability analysis of cloud streets is investigated by including the latent heat and considering a few types of wind profiles. The release of latent heat follows the wave-CISK hypothesis. The results indicate that ...

Abstract: The nonlinear equations are applied to study the interactions between the sea breeze circulation and trapeze instability in low latitudes. The well-developed sea breeze circulation produced by the nonlinear model at coast ...

Abstract: The interactions between the sea breeze circulation and trapeze instability are investigated using a set of linearized equations. The results show that mesoscale waves associated with trapeze instability can be easily ...

Abstract: The level 3 turbulence closure model proposed by Mellor and Yamada (1974) is modified 1) to incorporate the formulations for the turbulence third-order moments and pressure terms proposed by Zeman and Lumley (1976) and 2) ...
