     By using binary principle with the product of mesoscale model MM5, We diagnose the CSI in the rainstorm on Jun 29, 2003.Evidence suggests that CSI areas appear above the troposphere middle level in this rainstorm, and there were good relationships between the CSI areas and the strong precipitation under the condition of convective stability atmosphere;

  convective stability
The effect of induced magnetic fields on convective stability of a conductive liquid carrying a current
      
Convective stability in a spherical layer at rest, in a central gravity field, was first discussed in [1, 2].
      
As in the plane case, the problem of the convective stability of a spherical layer is found to be degenerate, and the form of the critical perturbations cannot be determined from the linear problem.
      
In [3] a study was made of the convective stability of a liquid in a slowly rotating thin spherical layer.
      
In the present work a study is made of the convective stability of a flow of liquid, arising in a rotating spherical layer due to a nonuniform distribution of the temperatures at one of the boundaries of the layer.

This paper is concerned with a study on Double-Diffusive Convection by an energy method. The convection is induced by buoyancy effects resulting from lateral heating of a vertical soluje gradient in a saturated porous medium contained between two infinite vertical plates. The stability of such a time-dependent flow is treated with linear perturbation method by distributing small random disturbances of given vertical wave-length throughout the fluid. The growth or decay of the kinetic energy of the perturbation...

This paper is concerned with a study on Double-Diffusive Convection by an energy method. The convection is induced by buoyancy effects resulting from lateral heating of a vertical soluje gradient in a saturated porous medium contained between two infinite vertical plates. The stability of such a time-dependent flow is treated with linear perturbation method by distributing small random disturbances of given vertical wave-length throughout the fluid. The growth or decay of the kinetic energy of the perturbation delineates the unstable and stable states. Results were obtained for a wide range of the salinity Rayleigh number Rs . Some interesting features of Double-Diffusive Stability were observed in the numerical experiment.

This paper is an experimental study of thermal convective stabilityin a vertical porous layer provided the lateral temperature gradient.Based on earlier investigations of Gill, the convective motion wassteady and unicellular. In fact, a pattern of horizontal vortices wasobserved. A rather detailed experimental investigation was carried outto study the instability phenomennon. Experimental results showedthat the presence of the secondary horizontal vorticities (secondarycell flow) and the stability of convection in the porous layer isconditioned. The presence of inertia effect in a vertical layer of water-saturated porous medium may have been effective.

本文用试验方法研究多孔介质中,流体在均匀侧向温度差作用下的热对流稳定性问题。通过对流场的实测和观察,发现横向层状二次流是存在的,这表明流场的稳定是有条件的。在多孔介质中,有时也不能忽视流体惯性效应的影响,这与Gill对此问题的理论分析结果是不同的。

A experimental investigation on the stability of thermal convection in a sloping porous Medium under lateral heating is reported.The investigation is performed for cases with large d/ L ratio where d is the average diameter of porous medium and L the thickness of porous layer. The results obtained show that there exists boundary effect near the solid walls of the test tank and that they are found to be different from those stable solutions obtained by omitting the inertial terms.It is also shown that the stability...

A experimental investigation on the stability of thermal convection in a sloping porous Medium under lateral heating is reported.The investigation is performed for cases with large d/ L ratio where d is the average diameter of porous medium and L the thickness of porous layer. The results obtained show that there exists boundary effect near the solid walls of the test tank and that they are found to be different from those stable solutions obtained by omitting the inertial terms.It is also shown that the stability of natural convection is dependent on the slope of the porous layer.

本文就含水的倾斜多孔介质层在侧向加热条件下流体热对流稳定性问题进行试验研究.试验在较大的粒径比条件下进行,再现了固体边壁对流场的影响.这与由忽略惯性项所建立的方程组导出的结果有所不同.试验还表明自然对流稳定性与多孔介质层壁间的倾角有关.
