In this paper, based on the system of equations quantitatively describing the equilibyium model, with consideration of latent heat and frictional stress, and assuming rmonics, for the horizontal distribution of the field take the form of the approximate analytical solutions of vertical velocity and vorticity tendency on the standard level were obtained. The solutions were a set of linear polynomial in which all the term of thermal advection and vorticity advection were included, the values of these coefficients in the polynomial demonstrated the effect of these advection term on the vertcal velocity or vortcity tendency respectively. The coefficient were calculated for several standard cases. These might be help to explore qualitatively the main physical process of the development of synoptical and subsynoptical scale systems.

The compact high-performance plate-fin type heat exchangers have widely used in many industry areas. To provid the basic designing data, seven fin surfaces, including three fin types (strip--fin, perforated fin and plane straight fin), have been tested. The experimental characteristic curves are presented in terms of heat transfer factor j and friction factor f versus Reynolds number Re. The performance evaluation and comparison for the experimental fin surfaces has taken by the performance ranking method of plate-fin surfaces reported by Soland et al. In this paper the methods for further improving performance of fin surfaces also are discussed.
