The results suggest that the local torrential rain occurred on 13 July 2007 can be attributed to the uplifting of southeast streams at lower levels forced by mountains,and the local convection occurred on 10 July 2007 was triggered by an ABL convergence line.

In this paper Monin-Obukhov similarity functions,embeded with local free convection,of surface layer in unstable atmosphere are obtained by using dimensional analysis,in view of turbulent generation and development, based on determinative factors of turbulent transport---turbulent dynamic energy and mixing length.

Influence of summer local circulation on the transportation of ozone from urban to the downwind area in Beijing

Many factors have impact on local circulation such as surface friction,topography,thermal forcing and so on.

Choosing global external analysis data(1°×1°) of NCEP and domestic data of upper and surface as preliminary field,and using relaxation toward boundary condition and vapor project of single ice phase,we simulate the influence of the complex terrain of Henan west mountain area on local circulation on Jun 19,2006 by using mesoscale numerical model MM5.
