主　　题：mesoscale weather geostrophic adjustment frontogenesis 

摘      要：A uniform,inviscid,incompressible fluid in a two-dimensional plane(x,z)is considered. Three principles:conservation of potential vorticity,conservation of absolute momentum,and conservation of mass are used for this *** the initial mass field and the initial wind field do not satisfy geostrophic balance,then through geostrophic adjustment under suitable conditions, the frontogenesis will finally *** work points out that the initial density distribution greatly influences the frontal *** the stratification in cold air is the same as that in warm air,two frontogeneses will occur at top and bottom boundaries *** the stratification in cold air is larger than that in warm air,the frontogenesis at the bottom boundary still exists,but the other at the top boundary *** result makes us further understand the mechanism of the frontogenesis in the real atmosphere.
