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 study. If 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 occur. Our work points out that initial density distribution greatly influences the frontal features. If the stratification in cold air is the same as that in warm air, two frontogeneses will occur at top and bottom boundaries respectively.
