Abstract: The character of heating distribution near the front and the action of diabetic heating frontogenesis on the frontal maintenance and movement are estimated by using the objective data. It is indicated that the large-scale latent heat is distributed mainly along the front with band feature in the meridional vertical profile, and that the meso-scale character of frontal structure is given. According to the computation, the action of heating frontogenesis is important to frontal formation, maintenance and its movement. It is also shown that heating frontogenesis is unfavourable to the maintenance of horizontal stable layer in the quasi-stationary front
