The paper presents a study of cloudiness having the typical structure: the anticyclone curvature of the cloud’s mass and a large quantity of cirrus clouds on the cloudiness’ border. The integrated analysis of conventional and satellite data has shown that this cloudiness structure is observed in synoptic situations of warm air advection. This cloudiness was localized in the northerly and northwesterly periphery of the anticyclone, in the trough of the cyclone, or in the diffuse pressure field, generally presented as lines of instability in synoptic maps. Sometimes, as a result of the warm advection, it is observed frontogenesis, cyclogenesis or the regeneration of the old cyclone. The satellite data enables the discrimination of warm air advection regions earlier (24-48 h) than the synoptic maps.
