    1. Unsaturated air parcels move along isentropic surfaces thus allowing a conceptually easy way to identify airstreams and to visualize regions of rising and sinking air. In this framework, a wind vector flowing toward lower pressure is ascending, and toward higher pressure is sinking. When latent heat is released during saturation, ascending air will be ascending faster (above the isentrope), but qualitatively the visualization still works as ascending air. by the condensation of moisture. The release of latent heat in an ascending saturated air parcel causes the parcel to leave the isentropic surface and to move upward with respect to the surface. 
    2. This works well most of the time, but be careful with rapidly developing systems or fast-moving cyclones, since this framework assumes negligible local pressure changes.
