Modifying the equation of potential temperature, two methods of computing vertical velocities are obtained. One of them is the single-station method using the data of pibal and sonde for a single aerological station only, and the other is the several-station method using the data of sonde for several stations. After making nomograms for simplicity in computations, the former method is applied in the case of cold front.
