According to the numerical change of isobar in the figure, the precipitation area is located near the trough of low pressure. Find a point in the most curved protruding part of each isobar near the precipitation area, and connect the points with dotted lines. This point is the position of the trough of low pressure, and this position is the position where the front is formed. It can be seen from the dense isobar in the precipitation area and close to the anticyclone center that the cold air mass is strong and the formed front is a cold front.
