Formation of a Depression: Stage 2 (Low) (tactile)

Synopsis

On this page there are two labelled diagrams showing the formation of a depression, both with a dashed line image border. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. To the left of the page is a map of the formation of a depression and to the right is a cross section view. Map: This diagram has an area of dotted texture at the top representing cool air, three heavy lines in the middle, one dashed, one with triangles along its length and one with semicircles. At the bottom of the page the lined texture represents warm air. At the top is the cool air with four arrows curving round in a counterclockwise direction showing the direction of movement of the air. Further down on the left is a thick dashed line, marked A on the left and B on the right, which shows the position of the cross section view. On the left this line passes through a cold front, shown as a curved line with triangles along it, and on the right a warm front, shown as a line with filled semicircles along it. Down the page from these is an area of warmer air. Cross section: The cross section (a view from the side) on the right of the page shows the same event. This diagram has a large area of dotted texture representing cold air with a smaller area of lined texture, representing warm air, in the centre. The fine textured area at the bottom represents the ground. Two heavy lines with shapes along them go up the page. At the bottom is a thick dashed line with the left end marked A and the right B. It equates with the thick dashed line on the map view. Up from this is the ground. Two thick lines go up the page from this. The one on the left curves up to the left; it has a series of triangles on it and represents a cold front. The one on the right goes diagonally right; it has a series of semicircles along it and represents a warm front. Just up from the ground and to the left and right of the two fronts are two arrows; the one on the left points to the right and the one on the right points left. These show the direction of cool air movement. Between the two fronts and just up the page from the ground is a small area of warm air. Two dotted arrows pointing up the page show the movement of warm air. To the left and right of the two fronts is an area of cool air.
