Formation of a depression: Stage 3 (Low) (large print)

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 shows an area of dotted texture to the top and left representing cool air, and an area of lined texture showing warm air in the bottom right. There are three heavy lines: one dashed and two with shapes along them. At the top of the diagram is the cold polar air. A short distance down the page, on the left, is a thick line with triangles and semicircles along it, which shows an occluded front. This line continues diagonally down to the right with only semicircles. This represents a warm front. Curving down from the centre of the diagram to the bottom left corner is a thick line with triangles along it, showing a cold front. In the centre of the page, horizontally crossing both the cold and warm fronts is a thick dashed line marked A on the left and B on the right. This shows the position of the cross section. 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 shows 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, the one on the right goes diagonally right. Just up from the ground and to the left and right 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 above the ground is an area of warm air. A dotted arrow up the page, points up the page, shows the movement of warm air up the page. To the left and right of the two fronts is an area of cool air.
