- Synopsis
- This page shows two diagrams of the causes of low air pressure, each 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. The diagram at the top of the page is a cross section view of a low pressure system and the one at the bottom is a map view of the same system (seen from above). Cross section: At the top of each side of the image are two clouds. There are two, curved lines of arrows starting close to the surface of the Earth at the centre of the page. These indicate cool air spiralling inwards into the clouds at the top right and left of the page. Between the lines of arrows is a single arrow that points upwards showing the lighter warm air rising. Map: The diagram at the bottom of the page shows the same weather system from above. The clouds have been omitted. There is a series of concentric isobars represented by heavy dashed lines; each one is marked with the air pressure. Four arrows curve anti-clockwise towards the area of lowest pressure in the middle of the diagram, representing cool air spiralling inwards at the surface of the Earth.
