Wind speeds near the surface are roughly proportional to the distance between isobars so closely packed isobars mean strong surface winds...

This display helps with the recognition of clouds of different layers, even when they overlap. Brighter colouring represents greater cloud cover. Cloud-free areas appear white while areas of full cloud cover at all levels appear dark grey (e.g. active fronts)...
