Pressure maps show the expected air pressure at sea level for a day or a given time step in hPa with isobars. Sometimes an indication of a high or a low pressure area is shown with H or L respectively.
It is possible to combine the pressure maps with wind animation and the graticule by activating the different options in the lower right corner with one click.
Thickness / Pressure
The thickness / pressure map shows the thickness of the air layer between 1000 and 500 hPa in metres with the help of colours according to the thickness. The mean sea level pressure is shown in hPa with isobars.
