Information

In addition to the standard variables some less common ones are included in the forecast.

Thickness

Thickness is the height of the 1000-500 hPa layer above sea level. It is a good indicator of how cold the air is. The lower the thickness the colder the air. 528 dam or lower is often an indicator of snow. 564 dam or higher can indicate heat wave conditions in the summer.

850 hPa

The air temperature at the 850 millibar pressure level in the atmosphere, which is located approximately 1.5 kilometers. It helps to distinguish between warm and cold air masses because it is not subject to day to night variations.

0°C level

The freezing level is the altitude in metres at which the air temperature is at 0°C

High, mid and low cloud

The percentage cloud cover at high, mid and low altitudes.
