POTENTIAL TEMPERATURE

The temperature is influenced by a lot of physical processes with a diurnal cycle (e.g. difference between valley and foreland). Heat island effects of big cities, etc. are represented in temperature measurements, too.

  • Positive deviation means: temperature of the station is higher than the surrounding stations.
  • Negative deviation means: temperature of the station is lower than the surrounding stations.

    The potential temperature is calculated with the following equation:





    with:


    Up to now only low level stations (0 m £ h £750 m) have been checked. T (emperatue) und p(ressure) are the measured values.
