Summary
Three simple technique of incorporating the influence of moisture on potential temperature calculations are briefly discussed. These techniques lead to slightly differing values of potential temperature for a given sample of moist unsaturated air. It is shown that these small differences may be of importance in certain numerical modelling studies.
Zusammenfassung
Es werden drei einfache Methoden zur Berücksichtigung des Einflusses der Feuchtigkeit bei Berechnugen der potentiellen Temperatur kurz besprochen. Diese Methoden führen zu geringfügig unterschiedlichen Werten der potentiellen Temperatur bei einer gegebenen ungesättigten feuchten Luft. Es wird gezeigt, daß diese kleinen Unterschiede bei bestimmten numerischen Modellstudien von Bedeutung sein können.
