Summary

A method for calculation of initial temperature in a coordinate models from pressure gradient force interpolated from constant pressure surfaces is discussed. Uniqueness of the solution is examined. It is demonstrated that there exists a possibility of obtaining two solutions. An approximative procedure for defining unique temperature is proposed. Advantages of the method are demonstrated using several examples. Amongst these, forecasts of a Genoa Gulf cyclogenesis are made with and without application of the proposed technique.

Zusammenfassung

Es wird eine Methode zur Berechnung der Ausgangstemperatur in a Koordinatenmodells aus der aus konstantem Bodendruck interpolierter Druckgradientkraft besprochen. Die Einzigartigkeit der Lösung wird untersucht. Es wird gezeigt, daß es eine Möglichkeit für zwei Lösungen gibt. Ein Näherungsverfahren zur Bestimmung eines einzigen Temperaturwertes wird vorgeschlagen. Vorteile dieser Methode werden an einigen Beispielen gezeigt. Dabei werden Vorhersagen für die Zyklonen im Golf von Genua mit und ohne Anwendung der vorgeschlagenen Methode durchgeführt.
