Summary

Global fluctuations in the mean temperature of three stratospheric layers (10–30 mb, 30–50 mb. 50–100mb) were examined for the period 1957–1972. These data show that during the last decade of the analysis the mid layer (30–50 mb) cooled at a rate which is similar to the cooling rate observed in the lower troposphere. Hemispheric averages of the trend calculated for each layer show a net warming trend in the upper (10–30 mb) layer and the lower (50–100 mb) layer that is only one third or one half the cooling rate of the 30 50 mb layer. These same hemispheric trends appear when the analysis is restricted to the period after 1965, for which both observational data and analyses are more complete.

Klimaschwankungen in der Stratosphäre der Nordhemisphäre

Zusammenfassung

Es werden globale Schwankungen der Mitteltemperatur von drei Stratosphärenschichten (10–30 mb, 30–50 mb, 50–100 mb) in der Periode 1957 bis 1972 untersucht. Diese Daten ergeben, daß während der letzten Dekade der Analyse die mittlere Schicht (30–50 mb) um einen Betrag, der dem in der unteren Troposphäre beobachteten Abkühlungsbetrag ähnlich ist, abgekühlt ist. Die Hemisphärenmittel des für jede Schicht berechneten Trends zeigen eine Erwärmungstendenz in der oberen (10–30 mb) und in der unteren (50–100 mb) Schicht, die ungefähr ein Drittel oder halb so groß ist, wie der Abkühlungsbetrag in der Schicht 30–50 mb. Die gleichen hemisphärischen Tendenzen ergeben sich auch bei einer Beschränkung der Analyse auf die Periode nach 1965, in der die Beobachtungsdaten und die Analysen vollständiger sind.
