| description | The global structure and the size of the signal of the 11-year sunspot cycle in the stratosphere and troposphere was examined in earlier studies. The correlations between the solar cycle and heights and temperatures of and at different pressure levels were mainly carried out with the whole data set and only during northern winters the years were separated according to the phase of the Quasi-Biennial Oscillation. Here, this work is expanded and it is shown that the Quasi-Biennial Oscillation must be introduced during northern summers, because the solar signal is very different in the respective phases of the Quasi-Biennial Oscillation, particularly over the tropics and subtropics. The structure of the solar signal in (northern) summer appears to indicate that the mean meridional circulations (Hadley and Brewer-Dobson Circulations) are influenced by the 11-year sunspot cycle, especially during the east phase of the Quasi-Biennial Oscillation. This result may help to find the mechanism through which the solar cycle (and the connected variation of the ultraviolet radiation) can influence the atmosphere. Die globale Struktur und die Größe des Signals des 11-jÄhrigen Sonnenfleckenzyklus in der Strato- und TroposphÄre wurde von uns in verschiedenen Arbeiten untersucht. Meist standen etwa vier Zyklen zur Verfügung. Bisher haben wir nur im Nordwinter die Quasi-Biennial Oscillation eingeführt, um das solare Signal zu finden, außerhalb dieser Saison benutzten wir fast immer den gesamten Datensatz, um die Anzahl der FÄlle groß zu lassen. In dieser Arbeit soll aber gezeigt werden, dass man die Quasi-Biennial Oscillation auch im Nordsommer einsetzen muss, weil das solare Signal auch außerhalb des Nordwinters in den verschiedenen Phasen der Quasi-Biennial Oscillation über den Tropen und Subtropen sehr unterschiedlich ist. Die Struktur des solaren Signals im Sommer deutet darauf hin, dass die mittleren Meridionalzirkulationen (Hadley und Brewer-Dobson Zirkulation) besonders wÄhrend der Ostphase der Quasi-Biennial Oscillation beeinflusst werden. Dieses Ergebnis soll helfen, den Mechanismus zu finden, durch den der 11-jÄhrige Sonnenfleckenzyklus und insbesondere die damit verbundenen Schwankungen der UV-Strahlung auf die AtmosphÄre wirken können. |
