In earlier studies we examined the global structure and the size
of the signal of the 11-year sunspot cycle (SSC) in the
stratosphere and troposphere. We used for the correlations between
the solar cycle and heights and temperatures at different pressure
levels mainly the whole data set and only during northern winters
the years were stratified according to the phase of the
Quasi-Biennial Oscillation (QBO).
This work is expanded here and it is shown that the QBO
must be introduced throughout the year, because the solar signal
is very different in the respective phases of the QBO,
particularly over the tropics and subtropics.
The structure of the solar signal appears to indicate
that the mean meridional circulation systems (Hadley and
Brewer-Dobson Circulation) are influenced by the SSC, and stronger
so during the east phase of the QBO.
