K. Labitzke, The global signal of the 11-year sunspot cycle in the stratosphere: Differences between solar maxima and minima, METEOROL Z, 10(2), 2001, pp. 83-90
Based on the data of 4 solar cycles, the global structure of the signal of
the Ii-year sunspot cycle (SSC) in the stratosphere and troposphere was exa
mined in earlier studies, using correlations between the solar cycle and he
ights and temperatures at different pressure levels. Here, this work is exp
anded to show the differences of geopotential heights and temperatures betw
een maxima and minima of the SSC. The global solar signal is shown and the
differences between the hemispheres are stressed. It is pointed out that du
ring the northern winter (January/February) the QBO modulates the global so
lar signal. This study puts the earlier work on a firmer ground and gives t
he community of modellers, who simulate the solar signal with GCMs, quantit
ative values for comparison.
