Karin Labitzke and Markus Kunze: Variability in the stratosphere: The sun and the QBO

Piers has pointed me to Labitzke’s work a few times.

Here’s a 2009 paper I missed at the time which shows the ‘top down’ modulation of seasonal weather by changes in solar activity. I think Ren and Stephen Wilde will like this one.



Large effects of solar variability related to the 11-year sunspot cycle (SSC) are seen in the stratosphere, but only if the data are grouped according to the phase of the QBO (Quasi-Biennial Oscillation). New results based on an extended, 66-year long data set fully confirm earlier findings and suggest a significant effect of the SSC on the occurrence of the Major Midwinter Warmings (MMWs) over the Arctic as well as on the strength of the stratospheric polar vortex and on the mean meridional circulation. By means of teleconnections the dynamical interaction between the Arctic and the Tropics in the stratosphere and in the troposphere is shown for the whole data set and compared with the anomalies…
