Recent work correlating the 11-year solar cycle with atmospheric elements grouped according to the phase of the Quasi-Biennial Oscillation

Abstract

Atmospheric elements at all levels from the surface to the Middle Atmosphere show a probable association with the 11-year solar cycle in northern winter, which can be observed only if the data are grouped according to the phase of the Quasi-Biennial Oscillation. As the correlations are often of opposite sign in the East and West phase of the QBO, the correlation coefficients are mostly small when one uses as full time series of an atmospheric element. The spatial patterns of the correlations resemble well-known teleconnection patterns. The sparse data and short series on the Southern Hemisphere permit only a limited investigation. Good relationships are found in the antarctic stratosphere in spring and at sea level in winter.
