Abstract

Abstract The 12-month running mean series of atmospheric CO 2 directly measured at Mauna Loa, Hawaii, showed highly significant periodicities near T = 14, 8, 5, 3–4 years. This CO 2 series also showed a significant oscillation at T = 2.56 years which matches with T = 2.6 years of the Southern Oscillation (SO) index but not with the QBO ( T = 2.33 and 2.68 years) of the stratospheric zonal wind. On the other hand, the yearly range (maximum minus minimum) series of CO 2 showed periodicities T = 2.45 and 2.75 years (significant at the 2 sigma level) which seem similar to those of the stratospheric wind QBO ( T = 2.33 and 2.68 years). No evidence was found for a 11 year (solar cycle) component.
