Connection between ENSO phenomena and solar and geomagnetic activity

Abstract

Abstract.Connections between El Niño -Southern Oscillation (ENSO) phenomena and indices of solar activity and geomagnetic disturbance were investigated. Spectral analysis of the ENSO-data was carried out. Oscillations with periods of about 11-12, 5-6, 2-3 years were found. Correlative and cross-spectral analysis was carried out to estimate connections between ENSO data, and solar and geomagnetic indices. Functions of coherency and phase were calculated.

Variability of rainfall and temperature (1912–2008) parameters measured from Santa Maria (29°41′S, 53°48′W) and their connections with ENSO and solar activity

“…Southern Oscillation and solar activity (Wang et al 2000;Nuzhdina, 2002;Haigh, 2003;Raspopov et al, 2004;Souza Echer et al, 2008Courtillot et al, 2010;Le Mouël et al, 2010).…”

Climate interaction mechanism between solar activity and terrestrial biota

“…Peaks shorter than 1 yr may be due to seasonal climatic phenomena. The ∼2 yrs period can be associated with the Quasi-Biennial Oscillation (QBO) in the stratosphere (Holton et al 1972;Dunkerton 1997;Baldwin et al 2001;Naujokat 1986;Holton et al 1980) and with the solar activity (Kane, 2005).The periodicities ∼3 and 4 yrs could be related to the El Niño-Southern Oscillation (ENSO) (Nuzhdina 2002;Njau 2006: Enfield 1992) that is a large-scale climatic phenomenon. The periodicities ∼5 yrs can be a harmonic of the 11-yrs solar cycle (Djurović & Páquet 1996).…”

Influence of circulation indices upon winter temperature variability in Egypt

“…Oscillations with different periods are identified. Short period oscillations with lengths ranging from 2 to 7 years are detected as well as long period oscillations ranging from 25 to 100 years (Nuzhdina, 2002). Fig.…”
