Solar and geomagnetic activity effects on climate at regional and global scales: Case study—Romania

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

“…The search for possible influences of solar activity on the different meteorological or climatological parameters is one key element that has been widely used to prove the Sun-climate connection. The literature contains an extensive history of this issue (Rigozo et al, 2004;Valev, 2006;Kilcik et al, 2008;Dobrica et al, 2009;Souza Echer et al, 2009;Le Mouël et al, 2010). Despite the scientific works supporting the view that meteorological phenomena must respond to variations of solar activity, this subject is far from being settled (Tsiropoula, 2003;Lockwood and Frohlich, 2007).…”

The Effects of Space Weather on Hurricane Activity

“…Cook et al, 1997;Mendoza et al, 2005;Mendoza et al, 2006), Russian tree ring width (Raspopov et al, 2004), temperature records (e.g. Dobrica et al, 2008), tree ring width from Brazil and Chile (Rigozo et al, 2007), or total annual rainfall series in southern Brazil (Souza-Echer et al, 2008). Moreover, large-scale climatic phenomena such as the NAO, the AMO, the Pacific Decadal Oscillation or the Southern Oscillation, show quasi-bidecadal periodicities (e.g.…”

Cosmic rays and space weather: effects on global climate change

“…Haigh (1996), and Shindell et al (1999) suggested that the heating of the stratosphere by UV radiation can be dynamically transported into the troposphere. This effect might be responsible for small contributions towards 11 and 22 yr cycle modulation of climate but not to the 100 yr or more of climate changes that were observed in the past and during the last hundred years (Dobrica et al, 2009). Hong et al (2011) examined the effect of the 11-yr solar cycle and quasi-biennial oscillation on the 27-day solar rotational period detected in tropical convective cloud activity (it was analyzed data of outgoing long wave radiation for 1979-2004).…”
