“…Responses to inferred J z changes of high altitude clouds are found all year: with Forbush decreases by Todd and Kniveton (2001); and with relativistic electrons by Kniveton and Tinsley (2004) and by Roldugin and Tinsley (2004). However effects on cyclones in the northern hemisphere are confined to winter (sections 2.3, 2.4, and 2.5).…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. ABSTRACT: We review recent research articles that present observations of the large-scale day-to-day dynamic tropospheric response to changes in the downward current density J z of the global atmospheric electric circuit (GEC). The evidence for the global circuit downward current density, J z , causing changes in atmospheric dynamics is now even stronger than as reviewed by Tinsley (Reports on Progress in Physics volume 71, 2008). We consider proposed mechanisms for these responses, and suggest future directions for research.

“…In particular, Tinsley et al (1994) suggest a mechanism that involves the global atmospheric electric circuit (AEC) and changes in relativistic electron precipitation linking the effects of charge accumulation to changes in ice nucleation. It has been shown that changes in the flux of precipitating relativistic electrons modulate the increased stratospheric resistivity due to the aerosols (Tinsley et al, 1994;Kirkland et al, 1996;Kniveton and Tinsley, 2004;Roldugin and Tinsley, 2004;. Resulting changes in current density J z affect space charge and there are several cloud microphysical processes that could respond to space charge.…”

The influence of solar wind on extratropical cyclones – Part 1: Wilcox effect revisited

2009

Abstract.A sun-weather correlation, namely the link between solar magnetic sector boundary passage (SBP) by the Earth and upper-level tropospheric vorticity area index (VAI), that was found by Wilcox et al. (1974) and shown to be statistically significant by Hines and Halevy (1977) is revisited. A minimum in the VAI one day after SBP followed by an increase a few days later was observed. Using the ECMWF ERA-40 re-analysis dataset for the original period from 1963 to 1973 and extending it to 2002, we have verified what has become known as the "Wilcox effect" for the Northern as well as the Southern Hemisphere winters. The effect persists through years of high and low volcanic aerosol loading except for the Northern Hemisphere at 500 mb, when the VAI minimum is weak during the low aerosol years after 1973, particularly for sector boundaries associated with south-to-north reversals of the interplanetary magnetic field (IMF) B Z component. The "disappearance" of the Wilcox effect was found previously by Tinsley et al. (1994) who suggested that enhanced stratospheric volcanic aerosols and changes in air-earth current density are necessary conditions for the effect. The present results indicate that the Wilcox effect does not require high aerosol loading to be detected. The results are corroborated by a correlation with coronal holes where the fast solar wind originates. Ground-based measurements of the green coronal emission line (Fe XIV, 530.3 nm) are used in the superposed epoch analysis keyed by the times of sector boundary passage to show a one-toone correspondence between the mean VAI variations and coronal holes. The VAI is modulated by high-speed solar wind streams with a delay of 1-2 days. The Fourier spectra of VAI time series show peaks at periods similar to those found in the solar corona and solar wind time series. In the modulation of VAI by solar wind the IMF B Z seems to conCorrespondence to: P. Prikryl (paul.prikryl@crc.ca) trol the phase of the Wilcox effect and the depth of the VAI minimum. The mean VAI response to SBP associated with the north-to-south reversal of B Z is leading by up to 2 days the mean VAI response to SBP associated with the south-tonorth reversal of B Z . For the latter, less geoeffective events, the VAI minimum deepens (with the above exception of the Northern Hemisphere low-aerosol 500-mb VAI) and the VAI maximum is delayed. The phase shift between the mean VAI responses obtained for these two subsets of SBP events may explain the reduced amplitude of the overall Wilcox effect.In a companion paper, Prikryl et al. (2009) propose a new mechanism to explain the Wilcox effect, namely that solarwind-generated auroral atmospheric gravity waves (AGWs) influence the growth of extratropical cyclones. It is also observed that severe extratropical storms, explosive cyclogenesis and significant sea level pressure deepenings of extratropical storms tend to occur within a few days of the arrival of high-speed solar wind. These observations are discussed in the context of the proposed AGW me...

“…Ions are involved in many atmospheric processes. In particular numerous studies suggest that ionisation due to CR may affect different climate parameters such as cloud cover (Pudovkin and Veretenenko 1995;Svensmark and Friis-Christensen 1997;Feynman and Ruzmaikin 1999;Marsh and Svensmark 2000;Pallé et al 2004;Usoskin et al 2004b;Harrison and Stephenson 2006;, precipitation (Stozhkov et al 1996;Kniveton and Todd 2001;Stozhkov 2003;Kniveton 2004), cyclogenesis in mid-to high-latitude regions (Tinsley et al 1989;Tinsley and Deen 1991;Pudovkin and Veretenenko 1996;Veretenenko and Thejll 2004), atmospheric transparency (Roldugin and Vashenyuk 1994;Veretenenko and Pudovkin 1997;Roldugin and Tinsley 2004), aerosol formation (Shumilov et al 1996;Mironova and Pudovkin 2005;Kazil et al 2006). Some investigations offer possible mechanisms responsible for the observed phenomena, such as the effect of the cosmic ray induced ionisation (CRII) on the global electric circuit (Tinsley and Zhou 2006;Tinsley et al 2007) or ion-induced nucleation (Svensmark et al 2007).…”

Cosmic Ray Induced Ion Production in the Atmosphere

et al. 2008

View full text Add to dashboard Cite

An overview is presented of basic results and recent developments in the field of cosmic ray induced ionisation in the atmosphere, including a general introduction to the mechanism of cosmic ray induced ion production. We summarize the results of direct and indirect measurements of the atmospheric ionisation with special emphasis to long-term variations. Models describing the ion production in the atmosphere are also overviewed together with detailed results of the full Monte-Carlo simulation of a cosmic ray induced atmospheric cascade. Finally, conclusions are drawn on the present state and further perspectives of measuring and modeling cosmic ray induced ionisation in the terrestrial atmosphere.
