The “Wilcox effect” are important markers in the solar wind structure The solar wind magnetic sector boundaries that were used to observe Gravity waves (AGWs) could be a link between the solar wind and severe (2009b) suggested that auroral atmospheric

Northern and southern hemisphere winters using the European Center for The “Wilcox effect” was verified for both the (VAI) (Roberts and Olson, 1973), which can be considered as a proxy forĮxtratropical storminess. (1973, 1974,ġ975, and 1976) using the upper-level tropospheric vorticity area index Tropospheric vorticity was first suggested by Wilcox et al. The relation between the solar wind magnetic sector structure and These results indicate that vertical coupling in the atmosphere exertsĭownward control from solar wind to the lower atmospheric levels influencing tropospheric weather It is primarily the energy provided by release of latent heat Initiate convection to form cloud/precipitation bands. Troposphere, these gravity waves can provide a lift of unstable air to release instabilities in the troposphere and In spite of significantly reduced amplitudes but subject to amplification upon reflection in the upper Propagating waves originating in the lower thermosphere can excite a spectrum of gravity waves in the lowerĪtmosphere. Wave propagation in a model atmosphere using the Transfer Function Model (Mayr et al., 1990) reveal that Modulate Joule heating and/or Lorentz forcing of the high-latitude lower thermosphere generating medium-scaleĪtmospheric gravity waves that propagate upward and downward through the atmosphere. Leading edge of high-speed solar wind streams is a locus of large-amplitude magneto-hydrodynamic waves that Physical mechanism to explain these observations is proposed. Cases of severe weather events are examined in the context of the magnetosphereionosphere-atmosphere (MIA) coupling. Previously published statistical evidence that explosive extratropical cyclones in the northern hemisphere tend to occur within a few daysĪfter arrivals of high-speed solar wind streams from coronal holes (Prikryl et al., 2009, 2016) is corroborated for It is observed that significant snowfall, wind and heavy rain, particularly if causedīy low pressure systems in winter, tend to follow arrivals of high-speed solar wind.
