The Space Weather events those accompany the long-lived macrosynoptic processes

<p>The presented work evolves the study of the Space Weather state before and during the macrosynoptic processes movements in North Atlantic and Eurasia extratropical latitudes. The atmosphere circulation types – E-type (east transport), W-type (west transport) and C-type (meridional transport) – were investigated by their periods of the conservation:  (5-7) days which corresponds to the Natural Synoptic Period (NSP) in Europe region and the Long Period (LP) which endured more than 10 days.</p><p>The investigation time interval: 1.01.2007 – 1.01.2014. That corresponds to: the Solar Activity (SA) 23-d cycle's fall branch, the SA minimum, the rise branch of the 24-th SA cycle, the maximum of 24-th SA cycle.</p><p>Space Weather parameters were: global  variations of SA parameters; daily characteristics of the SA flare component in various bands of the electromagnetic spectrum; variations of daily statistics of Interplanetary Space characteristics in the near-Earth space; variations of daily statistics of Geomagnetic Field characteristics.</p><p>Results:</p><p>1. LP-E-type occurs 56% of all LP when LP-W-type occurs 36% and LP-C-type occurs 8%.</p><p>2. The concrete Space Weather parameters which behavior differences the moments of LP-beginnings from the moments of NSP-beginnings for the E-type circulation (here we are presenting only results for the most frequent macrosynoptic type) are follows:</p><ul><li>All daily indexes of SA global variations – the integral solar radioflux on the wavelength of 10.7cm, the solar spot number, the summarized spot area on the solar disk, the number of new Active Regions on the solar disk.</li> <li>The daily statistics (maximum, mean, range, standard deviation) of α-particle fluxes with the energy of 4-10 MeV. </li> <li>The daily statistics (maximum, mean, range, standard deviation) of electron <sup></sup>fluxes of energy that is greater than 2 MeV. </li> <li>The daily statistics (maximum, mean, range, standard deviation) of the intensity of the whole magnetic field vector in the near-Earth space.</li> <li>The daily statistics (maximum, mean, range, standard deviation) of the intensity of the geomagnetic field that was measured at different terrestrial latitudes.</li> </ul><p>3. The most prominent events we can see in the behavior of the α-particle fluxes and in the behavior of the whole magnetic field vector in the near-Earth space those went on the background of the significant changing of global SA-indexes.</p><p>We suppose the complex impact the mentioned above Space Weather characteristics on the terrestrial atmosphere.</p><p>Results may be useful for the forecast of atmosphere response to the space impact.</p>
