The Space and Terrestrial Weather (Weather Complex) impact on ischemia cases in Saint Petersburg is investigated. The results show the main feature of the Weather Complex when it was related to the days of the different ischemia situations in the different ischemia people gender groups. The data treatment was done with some elements of the Folder Epochs Method, Cluster Analysis and the Mann–Whitney hypothesis test criterion.

Introduction. In recent years, the influence of climatic factors on population health has become particularly relevant. With significant fluctuations in meteorological conditions, there is an overstrain and failure of the adaptation. This leads to disorders of the functioning of the cardiovascular and central nervous systems. The purpose of the study is to assess the relationship of the population’s medical care with climatic factors, based on the available databases of indicators of Earth and space weather and data on the frequency of the population’s medical care. Material and Methods. For the analysis, we used a database of the population’s access to medical care and variations of climatic factors from 19.12.2005 to 31.12.2009 in the Kalininsky district of St. Petersburg. The total number of environmental parameters included in the study was 237, and the number of requests for medical care was 2.444. Results. In this paper, we tested a model for assessing the relationship between the population’s access to medical care and Earth and space weather factors. Gender and seasonal analysis were carried out. Time dependencies were studied. The obtained data allowed us to form a list of climate indicators that affect the health of the population. Conclusion. The most significant climatic indicators associated with coronary heart disease were identified. The most dangerous season of the year is autumn. Women have a higher sensitivity to changes in Earth and space weather than men. Accounting for variations in space weather allows predicting changes in medical treatment requests in 2-5 days, accounting for variations in the Earth’s weather - in 1 day.

<p>The main idea of our work is to find out the perspective points for the investigation of space factors which can impact physical and biological processes on Earth surface. Some decades ago the complex of those factors was named as “Space Weather”. So the main purpose of our work is to discover the connection between Space Weather and Terrestrial Weather as well as the impact of this environmental complex (Space Weather plus Terrestrial Weather) on biological objects and thereby on the human health.</p><p>The first part of the presented work contains the description of the Space Weather characteristics for the appearance moments of very long-live (more than 10 days) atmosphere pressure systems on different terrestrial latitude locations. These Long-live Pressure Systems (LPS) are interesting for us because some of them (namely anticyclones) can block pressure fields so they can create some dangerous situations for the human health as well as for the human activity. The different terrestrial latitude locations were: (1) Saint-Petersburg (59<sup>o</sup>57‘N, 30<sup>o</sup>19‘E) and (2) Tambov (52<sup>o</sup>43‘N, 41<sup>o</sup>27‘E). This latitude difference in observations is interesting for us because we know about the different affect of Space Weather variations on northern and southern places so we want to study this difference.  The time-intervals were: (1) 1999-2014 years (Saint-Petersburg), (2) 2007-2014 years (Tambov). Space Weather parameters were: (1) global  variations of Solar Activity (SA) parameters; (2) daily characteristics of the SA flare component in various bands of the electromagnetic spectrum; (3) variations of Interplanetary Space characteristics in Earth vicinity; (4) variations of daily statistics of Geomagnetic Field (GMF) characteristics. For the appearance moments of LPS we have discovered the interesting behaviour for follow Space Weather characteristics: variations of all global SA indices, variations of low energy (C-class) X-ray solar flares number, variations of proton fluxes, and variations of GMF parameters daily statistics. Also we have discovered the terrestrial-latitude difference in the atmosphere response on the Space Weather impact.</p><p>The second part of our work contains the results of investigation of environmental (Space Weather plus Terrestrial Weather) impact on human health. This study was done for Saint-Petersburg region (the northern place from the previous point of our investigation). The human health status was indicated by: (1) Cardiac Rhythm Variations (CRV) of patients in the clinic of Medicine Academy, Sudden Cardiac Deaths (SCD) in Research Institute of Emergency Medicine, facts of hard situation in 6 local clinics in different places of Saint-Petersburg and its suburb. We have found out that the dramatic cardiac events (CRV extrema, SCD maxima, hard days in clinics) are connected with variations of solar radio bursts number (the burst type is “noise storm”), the spread daily statistics (coefficient of variation) of GMF z-component and with spread daily statistics (coefficient of oscillation) of air temperature.</p><p>Results of our work may be used as the base for the hazard environmental monitoring.</p>

<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>
