| dc.description.abstract | The article analyses the interdiurnal changes of atmospheric pressure as biometeorological mechanical stimulus that exerts influence on the human organism. It is based in the study of the daily values of the atmospheric pressure recorded in the years 1951–2000 in the area of Poznań. The following classification of inter-diurnal pressure changes is used in the research: type a, when the change is lower than 1 hPa and is not felt by the human organism; type b, when the range of the change is 1–4 hPa and is felt by the human organism only to an insignificant degree; type c, the average; type d, significant (Kozłowska-Szczęsna et al. 1997). The area of study is the mutability of pressure change throughout the period of many years and finding out the patterns in these changes and the annual cycle of the average interdiurnal pressure changes and the particular stimuli. As far as the annual cycle of the interdiurnal pressure changes characterised by the occurrence of the greater changes in the colder part of the year and the smaller ones in the warmer part of the year is concerned, it has been studied by other authors, who point out that it constitutes the permanent feature of this meteorological element (Kozłowska-Szczęsna 1991; Fortuniak et al. 2000). The annual cycle has been an incentive to searching for bioclimatic seasons of the interdiunal pressure changes, which are marked out by the application of Ward procedure. The method has made it possible to take into account all types of pressure changes at a time. The average frequency of their occurrence in the period of five days, therefore a matrix of data embracing 73 pentads, each of which has four features (corresponding to the four types of pressure changes. The pentads, which have been properly grouped, create dendrite, on the basis of which the image of the annual structure of bioclimatic diurnal seasons of pressure change is made. The study shows that in the area of Poznań there are four bioclimatic seasons during the entire year and that they differ in terms of the influence on the human organism. The most significant influence in terms of the frequency of occurrence is the season D, which takes places in the coldest time of the year. The least influential is season A due the infrequency of days when significant pressure changes take place. Between these two seasons, two transition seasons, B and C, happen twice a year. | pl_PL |
