The influence of synoptic conditions on interdiurnal atmospheric pressure changes in Poland.

Abstract

The aim of the presented study was to characterize the territory of Poland in terms of the frequency of occurrence of specific values of IAPC (interdiurnal atmospheric pressure changes) and to determine synoptic situations accompanying their particularly high values. The study is based on the daily mean atmospheric pressure data from the years 1966-2022 taking from 48 meteorological stations in Poland. In the presented paper four IAPC categories were used: A < 4.0 hPa (weak sense of change), B 4.1-8.0 (moderate sense of change), C 8.1-12.0 (strong sense of change), and D > 12.1 (very strong sense of change). Taking into account the negative impact on human health and well-being of the IAPC value, and especially its declines (conductive to the increase of suicides, heart and kidney diseases, asthma), the most unfavorable in this respect in Poland is the northern part of the country. The greatest frequency of synoptic situations causing the above-mentioned influence occurs in the cold half of the year, especially in winter. In turn the beneficial impact of the increase in IAPC on human health and well-being in terms of blood oxygenation and reduced suicide mortality caused by IAPC also occurs in the northern Poland. The frequency of synoptic situations felt in this respect is also highest in the cold half of the year.
