Multiannual variability of the North Atlantic pressure and temperature, imposed by the lower stratospheric ozone
Analyses of the Northern Hemisphere’s sea level pressure, air surface temperature and lower stratospheric ozone, during the period 1900-2019, reveal an existing coherence in their temporal variability. The coherence is heterogeneously distributed over the globe, and the patterns of ozone impact on the pressure and temperature are different. More specifically, the strongest ozone influence on the sea level pressure is found in the main “centres of action” – i.e. the Aleutian low and the region of NAO formation. The ozone influence is localised mainly in the latitudinal belt 40-75 0N, where the ozone mixing ratio at 70 hPa is reduced during the most of the 20-th century (compared to the first decade of the 21-st century). This peculiarity of ozone spatial distribution we attribute to the energetic particles trapped in the Earth’s radiation belts, activating themselves ion-molecular reactions of ozone production in the region of Regener-Pfotzer ionisation maximum. Consequently, the spatial-temporal variations of the lower atmospheric ionisation could be a good explanation for irregularly distributed ozone and its regionally specified impact on the climatic variables.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
