摘要

摘要我们利用ERA5再分析数据（1979-2021年）对北半球大气中反气旋的空间和季节特征及其近几十年的变化进行了定量估计。研究发现，在北半球外热带纬度的广大地区，反气旋平均季节发生率的年际变化与近地表温度之间存在高度相关性。据估计，冬季和夏季近地面温度年际变化的 60%与反气旋平均季节发生率的变化有关，50%与冬季和夏季强反气旋的变化有关。

Variability of the Atmospheric Anticyclones and Their Connection with Surface Temperature Variations in Extratropical Latitudes of the Northern Hemisphere in Recent Decades

Abstract

We have obtained quantitative estimates of the spatial and seasonal features of the characteristics of anticyclones in the atmosphere of the Northern Hemisphere and their changes in recent decades using ERA5 reanalysis data (1979–2021). A high correlation between the interannual variations of the mean seasonal occurence of anticyclones and near-surface temperature over extensive regions in the extratropical latitudes of the Northern Hemisphere is noted. According to the estimates, up to 60% of the interannual variance of near-surface temperature in winter and summer is associated with variations in the mean seasonal occurence of anticyclones and up to 50% with variations of intense winter and summer anticyclones.

期刊介绍： Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
