Calculations of the nucleation rates and particle number concentrations were performed for the winter period in the troposphere using a unified model that takes into account chemical and kinetic transformation processes (photochemistry, nucleation, condensation/evaporation, and coagulation). Binary nucleation of sulfuric acid and water vapor was coupled with new-particle formation due to atmospheric ions. The numerical results indicate a significant role of ion nucleation in aerosol formation in the Northern and Southern hemispheres in winter. The factors controlling the dynamics of ionic processes in the atmosphere and their influence on the spatiotemporal distribution of aerosol particles involve not only the level of air ionization but also temperature, relative humidity, and the content of sulfur and water vapor in the air. At a height of 4.2 km, the formation of particle nuclei with the participation of ions occurs only over the Lake Baikal and Kamchatka regions as well as the regions of the northeast and northwest of the American continent. Within the regions of localization of this process in the atmosphere, the rate of new particle generation varies by more than an order of magnitude.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181326058560">Построена новая математическая модель глобального переноса многокомпонентных газовых примесей и аэрозолей, включающая формирование в атмосфере сульфатных аэрозолей в обоих полушариях. Расчеты скоростей нуклеации и счетных концентраций частиц выполнялись применительно к зимнему периоду в тропосфере в рамках единой модели с учетом химических и кинетических процессов трансформации (фотохимия, нуклеация, конденсация/испарение и коагуляция). При этом наряду с бинарной нуклеацией паров серной кислоты и воды рассматривалось также образование зародышей частиц и с участием атмосферных ионов. Полученные результаты указывают на значимую роль процесса ионной нуклеации в формировании аэрозоля в Северном и Южном полушариях в зимнее время. Наряду с уровнем ионизации воздуха, факторами определяющими динамику ионных процессов и их влияние на пространственно-временное распределение аэрозольных частиц в атмосфере, являются температура, относительная влажность, а также содержание в воздухе паров серной кислоты и воды.</p></trans-abstract><kwd-group xml:lang="en"><kwd>numerical model</kwd><kwd>atmosphere</kwd><kwd>aerosol</kwd><kwd>ion nucleation</kwd><kwd>binary nucleation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>численная модель</kwd><kwd>атмосфера</kwd><kwd>аэрозоль ионная нуклеация</kwd><kwd>бинарная нуклеация</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского фонда фундаментальных исследований 19-05-50007 (Микромир), а также при финансировании Госзаданий ИВМ РАН и ИНЭП ХФ РАН им.
