Observations have been divided by seasons, geographical areas, vertical layers and intensity. The majority of turbulence observations reported from the layers of the upper part of troposphere. Turbulence observations, in the lower part of troposphere, principally, fixed in the planetary boundary layer and showed moderate and severe turbulence near main airports of the region under consideration. Possibility to define type of turbulence based on aircraft, surface and satellite observations and numerical modeling is discussed.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен анализ данных самолетных наблюдений за атмосферной турбулентностью над территорией Восточной Сибири и Дальнего Востока с января 2020 г. по июль 2024 г. Рассмотрено распределение данных о турбулентности по сезонам года, географическим районам, вертикальным слоям и интенсивности. Получено, что наибольшее количество сообщений о турбулентности поступает с уровней, относящихся к верхней тропосфере. Сообщения из нижней тропосферы относятся в основном к планетарному пограничному слою и содержат информацию только об умеренной и сильной турбулентности преимущественно в окрестности крупных аэродромов. Обсуждается возможность определения типа наблюдаемой турбулентности по данным самолетных сообщений в совокупности с данными наземных и космических наблюдений с целью совершенствования методов прогнозирования турбулентности, опасной для авиационных полетов, по данным численных моделей прогноза погоды.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mechanical turbulence</kwd><kwd>thermal turbulence</kwd><kwd>low-level turbulence</kwd><kwd>meteorological forecasts for aviation</kwd><kwd>Far East</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>механическая турбулентность</kwd><kwd>термическая турбулентность</kwd><kwd>турбулентность в нижних уровнях</kwd><kwd>метеорологические прогнозы для авиации</kwd><kwd>Дальний Восток</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Росгидромет</institution></institution-wrap><institution-wrap><institution xml:lang="en">Roshydromet</institution></institution-wrap></funding-source><award-id>1.4.4.2</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Verbickaja E.M., Romanskij S.O.
