   <abstract xml:lang="ru">
    <p>Работа основана на данных о характеристиках естественного свечения верхней атмосферы Земли, генерируемого атомарным кислородом на длине волны 630 нм, полученных при помощи интерферометра Фабри—Перо (ИФП) Национального гелиогеофизического комплекса. ИПФ установлен в Геофизической обсерватории (ГФО) Института солнечно-земной физики СО РАН (с. Торы, 52° N, 103° Е). Измерение доплеровского смещения линии свечения и последующее соотнесение его   с направлением луча наблюдения позволяют восстанавливать величины зональной и меридиональной компонент горизонтального ветра в ночной и сумеречные периоды суток. В работе проводится анализ сезонной динамики компонент нейтрального ветра в 2022 г. по данным интерферометра Фабри—Перо и вычислениям по моделям HWM93, HWM07        и HWM14. Анализ выполнен для локальной ночи 10–24 UTC. Данные были разделены по сезонам относительно дней солнцестояния и равноденствия, а также отфильтрованы по условию наличия облачности.&#13;
Расхождение между значениями модели и измерениями каждого компонента ветра варьирует как в течение суток, так и в зависимости от сезона. При этом можно заключить, что ни одна модель не дает приемлемого согласования с измеренными величинами и предоставляемые моделью HWM значения ветра для Байкальского региона не следует рассматривать как точные. Развитие настоящей работы позволит выработать рекомендации по коррекции или улучшению модели HWM с целью более точного описания динамики верхней атмосферы региона. Полученные в работе результаты будут также полезны при выборе версии модели нейтрального ветра для расчетов заданной компоненты ветра в заданный сезон.</p>

    <p>This study is based on observations of the atomic oxygen airglow emission at 630 nm obtained with a Fabry—Perot interferometer (FPI) of the National Heliogeophysical Complex. FPI is installed in the Geophysical Observatory of the Institute of Solar-Terrestrial Physics SB RAS (Tory, 52° N, 103° E). Doppler shifts of the emission line were measured and then converted into horizontal wind velocities along the zonal and meridional directions during nighttime and twilight periods. We analyze the seasonal variability of neutral wind components during 2022, using both FPI measurements and model calculations from three versions of the Horizontal Wind Model: HWM93, HWM07, and HWM14. The analysis covers local nighttime hours (10–24 UTC). The data was separated by seasons relative to solstices and equinoxes and filtered by cloud conditions.&#13;
The discrepancies between modeled and observed wind components vary with both local time and season. None of the HWM versions provide acceptable agreement with the measurements, indicating that HWM outputs for the Baikal region should not be considered accurate. The results of this study can be used to develop recommendations for improving or adjusting HWM in order to better describe the dynamics of the upper atmosphere in the region. These findings are also useful when choosing the most suitable HWM version for estimating a specific wind component in a given season.</p>
