Abstract
The article assesses the dynamics of dust haze for the period 2010-2021 based on a number of ground-based observations conducted at the Tashkent Observatory weather station (Uzhydromet). A comparative analysis of the obtained characteristics with the data presented in scientific publications was performed. The features of the temporal distribution of this phenomenon have been identified. During the period under review, the total number of days with dust haze was 110, and its total duration was 482.9 hours. It has been established that dust haze is observed more frequently and lasts longer than dust storms. The maximum activity of the phenomenon was recorded in 2021. Pronounced seasonal fluctuations were noted with peaks in the winter and autumn months. An analysis of the duration of episodes showed that most of them last less than three hours, but there is a tendency towards an increase in the share of long-term events.
