The Asian summer monsoon mechanism and the role of its forcing’s on regional atmospheric circulation are considered challenging topics. Based on this issue, it was tried to investigate the interaction effect of summer monsoon in severe periods in connection with the increase of dust in the Middle East and Iran. To achieve this goal, ERA5 data with a resolution of 0.25 degrees was used. In the following, using dynamic and physical indicators, changes in monsoon meteorological parameters were investigated in relation to the beginning and end of summer in the region. Finally, after identifying the strongest summer monsoon periods, the relationship between the meteorological parameters and the AOD values of the MODIS meter was investigated. The results showed that summer in the region starts from the beginning of June and continues until the end of September based on the Vorticity changes and the slope of the temperature changes. During this situation, two Low level jet streams of Sistan and North have been operating in the east and west of the Iranian plateau, which play the main role in the transfer and distribution of dust in the region. With the strengthening of the summer monsoon, the subtropical highs in the middle and upper troposphere have an upward jump and expansion in the direction of longitude, and in this direction, negative Vorticity increases over Iran.
