Dust storm is relate with climate change specially with semi-arid region, this research is concerned with studying the synoptic pattern and anaerobic variables and their relationship with dust storms and identifying the main types of patterns synchronized with dust storms. The research relied on the Atmospheric dynamic and synoptic analysis of weather maps related to dust storms over Iraq. The study focused on the dust storms factors affecting them (air temperature, wind speed) .The analysis of weather maps of the surface (MSL) explained the presence of pressure low and high pressure and their impact on Iraq, the Gulf states and Saudi Arabia. The results of the contour lines geopotentail high at the pressure level 500 (hPa) and growth the trough and ridge. In addition to the dynamic analysis of weather maps at the pressure level 850 (hPa) and the interpretation of wind movement, speed and change of direction within this level.The significant results showed that dust storms occur during the summer and spring months, the winds were northwesterly heading south or east, these winds were very fast winds that pass over Iraq from the Iraqi-Syrian border, causing the lifting of dust particles from arid or/and semi-arid areas, which are sources of dust.
