Abstract :

Dust is one of the destructive phenomena of climate that annually makes a lot of damage to theenvironment, roads, buildings and urban air. Western Province of Iran are susceptible places forfrequent occurrence of dust phenomenon. For this study the data of horizontal visibility and reporteddust phenomena of several meteorology stations in the western provinces were used. Afterdetermining the days with dust and their classification, we attempted to extracted maps of differentlevels of the meteorology International Centre from the NOAA. Finally, the maps and data of dustwere analyzed in the case study. The results showed that the reduction of soil moisture reduced due todecreasing precipitation over the past decade, particularly in the north the middle east, that is feedingregion's the major rivers of Mesopotamia and also, increasing frequency of the short waves and rapidwith strong wind-orbital are the main reasons of storms. It appears that on strengthening subtropicalhigh pressure on Saudi Arabia and simultaneously expanding and opening lines 588 D kamtrIntermediate levels causing increasing the speed of short waves and reduction moisture the advectionfrom high latitudes to the south of the study area. This mechanism reduces the depth of Mediterraneandescent wind conditions also triggers orbital and is weakened meridional currents. It also weakenedthe landing place to the Mediterranean and towards higher latitudes and raise subtropical high pressurecenter can be another reason for the displacement of dust to the north a source.
