In this paper, in order to recognizing of moisture resources of western part of Iran and water vapor transport quality from surrounded around areas to this region were selected. The study of specific moisture distribution and precipitable water in the study area indicate that the moisture from two days before precipitation start on the Iran, in lower levels of troposphere from southern region of Red sea and Aden gulf, to north of middle east and then from precipitation start day to east (west of Iran) were replaced. Calculated moisture flux values have indicated that Arab and Oman seas in study period have the heights divergence of moisture flux specifically in lower levels of troposphere. But the role of Red sea in middle levels is clear. The result of this study indicates that eastern Mediterranean Sea not only has not moisture sending but also from Oman, Arab, Red Seas and theirs central part moisture received. The highest moisture in precipitation days on the Iran observed in the lower levels of troposphere that are equal only in northwest region, moisture transition rate in lower levels and middle of troposphere. Also the result indicates that Oman Sea and Arab sea are the most important resources of moisture supply of occurred precipitation on the west of Iran.
