Analysis of Sandstorm Characteristics and Influence Factor in Southern Mongolia

Southern of Mongolia is area where dust storm arises and fleets. The reason that dust storm arises is regular wind from western as well as structure of mountains in Mongolia. The result of reason was made based on data from 2 stations of Gobi-Altai aimag, March, April and May in 2004-2013. The note of dust storm (wind force, wind energy and the number of dust storm days), wind speed, humidity, temperatures and wind direction were compared for making the result. The results show, climate factors of 2 stations were affected for being different on the number of dust storm days. The precipitation with less temperature was more in Ajbogd station and the precipitation with much temperature was less in Tooroi station. Also the effect of cyclone from structure of mountains maybe was there except for climate factors.
