By the combination of ground detection and satellite, the source and development process of strong dust storm in the northwest provinces, including Xinjiang, Gansu, Neimenggu, Ningxia, etc., occurred in November 17 to 18, 2016, is discussed by using the optical properties of aerosols. The ground detection equipments were used to measure the extinction coefficient and optical depth of dust aerosol near the source. The evolution path, formation process and cause of dissipation of dust storm were analyzed by satellite data. The reason why dust storm is not easy to spread to the eastern part of China is preliminarily given.
Key words: dust storm / optical property / long range transportation
