Dust storm in China of March-April in 2002 is studied on its frequency, together with the monthly and pentad circulation pattern, using surface observation and NCEP/NCAR reanalysis. It shows that it is the development and intensification of East Asian trough, a prevailing circulation pattern over the north, northeast even central China, that result in the more occurrence of dust storm along near northern track. The sub cold front developed by the maintenance of the northeast cyclone could bring up strong local dust storm. Further analysis of sand and dust transportation in the northeast cyclone weather pattern gives the spatial distribution of the dust and sand along the track of dust storm in the light of GMS-5 TBB data. It indicates that strong dust storm could develop to the northeast, influencing on the area of northeast, for East, even further north, in the case of strong northeast cyclone.
