Based on the basic observationaldata and automaticweather station data, a regionalheavy dust storm occurred onApril29,2009 inHexiCorridorwas analyzed from the causes of the synopticmeteorology, physics quantity fields and so on.The results show that itwas a duststorm thatcaused by the gale behind the cold front, and ithappened in the zone ofstrong pressure gradient. Groundmeteorological elements had a strong response to the outbreak of the dust storm, which can be used as a reference for forecast of dust storms. Therewas an obvious upwardmotion in the outbreak area ofduststorm with the lower level convergence and the high-leveldivergence. The frontogenesis function and helicity indicated the area of dust storm verywel.l
