By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.
