By using the reanalysis data ofNCEP( 1°×1°) and the radiosonde and surface observations aswell as the Doppler radar products, the features of a strong dust storm occurred on 13 June 2008 in theHexiCorridor are analyzed. Results show that the upper cold airmoved fast and overlapped on the surface cyclone resulted inmeso-scale convection system developing fast. The dry-warmlid at the level of500-540 hPawas advantageous to the instability energy accumulation at low level and itwas importantomen for the strong convection weather.The convection system took place firstat the low layerbefore the sandstorm outbreak, then quickly developed tomiddle layer. The sandstorm occurred in theweak echo areawhichwas in frontof the strong echo and in the adversewind region of radial velocity
