主 题：Gale Dust Causes Zhangjiakou City
摘 要：On May 11,2011, the gale and dust weather appeared in Zhangjiakou City. By analyzing the conventional meteorological data, it was found that the gale and dust weather occurred by the combined effect of the cold air splitting from the bottom of the high-altitude cold vortex and the Mongolian cyclone. The strong cold advection in the middle and lower layers provided the gale weather with driving force. The humidity conditions at middle and lower layers in Zhangjiakou City and its upstream region contributed to the weather process. Finally, the strong and wide rise district provided a more favorable power condition for the maintenance and transmission of the dust to the eastern region.
