原始语种摘要: The distribution of dust aerosols in dust devils (DDs) is quantitativelycharacterized here based on a field observation. We applied the digitaloptical method (DOM) with digital still cameras to quantify the opacity ofthe DDs in the Taklimakan Desert, China. This study presents the followingunique and important results: (1) the distinct horizontal distributions ofopacity proved the existence of DDs' eye, similarly to the eye of tropicalcyclone; (2) the opacity of the DDs decreases with increasing height;however, the dust aerosols do appear to settle out, and the relatively calmeye leads to a minimum in dust opacity at the eye; (3) the horizontaldistribution of opacity is quasi-symmetric with a bimodal across the eye ofthe DDs, which could be resulted from the ambient air conditions; and...
