Hengzhou in Guangxi reflects the flat Guangxi Yong River valley position adjacent to Nanning, with vehicle traffic on surrounding roads and the agricultural processing and manufacturing contributing local sources. Consistent South China southerly winds provide seasonal ventilation, while the subtropical monsoon's frequent summer rain provides effective atmospheric cleansing and the area generally maintains moderate Guangxi provincial corridor readings throughout most of the year.
