Dali in Yunnan reflects the Yunnan plateau's Erhai Lake basin at 1,975 metres with the Cang Mountain backdrop, with vehicle traffic and Bai ethnic heritage tourism and agricultural corridor contributing local sources. Consistent plateau winds and lake breezes provide reliable ventilation and Dali generally maintains good to moderate conditions for a Chinese highland UNESCO heritage lake city throughout most of the year.
