Hazes showed a generally rising trend over the past 45 years, but a slightly falling trend after 2000. The inter-annual variation of hazes was obvious. When a haze occurred, the visibility mostly ranged from 5 to 10 km, and the relative humidity ranged from 70% to 90%. The day number of hazes was proportional to temperature, but inversely proportional to wind speed.
