Abstract

Abstract: Meteorological factors affecting visibility in Yuzhong county of Lanzhou city from 2005 to 2015 were analyzed based on the observation data of atmospheric visibility. Using the method of multiple linear regression, the forecast equation of visibility in Yuzhong county was established, and the data of 2016 were substituted into the forecast equation for testing. Finally, the forecast value of visibility in Yuzhong county in 2016 was obtained, and the measured value and forecast value of visibility in Yuzhong county in 2016 were compared and analyzed. The results showed that the visibility in Yuzhong county was relatively good in summer and autumn, but in spring due to the appearance of dust weather and more windy weather had a greater impact on visibility. In winter, it was the mainly influence of fog and haze weather and the smoke generated by burning coal for heating in rural areas.

Key words: visibility, factor analysis, forecast, Yuzhong county
