ABSTRACT: Based on
hourly observation data from 2016 to 2019 and hourly automatic
meteorological observation data from 2018 to 2019, we analyzed the annual,
monthly and daily variation characteristics of fog days in Ninglang Airport,
and diagnosed a case of summer fog. The results show that the average annual
fog days in Ninglang Airport are 128 days and the annual characteristic of fog
days is bimodal. Analyzed on fog cases
in 2019, it was a summer fog process lasting more than 20 hours and visibility
less than 500 m. The
data from the automatic observational stations around Ninglang airport can describe the near-surface layer features of fog and
illustrate the progress of fog. The meteorological elements of automatic
observational stations changed suddenly 2 hours before fog, so the data of the
automatic observational stations can be used to forscast fog.
