In order to analyze the meteorological factors cause changes in air quality, the plan is to classify the weather patterns and high-pressure locations of 2014-2018. In addition, this is also study the correlation between the types of flow fields in the vicinity of Taiwan and the distribution of air pollution in 2013-2017. And according to the research results, we have built a database to quickly search the information in the past to provide reference for forecasters.
The second part, to establish a ventilation index (VI) forecasting operation process, and cooperate with the EPA to provide a ventilation index (VI) forecast before the daily forecast. And continuous this study the correction between ventilation index (VI) and air quality from the spatial and temporal distribution characteristics of the Taiwan of 2016-2018. The results show that ventilation index (VI) and PM2.5 pollutant concentrations have opposite trends.
This project We also analysis the causes of air pollution episodes include the flow flied of surface and boundary layer. A total of six reports were provided. On the other hand, we made 2 implemented training programs to the staff of the department, and communicated the correct message of the air quality policy and the causes of pollution to the public.
