Abstract:
A professional meteorological station belonging to “Ion Luca Caragiale” National College is used to study the influence of meteorological parameters (temperature, relative humidity, pressure and wind speed) on particulate matter PM10 levels in the city of Ploiești. The daily and hourly values of the PM10 mass concentrations were extracted from the air quality monitoring stations in Ploiesti, which belong to the National Air Quality Monitoring Network in Romania. Analysis of measured data from all monitoring stations show the problem of air pollution is not specific to a certain area of the city. Although there are some days and hours in a day when pollution is most intense in a specific location, the phenomenon is generalized throughout the city. Apart from the mean situation of air pollution by PM10, six urban pollution events, produced from August 2018 to May 2021 were analyzed and comparatively presented. State-of-the-art open-access numerical research models such as HYSPLIT and US GFS model (Global Forecast System), the DWD models (German Weather Service) were used to analyze air-mass back trajectories and the meteorological conditions al local and synoptic scale. It has been shown that the atmospheric stability has an important role in the accumulation of PM10 particulate matter at the scale of Ploiesti urban agglomeration. High-school students participated in data collection and presentation of results in present study, understanding the concepts of physics, mathematics and computer science in an interdisciplinary context.
