SENSITIVITY OF PARTICULATE MATTER (PM) TO CLIMATIC VARIABLES IN ARID REGIONS
This study examines the large fluctuations in fine particle concentrations reported in the air of Dammam's industrial city because of abrupt changes in meteorological conditions during the investigation of air quality in the region. In terms of the data bought, the study is essential and useful for clarifying the influence of climate change on air pollution in arid - desert locations. The main important findings of this study are listed below: The relative humidity (RH) has risen by 144.6 percent, causing a substantial increase in PM concentration. The concentrations of PM2.5 and PM10 increased to 251 percent and 307 percent respectively, while Total Suspended Particles (TSP) concentrations climbed to 315 percent. To explore the relationship between air pollutants (PMs) and meteorological factors, correlation and regression analyses were used. It’s found that air pollutants such as PM2.5, PM10, and TSP had substantial positive correlations with RH but are negatively linked with ambient temperature when linear regression models used to explore the association of PMs with meteorological factors.
