Mokpo, nestled on the southwestern coast of the Korean Peninsula in Jeollanam-do Province, presents a unique geographic setting that significantly influences its air quality. The city occupies a relatively flat coastal plain, averaging around 30 meters in elevation, bordered by the Yellow Sea. This proximity to the sea introduces maritime influences, moderating temperatures but also facilitating the transport of pollutants from both domestic and international sources. Mokpo’s urban character is defined by its port, historically a crucial hub for trade and fishing, and a growing industrial sector focused on shipbuilding and petrochemicals. Surrounding the city are agricultural lands, particularly rice paddies, and hilly terrain further inland. The urban-rural gradient is relatively sharp, with denser development concentrated around the port and city centre, transitioning quickly to agricultural and natural landscapes. The prevailing winds, often originating from the northwest during colder months and the southeast during warmer periods, play a critical role in dispersing or concentrating pollutants. The city’s location within a coastal basin can sometimes trap air masses, exacerbating pollution episodes, particularly during periods of calm weather. Industrial activity concentrated along the coast contributes to localised emissions, impacting air quality in nearby residential areas. The topography limits natural ventilation, increasing the potential for pollutant build-up.

Mokpo’s air quality follows a distinct seasonal pattern. Spring (March-May) often sees increased particulate matter from yellow dust storms originating in the Gobi Desert, carried by prevailing westerly winds. These events can significantly degrade air quality, impacting respiratory health. Summer (June-August) brings the monsoon season, with heavy rainfall effectively washing away many pollutants, resulting in generally cleaner air. However, high humidity can contribute to the formation of secondary pollutants like ozone. Autumn (September-November) is typically the most pleasant period for air quality, with stable atmospheric conditions and moderate temperatures. However, agricultural burning practices in surrounding areas can lead to localised spikes in particulate matter. Winter (December-February) presents the most challenging conditions. Temperature inversions, common during cold, stable weather, trap pollutants near the ground, leading to increased concentrations of fine particulate matter and nitrogen dioxide from heating sources and industrial emissions. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor activity during these periods. Fog, frequent in winter, can further exacerbate pollution by trapping pollutants. Months to avoid prolonged outdoor exposure are typically January and February, while June and September generally offer the best air quality.
