초록

본 연구에서는 2016~2025년 평택과 목포의 기상 및 해양 관측자료를 활용하여 저시정 발생 특성을 비교하였다. 두 해역 모두 해무는 봄철에 집중되었으며, 그 비율은 목포(49.3%)가 평택(36.3%)보다 높았다. 평균 해기차(SST−SAT)는 평택 -0.3°C, 목포 +0.5°C로 차이를 보였으며, 봄철 짙은 해무에서 양의 해기차 비율은 각각 68.3%와 86.8%로 나타났다. 이는 동일한 서해안에서도 지역적 해양환경에 따라 해무 발생 특성이 상이함을 보여준다.

Abstract

This study compared low-visibility characteristics in Pyeongtaek and Mokpo using meteorological and oceanographic observations from 2016 to 2025. Sea fog occurred predominantly in spring, accounting for 49.3% of annual sea fog duration in Mokpo and 36.3% in Pyeongtaek. The mean sea–air temperature difference (SST−SAT) was −0.3°C in Pyeongtaek and +0.5°C in Mokpo, while positive differences during dense spring sea fog occurred in 68.3% and 86.8% of cases, respectively. These results indicate regional differences in sea fog characteristics associated with local oceanographic conditions along the western coast of Korea.
