초록

본 연구에서는 2019~2023년 동안 마산항 해역에서 관측된 자료를 활용하여 저시정 발생 시 해양 및 기상 요소의 변화를 분석하였다. 분석 결과, 저시정은 주로 겨울철부터 여름철 사이에 집중되었으며, 발생 시 해무와 비해무의 특성이 뚜렷하게 구분되었다. 해무는 주로 낮은 기온과 수온, 음의 해기차, 높은 상대습도, 약한 풍속 조건에서 빈번히 발생한 반면, 비해무는 여름철 고온·고수온 및 저기압 조건과 관련이 깊었다. 이러한 결과는 저시정 발생이 계절적 배경뿐만 아니라 대기·해양 상호작용 및 기상 조건의 변화와 밀접히 연관되어 있음을 보여준다.

Abstract

This study examines low-visibility events in the Masan Harbor area from 2019 to 2023, focusing on associated oceanographic and meteorological conditions. Results showed that low-visibility events predominantly occurred from winter to summer, with sea fog and non-sea fog conditions exhibiting distinctly different characteristics. Sea fog occurred more frequently under conditions of low surface air temperature (SAT) and sea surface temperature (SST), high relative humidity, and weak winds with negative sea-air temperature differences, whereas non-sea-fog events were associated with high SAT, high SST, and low-pressure conditions during summer. These findings demonstrate that low-visibility events are strongly influenced by not only seasonal background factors but also by changes in atmospheric–oceanic interactions and meteorological conditions.
