초록

본 연구에서는 제주도 해안가의 대기중 염분 분포 특성을 파악하였다. 이를 위해 제주도를 동, 서, 남, 북부지역의 4개 지역으로 구분하여 대기중 염분량을 조사하고, 지역별, 계절별 특징을 분석하였다. 아열대 기후이면서 섬으로 형성된 제주도는 대기중 염분량 분포에 있어서 지역별 편차가 크며 가장 높은 지역인 동부와 가장 낮은 지역인 남부 지역은 6배 이상 차이가 났다. 계절별 특징으로는 동부와 서부는 태풍의 영향으로 각 각 여름/가을철과 여름철이 높고, 북부는 북서풍의 영향으로 겨울철이 높으며, 남부는 여름철이 높았다. 한편 국내 동, 서, 남해안의 대기중 염분량과 비교하여 제주도는 높은 경향이 있다.

The distribution properties of airborne chlorides at the coasts of Jeju island were identified in this study. For this, Jeju island was divided into four regions-east, west, south, and north, and the airborne chlorides were investigated in those regions. And the regional and seasonal distribution properties of airborne chlorides were analyzed. Jeju island, which has a subtropical climate and is surrounded by ocean, has a great regional variation in the distribution properties of airborne chlorides, with a difference of more than 6 times between the eastern region, the highest region, and the southern region, the lowest region. In terms of seasonal properties, the airborne chlorides in eastern and western region were high in summer and fall, and in summer mainly due to typhoon. The airborne chlorides in northern region were high in winter due to the northwest wind, and the that of southern region were high in summer. Meanwhile, the airborne chlorides of Jeju island tends to be high compared to the eastern, western, and southern coasts of South Korea.
