초록

The purpose of this study is to uncover the climatological characteristics of Yangganjipung, a strong local wind blowing in Yeongdong region, Korea, which has recently attracted attention as an exacerbation factor of wildland fire spread. Analyses of 20-year (2000-2019) surface climate data observed by the Korea Meteorological Administration demonstrate that strong westerly winds exceeding 20 m/s (25m/s in mountainous areas) more frequently occur in the northeastern coastal region (between Yangyang and Goseong) of Gangwon province rather than the southeastern coastal region, evidencing the existence of Yangganjipung. The intensification of Yangganjipung may be associated with the convergence of strong westerly winds along a southwest-northeast directional tectolinement connected to the western flank of the Taebaek Mountain Range. It is also notable that Yangganjipung tends to occur seasonally between late fall and late spring and diurnally between afternoon and nighttime hours. Examinations of the composited maps of NCEP-NCAR reanalysis data for multiple cases reveal that the formation of a low pressure anomaly core around northern East Sea provides the favorable condition for long-lasting, intense Yangganjipung occurrences. These results are expected to be used as the basic data for establishing a gusty wind warning system to prevent regional-scale climate disasters associated with Yangganjipung such as large-scale forest fires in the eastern coast of the Korean Peninsula.
