This study investigated the characteristics and frequency of autumn typhoons affecting the Korean Peninsula during Period I (1954~2003), Period II (2002~2010), and Period III (2011~2019). As a result of analysis of all typhoons since 1954, the frequency of typhoons during June~August has decreased more recently than in the past. In contrast, the number of autumn typhoons in September and October was almost 20% of the total number of typhoons during Period I, but increased by 31.6% during both Periods II and III. According to an analysis of the distribution of the maximum 3-Second gust, the area of strong gust over 33 m/s, which was concentrated in parts of the North Korea, the Korea Strait, and Japan, during Period II, was expanded to the entire Korean Peninsula during Period III. Also we can find the strength and intensity of the typhoon increased compared to the past from analysis of the characteristics of 3-Second gust in the Autumn typhoon. KCI Citation Count: 0
