Youn, D. and Park, Y.H., 2021. Climate change: Characteristics of storms around Korea. In: Lee, J.L.; Suh, K.-S.; Lee, B.; Shin, S., and Lee, J. (eds.), Crisis and Integrated Management for Coastal and Marine Safety. Journal of Coastal Research, Special Issue No. 114, pp. 256–260. Coconut Creek (Florida), ISSN 0749-0208. Many studies have shown that the intensity and frequency of storms are increasing due to global warming. Because storms are affected by many factors, such as the climate and sea, the relationships of some factors still need to be studied for better understanding. Most recent storm studies have focused on increasing the accuracy of numerical model simulations; however, this study employs statistical methods to find the correlation among factors that determined storm characteristics. Correlation analysis was conducted using certain factors in the ocean and atmosphere. The analysis was conducted using R software for statistical computing of the selected storms passing near the Korean Peninsula, considering the difficulty of storm study. Typhoons occurring in the last 40 years were analyzed, and the relationships of many variables were calculated. The number of typhoons heading for Korea has increased, but the increment of their intensity was not apparent in the observational data. Unlike previous methods, this work was conducted for typhoons that passed through a defined area on the southern coast of the Korean Peninsula. In the region between 30° and 35° N, typhoon paths changed to move northeast instead of being dominated by the Westerlies. Typhoons starting at lower latitudes and more easterly locations tend to develop into strong typhoons, and typhoons starting at lower latitudes tend to be larger. |
