An Analysis of the Characteristics of Adjacent Climatic Factors Affecting Extreme Snowfall on the Korean Peninsula

Due to global warming, Arctic temperatures are rising, resulting in the fall of polar vortex, a cold Arctic air, causing heavy snow and a record-breaking cold wave in the middle latitude northern hemisphere. A record-breaking cold wave and extreme snowfall have paralyzed infrastructure and caused enormous human and property damage. In this study, we analyzed the deployment characteristics of winter climate that affect the extreme snowfall on the Korean Peninsula. The European Centre for Medium-Range Weather Forecasting (ECMWF) data provided by the Copernicus Climate Change Service (C3S) was used to analyze the characteristics of climate factors around the Korean Peninsula. The period of all data was from November to March, the winter season of South Korea. Teleconnections were analyzed using climatic factors such as snowfall, humidity, air pressure, wind and sea surface temperature to analyze the characteristics of climate factors affecting the heavy snowfall on the Korean Peninsula. The results of the future main study are expected to be used as basic data to predict the occurrence and impact of heavy snow in areas surrounding the Korean Peninsula in the future and to assess its vulnerability to damage from the snowfall.
