An Analysis of a Winter-time Temperature Change and an Extreme Cold Waves Frequency in Korea

To compare changes in winter temperature over South Korea, 30-year average climate data and climate data of recent 10 years (2014∼2014) such as mean temperature, daily maximum temperature and daily minimum temperature were analyzed. Also, we set analysis extreme cold waves frequency related to winter such as freezing days, snow days, days with temperature of below ?5, and days with temperature of below ?10. This process enabled the comparative analysis of winter temperature changes and extreme cold waves frequency related to winter. This study estimated that winter temperature has gradually increased throughout the last five decades, however, the frequency of extreme weather, such as cold waves has also increased.
