The Classification of Climate Types and the Delineation of their Climatic Characteristics Using New Normals (1991-2020) in the Republic of Korea
pp.179-195
The purposes of this study were to classify detailed climate types over the Republic of Korea (ROK) and to delineate their climate characteristics using the new normals of 1991-2020 for 219 weather stations. Total five climate types, Cfa, Cfb, Cwa, Dwa, and Dwb were identified in ROK based on the Köppen’s climate classification criteria. Subtropical climate types, Cfa or Cwa types were broadly covered with 79.9% of 219 stations and the most of remaining stations were included in Dwa types which had a very cold winter and hot summer with wet conditions. In the Trewartha classification, four climate types were identified, one subtropical Cfa, and three temperate Doa, Dca, and Dcb types. Dcb types were found at four stations (Daegwallyeong, Taebaek, Jinburyeong, and Sabuk) in Taebak mountains indicating the extent of cool summer climate types with more stations in mountain areas. The climate characteristics by climate types only were presented the results from the Trewartha classification with the new normals and 66 ASOS stations because Köppen’s climate classification was not appropriate for ROK. The annual mean precipitation of Cfa was the greatest while Dcb the lowest among four types. The annual range was the greatest at Dca types while the smallest at Cfa due to the geographical varieties. More detailed climate types were located in ROK with 219 weather stations and the new normals (1991-2020). However, there were some limitation applying the criteria of Köppen’s and Trewartha’s climate classification to a very complex topographical region.
