Paleoclimate Reconstruction for Chungbu Mountainous Region Using Tree-ring Chronology

아한대 침엽수류 연륜연대기를 이용한 중부산간지역의 고기후복원

The paleoclimate of the Chungbu Mountainous Region, Mts. Seorak and Sobaek, was estimated by means of dendroclimatic methodology, The annual growth value of tree-rings is deeply interrelated with the mean temperature of April-May and July-August. The mean temperature of April-May of the reconstruction period(1635-1911), observation period(1912-1989), and the whole period(1635-1989) is 13.58$^{\circ}C$, 13.69$^{\circ}C$, and 13.6$0^{\circ}C$, respectively. That of July-August is $24.50^{\circ}C$, $24.62^{\circ}C$, and $24.58^{\circ}C$ respectively. The reconstructed mean temperature data for April-May and for July-August reveal 13.2 and 12.9 year cycles.
