The difference in the uncertainty sources between future projections of mean and extreme precipitation over East Asia

Autor: Ana Juzbašić, Changyong Park, Dong-Hyun Cha, Joong-Bae Ahn, Eun-Chul Chang, Seung-Ki Min, Youngeun Choi, Young-Hwa Byun

Publikováno v: Environmental Research Letters, Vol 19, Iss 7, p 074015 (2024)

As the incidence of extreme precipitation events attributable to global climate change increases, providing policymakers with accurate model predictions is of the utmost importance. However, model projections have inherent uncertainties. The present

Future changes in extreme heatwaves in terms of intensity and duration over the CORDEX-East Asia Phase Two domain using multi-GCM and multi-RCM chains

Autor: Young-Hyun Kim, Joong-Bae Ahn, Myoung-Seok Suh, Dong-Hyun Cha, Eun-Chul Chang, Seung-Ki Min, Young-Hwa Byun, Jin-Uk Kim

Publikováno v: Environmental Research Letters, Vol 18, Iss 3, p 034007 (2023)

An extreme heatwave, in terms of intensity and duration, is projected to occur at the end of the 21st century (2071–2100) over the whole of East Asia. The projection is calculated using daily maximum temperature data of 25 km horizontal resolution
