The National Institute of Meteorological Sciences-Korea Meteorological Administration (NIMS-KMA) has participated in the Coupled Model Inter-comparison Project (CMIP) and provided long-term simulations using the coupled climate model. The NIMS-KMA produces new future projections using the ensemble mean of KMA Advanced Community Earth system model (K-ACE) and UK Earth System Model version1 (UKESM1) simulations to provide scientific information of future climate changes. In this study, we analyze four experiments those conducted following the new shared socioeconomic pathway (SSP) based scenarios to examine projected climate change in the twenty-first century. Present day (PD) simulations show high performance skill in both climate mean and variability, which provide a reliability of the climate models and reduces the uncertainty in response to future forcing. In future projections, global temperature increases from 1.92 °C to 5.20 °C relative to the PD level (1995–2014). Global mean precipitation increases from 5.1% to 10.1% and sea ice extent decreases from 19% to 62% in the Arctic and from 18% to 54% in the Antarctic. In addition, climate changes are accelerating toward the late twenty-first century. Our CMIP6 simulations are released to the public through the Earth System Grid Federation (ESGF) international data sharing portal and are used to support the establishment of the national adaptation plan for climate change in South Korea.

基于新的温室气体浓度路径的NIMS-KMA CMIP6模型模拟的二十一世纪气候变化预测

国立气象科学研究院-韩国气象局(NIMS-KMA)参加了耦合模型比对项目(CMIP),并使用耦合气候模型提供了长期模拟。NIMS-KMA使用KMA高级社区地球系统模型(K-ACE)和英国地球系统模型版本1(UKESM1)模拟的综合平均值来产生新的未来预测,以提供有关未来气候变化的科学信息。在这项研究中,我们分析了四个实验,这些实验是根据新的基于共享社会经济途径(SSP)的情景进行的,以检验二十一世纪的预期气候变化。目前(PD)的模拟显示出在气候均值和多变性方面的高性能,它提供了气候模型的可靠性,并减少了对未来强迫的不确定性。在未来的预测中,相对于局部放电水平,全球温度将从1.92°C升高到5.20°C(1995-2014)。全球平均降水量从5.1%增加到10.1%,海冰范围在北极从19%降低到62%,在南极从18%降低到54%。此外,到二十一世纪末,气候变化正在加速。我们的CMIP6模拟通过地球系统网格联合会(ESGF)国际数据共享门户向公众发布,并用于支持制定韩国应对气候变化的国家适应计划。全球平均降水量从5.1%增加到10.1%,海冰范围在北极从19%降低到62%,在南极从18%降低到54%。此外,到二十一世纪末,气候变化正在加速。我们的CMIP6模拟通过地球系统网格联合会(ESGF)国际数据共享门户向公众发布,并用于支持制定韩国应对气候变化的国家适应计划。全球平均降水量从5.1%增加到10.1%,海冰范围在北极从19%降低到62%,在南极从18%降低到54%。此外,到二十一世纪末,气候变化正在加速。我们的CMIP6模拟通过地球系统网格联合会(ESGF)国际数据共享门户向公众发布,并用于支持制定韩国应对气候变化的国家适应计划。
