Abstracts

This article presents the results of projection of abnormal cold surge in winter in the Northern region of Vietnam for the period 2020–2100 based on the regional climate model RegCM under different scenarios Climate change RCP4.5 and RCP8.5 are generated from five Atmospheric–Ocean Global Circulation Models (AOGCM) including CNRM–CM5, CSIRO, MPI–ESM, EC–Earth and GFDL–ESM. The magnitude and variability of abnormal cold surge vary considerably across scenarios and across different global inputs. The estimated results show a decreasing trend of abnormal cold surge in winter over the Northern region in the period 2020–2100 under both scenarios RCP4.5 and RCP8.5. The reduction under the RCP8.5 scenario is larger than that of the RCP4.5 scenario. The frequency of abnormal cold surge in the early 21st century is higher than in the middle and late 21st century.
