A review on applicability evaluation of four reanalysis datasets in China
摘要
Abstract
The applicability of four reanalysis datasets in regional climate change research in China are reappraised and summarized,including NCEP/NCAR dataset,NCEP/DOE dataset,ERA-40 dataset and JRA-25 dataset.The results indicate that four datasets are of some commonness and also of discrepancies in different region and different time scales.Probably due to the distribution features of meteorological stations in China,namely,dense in the eastern China and sparse in the western China,the reliability of the reanalysis datasets is generally better in the eastern than in the western China,and greater in low latitude area than in high latitude area.The reanalysis datasets have the greater uncertainty before 1979,so it should be more cautions to use the NCEP/NCAR reanalysis dataset of this period,especially for the study of long-term climate change.The applicability of different variables of reanalysis datasets is different at different time scales and areas,so the optimum dataset should be selected based on area,element and season.Finally,merit and shortage of reanalysis datasets and applicability in China are summarized.This study could provide references for choosing reanalysis datasets of the regional climate change research.关键词
