  • The representation of the Arctic stratospheric circulation and the quasi-biennial oscillation (QBO) during the period 1981–2019 in a 40-yr China’s global reanalysis dataset (CRA-40) is evaluated by comparisons with the two widely used reanalysis datasets, ERA-5 and MERRA-2. CRA-40 has a comparable performance with ERA-5 and MERRA-2 in characterizing the winter and spring circulation in the lower and middle Arctic stratosphere. Specifically, differences in climatological polar-mean temperature and polar night jet among the three reanalyses are within ±0.5 K and ±0.5 m s–1, respectively. The onset dates of the stratospheric sudden warming and stratospheric final warming events at 10 hPa in CRA-40, together with the dynamics and circulation anomalies during the onset process of warming events, are nearly identical to the other two reanalyses with slight differences. By contrast, CRA-40 has deteriorated performance in describing the QBO below 10 hPa compared to the other two reanalysis products, as manifested by the larger easterly biases of the QBO index, the remarkably weaker amplitude of the QBO, and the weaker wavelet power of the QBO period. Such pronounced biases are mainly concentrated in the period 1981–1998 and largely reduced by at least 39% in 1999–2019. Thus, particular caution is needed in studying the QBO based on CRA-40. Compared to the lower and middle stratosphere, all the three reanalyses have greater disagreement in the upper stratosphere in both the polar region and the tropics.

    Abstract: The representation of the Arctic stratospheric circulation and the quasi-biennial oscillation (QBO) during the period 1981–2019 in a 40-yr China’s global reanalysis dataset (CRA-40) is evaluated by comparisons with the two widely used reanalysis datasets, ERA-5 and MERRA-2. CRA-40 has a comparable performance with ERA-5 and MERRA-2 in characterizing the winter and spring circulation in the lower and middle Arctic stratosphere. Specifically, differences in climatological polar-mean temperature and polar night jet among the three reanalyses are within ±0.5 K and ±0.5 m s–1, respectively. The onset dates of the stratospheric sudden warming and stratospheric final warming events at 10 hPa in CRA-40, together with the dynamics and circulation anomalies during the onset process of warming events, are nearly identical to the other two reanalyses with slight differences. By contrast, CRA-40 has deteriorated performance in describing the QBO below 10 hPa compared to the other two reanalysis products, as manifested by the larger easterly biases of the QBO index, the remarkably weaker amplitude of the QBO, and the weaker wavelet power of the QBO period. Such pronounced biases are mainly concentrated in the period 1981–1998 and largely reduced by at least 39% in 1999–2019. Thus, particular caution is needed in studying the QBO based on CRA-40. Compared to the lower and middle stratosphere, all the three reanalyses have greater disagreement in the upper stratosphere in both the polar region and the tropics.
