| 英文摘要 | Investigated with a regional climate model based on laboratoire de meteorologie dynamique zoom (lmdz4-rcm). a control experiment is performed with two runs driven by the mean era-40 data during 1958-1977 and 1981-2000, respectively. the model reproduces the major decadal-scale circulation changes in late spring over east asia, including a cooling in the upper troposphere and an anomalous meridional cell. accordingly, the precipitation decrease is also captured in the southeast of the upper-level cooling region. to quantify the role of the upper-level cooling in the drought mechanism, a sensitivity experiment is further conducted with the cooling imposed in the upper troposphere. it is demonstrated that the upper-level cooling can generate the anomalous meridional cell and consequently the drought to the southeast of the cooling center. therefore, upper tropospheric cooling should have played a dominant role in the observed late spring drought over southeast china in recent decades. |
