摘要利用高时空分辨率的卫星降水资料，分析了2003 - 2010年四川盆地及邻近山区夏季雨季平均降水的空间变异和日传播特征。SCB位于青藏高原（TP）的东部，易于发生强降水，经常在夜间和清晨达到峰值。雨季SCB上空的大尺度环境特征是在TP的背风面有弱的中低层辐合，而在北部有对流层上层急流。在这种流动配置下，这项研究将降水模式和传播的独特日变化与该地区独特的地形联系起来。结果表明，在雨季，局地日降水量最大值主要向下坡和东南方向移动，从白天的TP到夜间的SCB。次极大值向东北下坡移动..
AbstractThe spatial variability and diurnal propagation of mean precipitation in the summer rainy seasons (from 2003 to 2010) over the Sichuan basin (SCB) and adjacent mountainous regions are examined using high spatiotemporal resolution satellite-derived precipitation estimates. The SCB is located just east of the Tibetan Plateau (TP) and is prone to heavy precipitation that often peaks over nighttime and early morning. The large-scale environment over the SCB during the rainy season is characterized by weak low- to midtropospheric convergence in the lee of the TP and by the upper-tropospheric jet stream to the north. Under this flow configuration, the study links the unique diurnal variations in the precipitation pattern and propagation to the unique topography in this region. It is found that during the rainy season, the local diurnal precipitation maximum moves primarily downslope and southeastward, from over the TP in the daytime to SCB at night. A secondary maximum moves northeastward downslope of t...
