摘要: 通过华南暴雨实验获得的8次暴雨过程的资料分析,发现这些暴雨过程行星边界层下部都伴见1—2支中间尺度的偏南风强风带,它和常见的西南风低空急流有显著不同,为易于区别,称为超低空急流。分析看到,超低空急流和华南初夏的暴雨有着密切关系。Abstract: In this paper, the eight cases of heavy rain over South China are analysed It shows that the process of the heavy rain associated with the 1-2 ultra low-level jets-southerly jets of sub-synoptic scale at low-level in boundary layer.It is a significant factor of heavy rain in early summer over South China.
