Abstract:
This paper analyzed structure characteristics of convective clouds over the area between the Yangtze River and the Huaihe River based on Doppler radar data during 2013-2014. The used 227 convective cloud cases are classified into nine structure types. Then, we found that the isolated cell (IC), clusters of cells (CC), nonlinear systems (NL) are the dominant convective clouds over this area, accounting for 29.1%, 18.1%, and 23.3% of the total respectively. Different structural convective clouds occur under different weather backgrounds. Isolated cell is the main convection in the trough I pattern; nonlinear system is the major convection in the trough II pattern. At the same time, other structural convective clouds also occur frequently due to the common synoptic conditions. The convective clouds detected by the CFMCW radar show higher resolution of IC, CC and NL cloud structure images and the maximum falling speeds of precipitation particles, reaching 13.3 m·s-1, 8.2 m·s-1 and 11.5 m·s-1, respectively.
