Figure 15

A schematic illustration of weather system configuration (a) and schematic diagram of the vertical circulation (b) in this abnormal heavy rainfall. In (a), LLJ—low-level jet; ULJ—upper-level jet; the solid contours—500 hPa geopotential height (units: gpdam); the broken contours—the contours of pseudoequivalent potential temperature (, units: °C). In (b), J_u—the ULJ axis.
