通过一次暴雨过程，检验了中尺度重力波对暴雨的触发作用。检验结果和理论吻合：暴雨过程地面有中低压和中高压相伴出现，暴雨中心并不与地面中低压中心重合，而是位于中低压和中高压之间且偏于高压一侧。 Through a rainstorm process, the triggering effect of mesoscale gravity waves on heavy rainstorms was tested. The test results are in accordance with the theory. During the rainstorm process, the middle and low pressure and the middle and high pressure are accompanied by the ground surface. The rainstorm center does not coincide with the middle and low pressure center of the ground, but is located between the middle and low pressure and the middle and high pressure and the high pressure side.
