Paper Abstract

Through analyzing the mesoscale disturbance field of a Meiyu rainstorm, it is found that there are close relations between the development and propagation of inertia-gravitational waves, rain belts and low vortex. The propagating patterns of inertia-gravitational waves are different in the upper and lower levels. In the early period of precipitation, convective instability triggers the inertia-gravitational waves. When there are inertia-gravitational waves propagating southward in the upper and lower levels, it is favorable to form multi-rain belts. In the mid of precipitation, the inertia-gravitational waves in the upper-layer rotate anticlockwise with the lower-layer vortex center, and precipitation strengthens and moves eastward in the meantime. The inertia-gravitational waves propagating northward in the upperlayer may result in the development of the lower-layer vortex and precipitation.
