摘要
本文发现在200百帕高空急流区存在着强烈的非地转现象,它可激发出大尺度的稳定的重力惯性波,并向周围传播。在高空急流右后方波能量最易发展加强。重力惯性波的形成、维持和移动也决定了暴雨的形成、维持和移动。
In this study a strong ageostrophic wind is observed in the 200 hPa upper tro-pospheric jet, which causes a large-scale gravity-inertia internal wave to propagateabout. In the right rear of the upper-level jet the wave energy is more easily developedand strengthened. The formation, maintenance and propogation of the wave determinethose of the heavy rain.
