The interaction between the southern low level jet and weaker cold air of ground layer from northern North China led to initiation and development of the cloud clusters. 该云团的形成和发展,是偏南风低空急流(LLJ)与华北北部南下的近地面层弱冷空气相互作用的结果。
Furthermore, the model can represent the daily variation of the low level jet, which is crucial in the water vapor transport to the Yangtze-Huaihe valley. 而且,模式能够较好地再现出对水汽输送至关重要的低空急流(LLJ)的逐日变化。
When the baroclinicity of southwest vortex had not been built and where cold front existed, the rain belt may lie in anywhere of the left of southwest low level jet. 在西南涡斜压性未建立之前以及冷锋附近,暴雨区可位于低层西南风急流左侧的任何位置。
But the propagation directions of both K and v are rather disorderly between the Bay of Bengal and the Somalia low level jet channel. 而在孟加拉湾动能中心与索马里急流区之间,动能传播方向比较复杂。
Therefore, the existence of moist low level jet in the south or south-west of the rainfall region is favorable to the development of the lid. 因此雨区南侧低空偏南湿急流的存在对雨区暖盖的增强极为有利。
