A low - level jet is a narrow band of strong winds in the lower atmosphere 低空急流是在大氣低層出現(xiàn)的狹窄強風帶。

Scientists tried to seek explanations from the dv of low - level jet as a member of the meiyu precipitating system 過去曾從低空急流日變化等一些梅雨系統(tǒng)的內(nèi)部聯(lián)系尋求解釋。
The low - level jet stream has three vibration processes , which corresponded to the three lows " beginning and developing 低空急流有三次脈動過程,與三個低渦的產(chǎn)生和發(fā)展對應。
The low - level jet stream is the result of the spread of the momentum from the upper - level jet stream 低空急流是高空急流的動量向下輸送的結(jié)果。低空急流的生成先于水汽及降水的爆發(fā)。
The positive storm - relative helicity center is accompany with low - level jet in 850 - hpa isobaric surface fields 通過分析我們發(fā)現(xiàn)了正的相對螺旋度中心與850hpa低空急流的演變過程是一致的。
Severe convergence brought by low - level jet pulsation , and severe divergence brought by upper - level jet is directly trigger mechanism of this intense rainstorm 低層低空急流脈動產(chǎn)生的強輻合,高空急流誘發(fā)的高層強輻散是本次東北地區(qū)暴雨天氣的直接觸發(fā)機制。
The results show that the event is directly affected by the formation and evolution of southwest vortex and mcc cloud cluster which locate in the intersection region of the upper - level jet and the low - level jet 結(jié)果表明:高、低空急流耦合區(qū)中西南低渦及mcc特徵云團的形成和維持是造成此次特大暴雨的直接影響系統(tǒng)。
