Statistic Character and Dynamic Analysis of Upper Level Jet Streams on Sandstorm Days Study and application of numerical calculation method for gas flow distribution of electrostatic precipitation 沙尘暴天气的高空急流统计特征及动力学分析大型电除尘器气流分布数值计算的研究和应用
The conver gence stream field of the upper level jet stream and low level jet stream play an important part in the emergence and development of the MCC. 高、低空急流和低层辐合流场对MCC的生成和发展具有重要的作用。
The numerical results show that the upper level jet intensifies greatly the occluded frontal circulation and vertical velocity in frontal zone, and it is advantageous to propagate vertically internal gravity waves excited in frontal zone. 数值结果显示,在干大气中,高空西风急流的存在使锢囚锋非地转环流和锋区上升速度迅速变化、增强,并有利于重力内波的垂直传播;
Numerical Experiment of Effects of the Upper level Westerly Jet on a Torrential Rain over the Middle-lower reaches of the Yangtze River 高空西风急流对长江中下游暴雨影响的数值试验
In the sensitive experiment, the technique used to strengthen / weaken the upper level westerly jet ( SJet / WJet ) is reasonable as well as feasible. 模式敏感性试验中高空西风急流增强(SJet)/减弱(WJet)的方法是合理的、可行的;
