湿斜压波的理想化模拟研究解决了湿上升气流的形成，即所谓的暖传送带（WCBs），它们的特征，以及它们对下游气流演变的意义。斜压波模拟是在f平面上进行的，从一个纬向均匀急流的有限振幅上层位涡（PV）扰动增长。这种非模态的方法允许分散的上游和下游的发展，并研究在初级旋风分离器和下游旋风分离器的WCB。一个饱和度的调整方案被用来作为唯一的区别之间的干燥和潮湿的模拟，这是系统的比较使用气旋跟踪算法，涡动动能预算分析，并从PV的角度来看。使用轨迹和选择标准的最大上升，向前和向后倾斜的WCB在潮湿的模拟确定。在干燥模拟中未识别出WCB。前向倾斜WCB源于...
AbstractThis idealized modeling study of moist baroclinic waves addresses the formation of moist ascending airstreams, so-called warm conveyor belts (WCBs), their characteristics, and their significance for the downstream flow evolution. Baroclinic wave simulations are performed on the f plane, growing from a finite-amplitude upper-level potential vorticity (PV) perturbation on a zonally uniform jet stream. This nonmodal approach allows for dispersive upstream and downstream development and for studying WCBs in the primary cyclone and the downstream cyclone. A saturation adjustment scheme is used as the only difference between the dry and moist simulations, which are systematically compared using a cyclone-tracking algorithm, with an eddy kinetic energy budget analysis, and from a PV perspective. Using trajectories and a selection criterion of maximum ascent, forward- and rearward-sloping WCBs in the moist simulation are identified. No WCB is identified in the dry simulation. Forward-sloping WCBs originat...
