论文摘要
单层模型用于构建直线射流理论。除固定状态外，这种喷气机的演变还接受了横向搏动。该理论预测，温暖喷气脉动的时期比地球旋转引起的惯性振荡时期更长，而对于冷射流脉动，它的时间较短。因此，只有温暖的喷气机可以对风速光谱的概要范围产生明显的影响，从而在其中产生其他光谱峰。在这种方法中，每个射流都由自相似的紧凑型局部解决方案描述，该解可以被视为恒剪切带。
A single-layer model is used to construct the theory of straight-line jets. In addition to stationary states, the evolution of such jets admits transverse pulsations. The theory predicts that the period for warm jets pulsations is longer than the period of inertial oscillations caused by the Earth's rotation, while for cold jets pulsations, it is shorter. Thus, only warm jets can have a noticeable effect on the synoptic range of the wind-speed spectrum, generating into it additional spectral peaks. Within such an approach, every a single jet is described by a self-similar compactly localized solution that can be considered as a constant-shear band.
