Multiple-Input Describing Functions and Nonlinear System Design

Arthur Gelb, +1 more
TL;DR: The theory of automatic control has been advanced in important ways during recent years, particularly with respect to stability and optimal control, but these theories do not, however, lay to rest all questions of importance to the control engineer.

On the Characteristics of Gravity Waves Generated by Atmospheric Shear Layers

D. P. Lalas, +1 more
- 01 Jul 1976 - 
TL;DR: In this article, the stability analysis of a hyperbolic tangent velocity profile in an isothermal atmosphere in the presence of the ground is presented, and it is shown that such a system has a number of modes in addition to the one studied by Drazin and that unstable waves can he excited, for finite values of some minimum Richardson number of the flow, even in the limit of horizontal wavelengths going to infinity.

Microscale ordered motions and atmospheric structure associated with thin echo layers in stably stratified zones

James I. Metcalf, +2 more
- 01 Apr 1973 - 
TL;DR: In this article, the interpretation of ultra-high resolution radar observations of thin clear-air echo strata is made with the aid of fine-scale aircraft measurements, and two possible sources of the echoes are proposed: (1) scatter from fully developed turbulence within the interfacial zone in an inertial subrange falling entirely in sub-meter scales; and (2) the incoherent summation of specular reflections from properly oriented portions of the microscale K-H ripples.
