Conditional instability
WebA thermodynamic diagram showing the stability of the atmosphere based on the dry (Γ d = 9.8 K km -1) and moist (Γ m = 4.5 K km -1) adiabatic lapse rates (Created by Britt … WebApr 25, 2012 · See parcel method, conditional instability, absolute stability. ( Also called mechanical instability .) The state of a column of air in the atmosphere when its lapse rate of temperature is greater than the autoconvective lapse rate. In such a column the air density would increase with elevation. See also autoconvection.

Webconditional instability, convective instability, and forced lifting of air near the surface. For the purposes of this study, I chose to look into conditional and convective instability. Conditional instability can be defined in two ways. Using the lapse rate definition, conditional instability is when the environmental lapse rate of a parcel lies WebConditional stability occurs when the environmental lapse rate is between the moist and dry adiabatic rates. The atmosphere is normally in a conditionally unstable state. Many factors lead to instability. One is a …
WebAbsolute Instability-- Any layer in the atmosphere where the rate of actual temperature decrease with height is greater than 9.8 C/km (rapid cooling with height). On a sounding these are termed superadiabatic lapse rates. They most commonly occur at the surface during strong solar surface heating.

In the theory of dynamical systems, a state variable in a system is said to be unstable if it evolves without bounds. A system itself is said to be unstable if at least one of its state variables is unstable. In continuous time control theory, a system is unstable if any of the roots of its characteristic equation has real part greater than zero (or if zero is a repeated root). This is equivalent to any o… WebInstability in control systems [ edit] In the theory of dynamical systems, a state variable in a system is said to be unstable if it evolves without bounds. A system itself is said to be unstable if at least one of its state variables is unstable. In continuous time control theory, a system is unstable if any of the roots of its characteristic ...
