Static stability of atmosphere

WebStatic stability is seen to increase the minimum frequency f. These motions are never in a state of geostrophic balance, so they play an important role in the transient adjustments … WebStability criteria can also be expressed in terms of potential temperature. For unsaturated conditions, = T p 0 p (10) Taking the derivative with respect to zyields: 1 d dz = 1 T dT dz + g c p = 1 T [d] (11) A layer within the troposphere in which <0 or dT=dz >0 is called an inversionlayer where the air is stably stratified.

Neutral Stability N2 = 0 = d. The environmental lapse rate decreases with height at the same rate as the parcel’s temperature. The buoyancy force vanishes and the displaced parcel experiences no restoring force. The atmospheric layer is said to be hydrostatically neutral.

WebThe property responsible for the distinctly different character of the troposphere and stratosphere is vertical stability. Because it applies even under motionless conditions and … WebThe restoring atmospheric motion in a statically stable atmosphere is strictly vertical. When the atmosphere is statically unstable, then any vertical departure leads to buoyancy. This buoyancy leads to vertical accelerations away from the point of origin. In the context of this chapter, stability is used interchangeably with static stability.
